Book excerpt: Static Analysis methods originally developed for soils are currently used for estimating pile resistances in Intermediate Geomaterials (IGMs), and structural capacity has been considered as the limiting pile capacity on hard rocks. The application of current Load and Resistance Factor Design (LRFD) for piles in IGMs has resulted in relatively high uncertainties in pile resistance estimation during design and the length to which the piles are driven into IGMs during construction. Moreover, the absence of standard criteria to differentiate the geomaterials creates challenges in the design and construction of driven piles in IGMs. The application of a dynamic analysis method using Wave Equation Analysis Program is constrained by geomaterial input for IGMs and rocks. These current challenges have led to conservative pile resistance estimations. Thus, the overall objectives of this study were to determine efficient static analysis methods, dynamic procedures for construction control, pile setup/relaxation, and resistance factors for the estimation of the axial pile resistances in IGMs, ensuring a prescribed level of reliability to meet LRFD philosophy. To accomplish these objectives, classification criteria of geomaterials were first created to establish a standard quantitative delineation between the soils, IGMs, and hard rocks for the design of driven piles. In addition, a catalog of IGM properties was prepared to facilitate the preliminary design of piles in IGMs. Secondly, a new set of design equations were developed and validated for IGMs by utilizing the developed geomaterial classification criteria. Thirdly, wave equation analysis procedures for IGMs were recommended for pile construction control. Fourthly, changes in pile resistances in IGMs with respect to time at an End of Driving and Beginning of Restrike were assessed. Finally, probability based resistance factors were calibrated and recommended based on the efficiency factors for the existing and calibrated static analysis methods. Calibrated static analysis methods were concluded to have higher efficiency factors of 0.61, 0.30, and 0.41 against efficiency factors of 0.28, 0.09, and 0.14 corresponding to existing static analysis methods for shaft resistance estimation in IGMs. Similarly, calibrated static analysis methods were concluded to have higher efficiency factors of 0.24 and 0.48 against efficiency factors of 0.13 and 0.29 corresponding to existing static analysis methods for end bearing estimation in IGMs.

This book was released on 2021 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: Accurate and reliable methods to predict resistances of driven piles in intermediate geomaterials (IGMs) are essential for improving the economics of pile design and construction.However, static analysis methods for driven piles in IGMs are rarely available. Past experiences have suggested that estimating pile resistances in IGMs using the conventional static analysis methods for soils can lead to several problems regarding pile design and construction. Thus, this study aims to develop static analysis methods and Load and Resistance Factor Design (LRFD)resistance factors to facilitate the design of driven piles in claystone, sandstone, and mudstone. Moreover, Wave Equation Analysis Program (WEAP) has been widely used to determine drivability, predict static pile resistance, and assure the integrity of piles in soils. Assigning staticand dynamic properties of IGMs remains a challenge in WEAP, partly attributed to lack of reliablemethods for unit resistance predictions for driven piles in IGMs. The challenge is further exacerbated as the recommended Smith parameters were originally developed for piles in soils.Using 129 steel H- and pipe piles driven in IGMs, improved WEAP methods and newly calibrated LRFD resistance factors are recommended. These recommendations are based on proposed static analysis methods and back-calculated Smith parameters for IGMs. An additional 46 test pile data was used to validate the recommendations. Finally, the economic impact of these WEAPrecommendations on the design and construction control of driven piles in IGMs was studied,which confirmed the economic benefits of the proposed improved WEAP methods.

Book excerpt: Driven piles are the most common foundation solution used in bridge construction (Paikowsky et al., 2004). Their safe use requires to reliable verification of their capacity and integrity. Dynamic analyses of driven piles are methods attempting to obtain the static capacity of a pile, utilizing its behavior during driving. Dynamic equations (aka pile driving formulas) are the earliest and simplest forms of dynamic analyses. The development and the examination of such equation tailored for MnDOT demands is presented. In phase I of the study reported by Paikowsky et al. (2009, databases were utilized to investigate previous MnDOT (and other) dynamic formulas and use object oriented programming for linear regression to develop a new formula that was then calibrated for LRFD methodology and evaluated for its performance. This report presents the findings of phase II of the study in which a comprehensive investigation of the Phase I findings were conducted. The studies lead to the development of dynamic formulae suitable for MnDOT foundation practices, its calibrated resistance factors and its application to concrete and timber piles. Phase II of the study also expanded on related issues associated with Wave Equation analyses and static load tests, assisting the MnDOT in establishing requirements and specifications.

Available in PDF, EPUB and Kindle. Book excerpt: With the goal of producing engineered foundation designs with consistent levels of reliability as well as fulfilling the Federal Highway Administration (FHWA) mandate that all new bridges initiated after October 1, 2007 be designed according to the Load and Resistance Factor Design (LRFD) approach, the Iowa Highway Research Board (IHRB) sponsored three research projects on driven piles (TR-573, -583 and -584). The research outcomes are presented in three reports entitled Development of LRFD Design Procedures for Bridge Piles in Iowa, Volumes I, II, and III, and other research information is available on the project web site at http://srg.cce.iastate.edu/lrfd/. Upon incorporating the regional LRFD recommendations from the completed research into the Iowa DOT Bridge Design Manual (2010) as it is being rewritten under the new title of LRFD Bridge Design Manual (December 2011), and adopting the American Association of State Highway and Transportation Officials (AASHTO) LRFD Bridge Design Specifications (2010), this Volume IV for driven piles in Iowa was developed. Following the layout of a design guide, the application of the LRFD approach is demonstrated using various pile design examples in three different tracks, which depend on the construction control method used for establishing the pile driving criteria. Piles are designed using the Iowa Blue Book method. The pile driving criteria are established using the Wave Equation Analysis Program (WEAP) and the Pile Driving Analyzer (PDA) with a subsequent pile signal matching analysis using the CAse Pile Wave Analysis Program (CAPWAP) in Track 3. The track examples cover various pile types, three different soil profiles (cohesive, non-cohesive, and mixed) and special design considerations (piles on rock, scouring, downdrag, and uplift).

Available in PDF, EPUB and Kindle. Book excerpt: "Driven piles are widely used as foundations for buildings, bridges, and other structures. Since 1994, AASHTO (American Association of State Highway and Transportation Officials) has been in process to change from ASD (Allowable Stress Design) method to LRFD (Load and Resistance Factor Design) method for foundation design. The adoption of LRFD approach makes possible the application of reliability analysis to quantify uncertainties associated with various load and resistance components, respectively. Although there exist some recommendations for incorporation of set-up into ASD and quality control methods for driven piles, most of these recommendations were developed purely based on the engineering experience with no attendant database and reliability analysis. A successful application of probability approach will definitely result in significant improvements on the design and quality control of driven piles. Therefore, there is a need to develop the quality control criterion and to improve the LRFD of driven piles in the framework of reliability-based analysis. In this study, the new reliability-based quality control criteria on driven piles are developed based on acceptance-sampling analysis for various pile test methods with lognormal statistical characteristics. An optimum approach is recommended for the selection of the number of load tests and the required measured capacities for quality control of various load test methods of driven piles. The databases containing a large number of pile testing data are compiled for piles driven into clay and into sand, respectively. Based on the compiled databases, a new methodology is developed to incorporate set-up into the LRFD of drive piles using FORM (First Order Reliability Method) where the separate resistance factors for measured reference capacity and predicted set-up capacity are derived to account for different degrees of uncertainties associated with these two capacity components. Based on Bayesian theory, a new methodology is developed to optimize the LRFD of driven piles by combining the results from static calculation and dynamic pile testing. Specifically, the results from dynamic pile tests are incorporated to reduce the uncertainties associated with static analysis methods by updating the resistance factors in LRFD. Finally, a new one-dimensional wave equation based algorithm to interpret High Strain Testing data for estimation of resistances of driven piles is proposed."--abstract.

This book was released on 2000 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: The parameters for load and resistance factor design (LRFD) of driven piles using dynamic methods are presented based on a database of 218 pile cases in Florida. Eight dynamic methods were studied: ENR, modified ENR, FDOT, and Gates driving formulas, Case Analysis with Wave Analysis Program (CAPWAP), Case Method for Pile Driving Analyzer (PDA), Paikowsky's energy method, and Sakai's energy method. It was demonstrated that the modern methods based on wave mechanics, such as CAPWAP, PDA, and Paikowsky's energy methods, are roughly twice as cost effective to reach the target reliability indices of 2.0 to 2.5 (failure probability = 0.62 to 2.5%) as the ENR and modified ENR driving formulas. The Gates formula, when used separately on piles with Davisson capacities smaller or larger than 1779 kN, has an accuracy comparable to the modern methods. The utilizable measured Davisson capacity, defined as ?/? (ratio of resistance/mean capacity) obtained from testing at beginning of redrive (BOR), is only slightly larger than the end of drive (EOD) values. Furthermore, past practice with driving formulas reveals the existence of a large redundancy in pile groups against failure. The latter suggests the use of a lower relatively reliability target index, ?T = 2.0 (pf = 2.5%) for single pile design. Also, the utilizable measured Davisson capacity, ?/?, for all the dynamic methods studied, is quite similar to published values (Lai et al. 1995; Sidi 1985) for static estimates from in situ tests.

This book was released on 1998 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: Eight dynamic methods to estimate the static capacity of driven piles were evaluated based on a Florida database and Load Resistance Factor Design (LRFD). The dynamic methods investigated were four stress wave approaches (CAPWAP, PDA, Paikowsky Energy, and Sakai Energy) and four driving formulas (ENR, modified ENR, FDOT, and Gates). In the case of the older driving formulas, the database was broken into both small (i.e. Davisson capacity less than 1779 kN) and large (Davisson capacity larger than 1779 kN) capacity piles. It was demonstrated that the modern methods based on wave mechanics, such as CAPWAP, PDA, and Paikowsky's energy method, are more accurate than the old driving formulas. The utilizable measured Davisson capacity, defined as [phi]/[lambda][subscript]R (ratio of resistance / mean capacity), shows that the new dynamic methods are more cost effective to meet a reliability index in comparison with the old methods based on momentum conservation. In addition, the Gates formula, when used separately for Davisson capacity larger than 1779 kN or less than 1779 kN, may have comparable accuracy with the modern methods. A suggested empirical method is presented to calculate the total, skin, and tip static resistance of driven piles. This method has proved to be equally or more accurate than the most widely used method (i.e. PDA, and CAPWAP). Additional features of the suggested method include determining the total, skin, and tip static capacities as the piles are being driven, saving construction time, therefore, saving construction costs.

Available in PDF, EPUB and Kindle. Book excerpt: The current use of the Arkansas Standard Specifications for Highway Construction Manuals (2003, 2014) for driven pile foundations faces various limitations which result in designs of questionable reliability. These specifications are based on the Allowable Stress Design method (ASD), cover a wide range of uncertainties, do not take into account pile and soil types, and were developed for general use. To overcome these challenges it is deemed necessary to develop a new design and acceptance protocol for driven piles. This new protocol incorporates locally calibrated RLFD resistance factors for accounting for local design and construction experiences and practices, as well as specific soil conditions and pile types. In that perspective, this dissertation focuses on the design and acceptance of driven pile foundations (predominately for bridge projects) using an LRFD protocol. A great deal of insight is gained into the factors that contribute to the performance of deep foundations by conducting an extensive literature review. The research assembled a relatively large database of pile load tests where both static and dynamic load testing was performed and sufficient soils information existed to perform static design calculations. A MATLAB® based program was developed to use the information contained in the database to compute resistance factors for driven piles using the First Order Second Moment Method (FOSM), Improved FOSM, the First Order Reliability Method (FORM), and Monte Carlo Simulations (MCS). The research also addressed a technique to update resistance factors using Bayesian techniques when new load tests are added to the database. More importantly the dissertation formulated a design and acceptance protocol that seeks to unify the level of reliability for deep foundations through both the design and construction phases. As a verification mechanism to the developed design and acceptance protocol, a full-scale pile load testing program was recommended. The testing program would be composed of ten driven piles that had been dynamically and statically load tested. It was found that, for the same required reliability level, acceptance criteria could be lowered if more piles are tested on a jobsite. Subsequently, a non-contact instrument--such as Pile Driving Monitoring device-is recommended to verify in situ pile capacity of each and every pile on construction site. The results from in situ pile capacity verification could be employed to update the calibrated resistance factors and to refine future designs.
