Available in PDF, EPUB and Kindle. Book excerpt: This report describes an innovative design for prestressed precast reinforced concrete joists. The joist is a hybrid design that uses large web openings for passage of environmental pipes and ducts, replicating an advantage of steel truss construction. The design also exploits the stiffness and strength of precast concrete double-tee beams. Alternative designs were investigated by varying parameters such as concrete strength, prestressing strand layout, and reinforcement. Test results from eight hybrid joists are presented to substantiate finite element analysis results, and a simple method for designing the beams is presented. It is concluded that hybrid joist demonstrates remarkable performance and the capability to behave like a conventional double-tee beam. The behavior of the hybrid joist meets the requirements of ACI 318-95. Experimental failure loads were very high compared with design service and ultimate loads. The analytical and experimental results indicate that the hybrid joist has a predictable ductile response, and the experimental results verify that the analytical model provides a reliable and simple method for determining the load-deflection response. Vibration analysis showed that the hybrid joist has acceptable response to established criteria and compares well with the response of both concrete and steel bar joists.

This book was released on 1997 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conventional precast reinforced concrete double-tee joists may be made more structurally efficient by incorporating large openings in the web to accommodate environmental pipes and ducts. Double-tee joists with web openings may also reduce the total required building height, which would significantly lower costs for labor and materials during new construction. This report presents a method for designing prestressed precast reinforced concrete double-tee joists with web openings. Alternative designs were investigated by varying parameters such as prestressing strand layout, opening pier width, and pier reinforcement. Test results from six prestressed concrete joists are presented to substantiate finite element analysis results. The effect of web openings on beam behavior is discussed, and a simple method for designing the beams is presented. It is concluded that double-tee joists can be designed and manufactured with many web openings without jeopardizing beam strength. However, due to the effect of concentrated loading on shear failure modes in the tests, double-tee designs with web openings are recommended only floor and roof applications where only uniform loading will occur. Material costs associated with this design are slightly higher than for conventional double-tee members, but the design promotes an overall reduction in new construction costs.
Book Synopsis Analysis and Validation of Design Guidelines Proposed for Precast Concrete Hybrid Frame Systems by : Onur Celik
Download or read book Analysis and Validation of Design Guidelines Proposed for Precast Concrete Hybrid Frame Systems written by Onur Celik and published by . This book was released on 2004 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Utilizing component and system level performance verification tests, the precast hybrid frame concept has been developed for seismic applications over the past decade. During the course of this development, guidelines for designing hybrid frame connections have been proposed. The main objective of this study is to examine validation of the three different guidelines proposed recently for the design of hybrid frame systems using existing data from two component and one system level tests. The validation procedure involves establishing analysis methods based on the proposed design steps and assumptions, and comparing the analysis results with the experimental data. Since experimental data were not available for all key design parameters, the analysis results are also compared with those obtained from the analysis based on the monolithic beam analogy concept. Using the comparison of results obtained from different means, validation for the design guidelines and appropriate recommendations to improve the design of precast concrete hybrid frame connections are provided.

Download or read book Hybrid Composite Precast Systems written by Won-Kee Hong and published by Woodhead Publishing. This book was released on 2019-11-30 with total page 493 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hybrid Composite Precast Systems: Numerical Investigation to Construction focuses on the design and construction of novel composite precast frame systems that permit almost effortless erection and structural efficiency. The precast frame systems discussed in the book are similar to that of steel frames, but offer similar savings to concrete frames. The design of connections and detailed analysis of their structural behavior is discussed in detail. Fundamentals with regards to the post yield behavior of concrete and metal are also presented to illustrate how these two different materials are integrated together to remove individual material drawbacks. Readers are given a broad introduction to existing technologies that are then combined with a description of the construction methods the author proposes. This book will help the end users become familiar with the existing types of structural forms, not just the "Lego" type frame system that the author proposes. Discusses how traditional construction methods can be replaced by innovative hybrid composite precast frame systems that provide rapid and effortless erection capabilities and structural efficiency Contains several design examples using non-linear finite element analysis completed with Abaqus based-software Contains new milestone inventions in construction that offer structural engineering solutions using a novel, modularized hybrid frame system Provides information on structural testing that verifies the accuracy of the structural design
Book Synopsis High-performance Hybrid-fibre Concrete by : Ivan Marković
Download or read book High-performance Hybrid-fibre Concrete written by Ivan Marković and published by IOS Press. This book was released on 2006 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In the research project presented in this PhD-thesis, an innovative type of fibre concrete is developed, with improved both the tensile strength and the ductility: the Hybrid-Fibre Concrete (HFC). The expression "Hybrid" refers to the "hybridisation" of fibres: short and long steel fibres were combined together in one concrete mixture. This is opposite to conventional steel fibre concretes, which contain only one type of fibre. The basic goal of combining short and long fibres is from one side to improve the tensile strength by the action of short fibres, and from the other side to improve the ductility by the action of long fibres." "In this research project, all important aspects needed for the development and application of Hybrid-Fibre Concrete have been considered. In total 15 mixtures, with different types and amounts of steel fibres were developed and tested in the fresh state (workability) as well as in the hardened state (uniaxial tensile tests, flexural tests, pullout tests of single fibres and compressive tests). A new analytical model for bridging of cracks by fibres was developed and successfully implemented for tensile softening response of HFC. At the end, the utilisation of HFC in the engineering practice was discussed, including a case-study on light prestressed long-span beams made of HFC."--BOOK JACKET.
