This book was released on 2014 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: Blasts and impacts are two of the severest loads a structure can experience. Blast experimenters, however, have observed that the load imparted to a circular member was lower than the predicted design load. Additionally, numerous investigations have established the superiority of concrete filled FRP tubes (CFFTs) over conventional reinforced concrete members. These observations indicated CFFTs' potential to resist dynamic blast and impact loads. The experimental and numerical investigations presented in this thesis aimed to demonstrate the suitability of CFFTs to resist blast and impact loads, to determine the parameters that influence their behaviour under such loads, and to develop a design procedure for resisting these loads. The initial numerical investigation determined the reflected blast loading parameters experienced by a circular cross section. The experimental phase consisted of testing twelve full scale specimens, two monotonically, four under impact loading, and six under close-in blast loading. The monotonically tested specimens acted as controls for the entire program. The results of the impact testing investigation were used to develop and validate a non-linear single degree of freedom (SDOF) model. This impact phase also led to the development of relatively simple procedures for designing CFFTs under impact loading using either SDOF modeling or the conservation of energy. Analysis of the blast testing results led to the development of numerical procedures for obtaining an equivalent close-in blast loading for SDOF analysis of CFFTs and Pressure-Impulse diagrams. The use of SDOF modeling and conservation of energy in blast design were also discussed. Finally, a non-linear explicit dynamic model of CFFTs was developed using the commercial software ANSYS Autodyn. This model was verified using the experimental impact and blast test results and used to conduct a parametric study. The results of these investigations indicated that CFFTs were particularly suitable for blast and impact resistant applications, as their geometry diffracted blast waves and the addition of the tube increased their energy absorbing capacity significantly giving them additional strength and ductility. The tube also confined and protected the concrete core and simplified construction.

This book was released on 2022-05-08 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although much research focuses on investigating the responses of reinforced concrete (RC) structures under sole impact or blast loads, the responses of RC structures under a combination of impact and blast loads currently represent a gap in our knowledge. The combined actions of impact and blast loadings may be applied to RC structures during accidental or intentional collision of vessels, vehicles, etc., carrying explosive materials. A comprehensive study on the vulnerability of various structural members is carried out using finite element (FE) simulations under combination of impact and blast loads with the variations of various loading- and structural-related parameters and key parameters. This book introduces various structural analysis approaches for concrete structures when subjected to extreme loads such as impact and blast loadings. The theory of the combinations of impact and blast loads is proposed that can provide primary insights to the specific readers to develop new ideas in impact and blast engineering, including combined actions of extreme loads arising from real-world intentional or accidental events. This book will be of value to students (undergraduate or postgraduate), engineers, and researchers in structural and civil engineering, and specifically, those who are studying and investigating the performances of concrete structures under extreme loads.

This book was released on 2011 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: [Truncated abstract] Reinforced concrete (RC) structures might subject to severe impulsive loadings due to shock wave, blast wave or direct impact in their service life. The Fiber Reinforced Polymer (FRP) strengthening concepts have been used in many studies to strengthen these RC structures in resisting progressive collapse, structural damage and preventing injuries against dynamic explosive impacts. Its effectiveness in strengthening RC structures to resist blast and impact loads have been proven in both numerical and experimental studies. However, there are limited systematic studies that directly correlate the increase in structural capacities in resisting the blast loads with the strengthening measures, such as the strengthening materials, layers of FRP applied and types of epoxy used. The pressure-impulse (P-I) curves are often used to quantify structural performance under various blast loading scenarios. By developing P-I curve for FRP strengthened structures, the quantitative correlation between minimum peak pressure and impulse required to reaching a particular level of damage of FRP strengthened and unstrengthened columns can be plotted. In this research, the assessment on the failure modes and dynamic response of structures with FRP strengthening under different condition of impact and blast loading are determined. To achieve this two experimental programs (Chapter 2 and 3) and a series of numerical analyses (Chapter 4-7) are carried out. The experimental programs determine the effects of different types of Carbon Fiber Reinforced Polymer (CFRP) strengthening approaches on the dynamic response of RC structural elements under impact loads. The first experimental program involves of static and impact loading on the CFRP strengthened RC beams. Three types of CFRP strengthening approaches are selected as follows: a) one of CFRP longitudinal strip is applied on the tension zone of the RC beam; b) RC beam is wrapped by CFRP fabric; and c) RC beam is strengthened with combination of both CFRP longitudinal strip and wrap. In the second experimental program, the efficiency and performance of CFRP strengthening of RC slabs under repeated impact loads is examined. The selected CFRP strengthening approaches are as follows: a) two layers of CFRP fabrics applied with epoxy to the tension side with the second layer being placed in a perpendicular direction to the first layer; b) CFRP strengthened slab with anchors at the slab boundaries; and c) CFRP strengthened slab with anchors at the slab boundaries and more anchors around the middle span. Each slab is initially subjected to repeated impact loads until failure is reached...

Available in PDF, EPUB and Kindle. Book excerpt: This book develops several novel foam-filled structures and steel-concrete-steel (SCS) sandwich structures, which provides more alternatives for ensuring the safety of buildings and infrastructures under extreme loading, like impact and blast. In the first part of this book, the aluminium foam- and polyurethane foam-filled structures have been developed for dissipating impact and blast energy. Experimental and numerical studies have been conducted to obtain their behaviours under impact loading. In addition, analytical models have also been proposed to assess their energy absorption performances and facilitate the impact and blast design when using the proposed foam-filled structures. In the second part of this book, SCS sandwich structures with novel shear connectors have been developed and their behaviours under impact and blast loading have been experimentally, numerically and analytical studied. Analytical models for predicting the impact and blast responses of SCS sandwich structures have also been developed. In the third part of this book, a new steel-polyurethane foam-steel-concrete-steel (SPUFSCS) panel (i.e. the combination of foam material and SCS panel) has been developed to achieve a higher impact resistant capacity. Owing to the increasing impact and blast threats on buildings and infrastructures, the studies presented in this book are of significant importance for providing several new solutions for impact and blast enhancement.

Available in PDF, EPUB and Kindle. Book excerpt: This report is divided into three main subjects, e. g., beam response to impulsive loads of fuel-air explosions (FAE), effect of fuel-air explosions in confined unpressurized containers, and the effect of intense impulsive loads from surface blasts on material removal and degradation of a concrete semi-half space. Investigation into the response of small ductile beam elements subjected to blast loadings indicates a need for analysis of beams including gross deformation, axial constraints, and complete failure. The response of small beams to fuel-air explosions fall in a transition between a static mechanism and a traveling plastic hinge mechanism. Equations of motion, based on a strength of material approach, are derived for both mechanisms. The same general shock transmission and reflection of detonation waves are found to be operative in both confined and unconfined fuel-air explosions. The ratio of the reflected pressure to the static pressure of a detonation wave is dependent only on the ratio of specific heats and reaches a maximum of 2.6 for a specific heat ratio of infinity. Computational models are available and have been used with some success for prediction of cratering, material removal and material degradation for certain rock media and could be used for concrete; however, development of constitutive models for concrete is still in the fundamental stage. More fundamental research, especially experimental and theoretical work on material characterization, is needed before a reasonable damage estimation of concrete subjected to intense impulsive loads can be obtained.
