Available in PDF, EPUB and Kindle. Book excerpt: Six explosive tests were conducted against reinforced concrete walls to determine the effect of steel reinforcement design on structural response and damage. Reinforcement percentages varying from 0.25 to 2.0 and two reinforcement designs (one with shear stirrups and one with shear dowels) were tested. Test specimens consisted of box structures with 32.5-cm-thick walls. Cased-explosive charges were detonated on the ground near one of the walls of the box. Test structures were instrumented to record blast-pressure loading, steel strains, wall deflection, in-structure acceleration, and concrete-spall velocities. Damage to the walls (similar for all tests, differing only in severity) consisted of a region near the bottom center where the concrete on the wall interior spalled and cracked coupled with a flexural-type response. The loading of the walls was more severe than predicted and the majority of the structural damage was due to spalling. (Author).

Book Synopsis UHPCC Under Impact and Blast by : Qin Fang
Download or read book UHPCC Under Impact and Blast written by Qin Fang and published by Springer Nature. This book was released on 2021-02-22 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is about the Ultra-high Performance Cementitious Composites (UHPCC), which is a relativity new type of cementitious materials. UHPCC has very low water-to-binder ratio, high amount of high-range water reducer, fine aggregates and high-strength steel or organic fibers. With the prominent mechanical properties, e.g., high compressive and tensile strength, high ductility, and high fracture energy, UHPCC has been becoming the most prospective construction cement-based material for both civil and military structures to resist high-speed projectile penetration, low-velocity impact and blast loadings. In this book, the related work conducted by authors on the static and dynamic mechanical properties, as well as the impact and blast resistance of UHPCC are presented. This book is written for the researchers, engineers and graduate students in the fields of protective structures and terminal ballistics.
Book Synopsis Assessment of Prestressed Reinforced Concrete Box Girder Bridges Under Blast Loads by : Ahmed Abdel Rahman A. Ibrahim

This book was released on 2010 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Significant research has been performed on the response and retrofit of buildings under blast loads. Limited research exists on the response prediction and protection of bridges under near-field blast loads. This research focuses on the evaluation of box girder bridges under blast loads. The objective of this research is to develop analytical and numerical models to predict the damage level in a concrete deck under blast loading and the corresponding dynamic response of the damaged bridge system. The numerical analysis starts from the verification of blast pressure in the free air using explicit LS-DYNA with the Arbitrary Lagrangian Eulerian (ALE) system of equations, followed by predicting the damage level on concrete panels under different charge weights and standoff distances and finally evaluating the dynamic response of bridge superstructure using the predominant damage levels. In addition, an analytical formulation will be presented to predict damage level of concrete structures under blast loading. Key parameters were studied during the analysis, such as the weight of the charge, the standoff distance, and concrete deck properties. Preliminary simulation results compared well with existing experimental blast test data on concrete panels for predicting the damage level. Simple analytical models for predicting the spalling/breaching of concrete walls under blast are development and will be refined using the numerical parametric study. An Artificial Network model (ANN) for predicting the concrete damage under near field blasts is also developed based numerical simulations of 125 slab blast configurations. The results compared reasonable well with existing empirical methods.

Book Synopsis Concrete Structures Subjected to Impact and Blast Loadings and Their Combinations by : Chunwei Zhang
Download or read book Concrete Structures Subjected to Impact and Blast Loadings and Their Combinations written by Chunwei Zhang and published by CRC Press. 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.
Book Synopsis Radiation Shielding and Response Studies of AEC Test Structures by : R. A. Cameron
Download or read book Radiation Shielding and Response Studies of AEC Test Structures written by R. A. Cameron and published by . This book was released on 1962 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: The energy-dependent film badges, which also were strongly direction dependent, indicated that the radiation near the bottom of the structures was approximately isotropically distributed. However, calculated doses at individual badge locations based on the isotropic distribution did not agree well with observed doses. In all cases the peak accelerations recorded inside the shelters were higher than the corresponding free-field peaks. Consequently it is recommended that until further information is available, the predicted free-field peak motions (acceleration, velocity, and displacement) be multiplied by 1.5 to predict the corresponding peaks inside structures similar to those observed in this test.
