Book Description
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 Description
Terrorist attacks and other destructive incidents caused by explosives have, in recent years, prompted considerable research and development into the protection of structures against blast loads. For this objective to be achieved, experiments have been performed and theoretical studies carried out to improve our assessments of the intensity as well as the space-time distribution of the resulting blast pressure on the one hand and the consequences of an explosion to the exposed environment on the other.This book aims to enhance awareness on and understanding of these topical issues through a collection of relevant, Transactions of the Wessex Institute of Technology articles written by experts in the field. The book starts with an overview of key physics-based algorithms for blast and fragment environment characterisation, structural response analyses and structural assessments with reference to a terrorist attack in an urban environment and the management of its inherent uncertainties.A subsequent group of articles is concerned with the accurate definition of blast pressure, which is an essential prerequisite to the reliable assessment of the consequences of an explosion. Other papers are concerned with alternative methods for the determination of blast pressure, based on experimental measurements or neural networks. A final group of articles reports investigations on predicting the response of specific structural entities and their contents.The book concludes with studies on the effectiveness of steel-reinforced polymer in improving the performance of reinforced concrete columns and the failure mechanisms of seamless steel pipes used in nuclear industry.

Book Description
Reinforced concrete is one of the prime building materials widely used to construct protective structures. One of the purposes of this project is to study the non-linear response of reinforced concrete structures when subjected to impact and blast loading. The study is conducted at two levels: material level and structural level. At the material level, the strength enhancement of three material models of LS-DYNA subjected to high strain rates is studied. The effects of strain rate and lateral inertial confinement on the strength enhancement are investigated. Recommendations are made to improve the accuracy of the results of future numerical simulations for reinforced concrete structures subjected to loads having high strain rates. At the structural level, Pressure-Impulse diagrams for reinforced concrete columns that have four configurations of transverse reinforcement are developed. Finite element modeling in LS-DYNA is used to analyze the structures and calculate the damage level for each blast event. The developed Pressure-Impulse diagrams are used to study the effect of confinement on the reduction of damage level at impulsive, dynamic, and quasi-static loading conditions.

Book Description
This book is concerned with the dynamic behavior of reinforced/prestressed concrete structures, such as: buildings and bridges. It discusses how to predict or check the real inelastic behavior of concrete structures subjected to dynamic loads, including equipment loads, earthquake motions, seismic interactions and missile impacts. A number of techniques have recently been developed to assist in evaluating such occurrences. This book is intended to apply structural dynamics to concrete structures and is appropriate as a textbook for an introductory course in dynamic behavior of concrete structures at the upper-undergraduate or graduate level as well as for practicing engineers.

Book Description
The analysis of reinforced and prestressed concrete elements under blast and impact loading is drawing the interest of many researchers due to increasing number of natural or human-made hazards that require attention. The analysis methods used are mainly based on either simplified single degree-of-freedom methods or highly sophisticated and complex hydrocodes. Although single degree-of-freedom methods are commonly used by designers for practical reasons, they are incapable of providing detailed results such as deformed shapes and crack maps. Additionally, since they require simplification of the structure to a single degree-of-freedom system, they are difficult to apply to complex geometries. On the other hand, hydrocodes overcome the limitations associated with the simplification of the structure. However, they require highly detailed models which require significantly increased modelling and computational time. Moreover, the accuracy of blast and impact analyses with hydrocodes heavily relies on the material input parameters which are not commonly known. Thus, there remains a need for accurate, simplified and reliable tools for analysis of reinforced and prestressed concrete subjected to blast and impact loading. The VecTor family of nonlinear finite element programs, using a macro-element smeared rotating crack approach, has been shown to be accurate in predicting the response of shear-critical structures under quasi-static conditions. In this study, two members of this suite, VecTor3 and VecTor6, were adapted for the blast and impact analyses of reinforced and prestressed concrete structures in 3D and axisymmetric conditions, respectively. The results obtained from the simulations were close to those experimentally observed. Additionally, a semi-analytical formula for the prediction of perforation velocity from missile impact was developed. The formula, which is based on the Modified Compression Field Theory, considers the influence of longitudinal and shear reinforcement in the target differently from other commonly used empirical formulae. The formula was validated with numerous missile impact data available in the literature, and good accuracy was found.
