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.

Download or read book Structures Under Shock and Impact XIII written by G. Schleyer and published by WIT Press. This book was released on 2014-06-03 with total page 513 pages. Available in PDF, EPUB and Kindle. Book excerpt: SUSI XIII contains the proceedings of the 13th International Conference in the successful series of Structures Under Shock and Impact. Since the first meeting in Cambridge, Massachusetts (1989) the conference has brought together the research works of scientists and engineers from a wide range of academic disciplines and industrial backgrounds that have an interest in the structural impact response of structures and materials. The shock and impact behaviour of structures is a challenging area, not only because of the obvious time-dependent aspects, but also due to the difficulties in specifying the external dynamic loadings, boundary conditions and connection characteristics for structural design and hazard assessment, and in obtaining the dynamic properties of materials. Thus, it is important to recognise and utilise fully the contributions and understand the emerging theoretical, numerical and experimental studies on structures, as well as investigations into the material properties under dynamic loading conditions. Any increased knowledge will enhance our understanding of these problems and thorough forensic studies on the structural damage after accidents will lead to improved design requirements. The range of topics in this very active field is ever expanding. The following list of topics gives an idea of the wide number of applications covered: Impact and blast loading; Energy absorbing issues; Interaction between computational; and experimental results; Aeronautical and aerospace applications; Response of reinforce concrete under impact; Response of building facades to blast; Seismic behaviour; Structural crashworthiness; Industrial accidents and explosions; Hazard mitigation and assessment; Active protection and security; Tunnel and underground; structures protection; Dynamic analysis of composite structures; Design against failure; Damage limitation.
Download or read book Understanding the Tensile Properties of Concrete written by Jaap Weerheijm and published by Elsevier. This book was released on 2024-03-01 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: The response of concrete under tensile loading is crucial for most applications because concrete is much weaker in tension than in compression. Understanding the response mechanisms of concrete under tensile conditions is therefore key to understanding and using concrete in structural applications. Understanding the Tensile Properties of Concrete Second Edition summarises key recent research in this important subject area. After an introduction to concrete, the book is divided into two parts: part one on static response and part two on dynamic response. Part one starts with a summary chapter on the most important parameters that affect the tensile response of concrete. Chapters show how multi scale modelling is used to relate concrete composition to tensile properties. Part two focuses on dynamic response and starts with an introduction to the different regimes of dynamic loading, ranging from the low frequency loading by wind or earthquakes up to the extreme dynamic conditions due to explosions and ballistic impacts. Following chapters review dynamic testing techniques and devices that deal with the various regimes of dynamic loading. Later chapters highlight the dynamic behaviour of concrete from different viewpoints, and the book ends with a chapter on practical examples of how detailed knowledge on tensile properties is used by engineers in structural applications. Drawing on the work of some of the leading experts in the field, the book is fully updated and will be a valuable reference for civil and structural engineers as well as those researching this important material.

Download or read book Time Effects in Concrete Structures written by R. I. Gilbert and published by Elsevier Publishing Company. This book was released on 1988 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: The inability of designers of concrete structures to recognize and quantify the non-linear effects of cracking, creep and shrinkage is a common cause of serviceability failure. Such failures include excessive deflection, camber and/or shortening of members and excessive cracking which may cause aesthetic or durability problems. This book provides practising engineers with practical and usable techniques for predicting the non-linear effects of creep and shrinkage on the in-service behaviour of concrete structures. Both cracked and uncracked reinforced, prestressed, and composite members subjected to sustained loads or sustained deformations are considered. Analytical procedures are developed for the calculation of instantaneous and time-dependent stresses and deformations on cross-sections in both simple and continuous members. Numerous self-contained worked examples which clearly illustrate the analytical procedures are included. A wide variety of practical situations is considered. Listings of microcomputer programs for a number of the analyses are also presented.
Download or read book Response of Concrete Elements with Varying Compressive Strength to Impact by Fragments with Different Aspect Ratios written by Jared Lee Brown and published by . This book was released on 2020 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concrete is among the most common materials utilized to construct protective elements in hardened structures. Subsequently, understanding how a concrete member will respond to explosively driven fragment or projectile impact is critical to the protective design process. Explosively driven fragments can have many different shapes and sizes depending on the event that resulted in their creation. These geometric variations can include a high-aspect, or width to thickness, ratio; however, impact from fragments with elevated aspect ratios on hardened concrete has not been extensively studied. Therefore, reinforced concrete specimens were subjected to impact from fragments with different aspect ratios to illustrate and quantify the effect of fragment characteristics, protective element features, and experimental target size on local impact performance. A novel experimental technique was developed to allow for high-aspect ratio fragment impact on concrete slabs to be evaluated. The same concrete materials were also impacted with lower aspect ratio fragments for comparative purposes. Data collected from these two experimental series were utilized to analyze the effects of compressive strength, thickness, and fiber reinforcement on impact performance. The accuracy of existing penetration and spall prediction methodologies were evaluated for both fragment types. The kinetic energy required to cause reinforced concrete to present a breached condition due to the high-aspect ratio fragment was also analyzed. Modifications were made to existing contact charge equations to account for differences between the contact charge energy required to cause a breach condition and that required from fragment impact to produce a breach condition. The breach envelope defined by these relationships was further evaluated using a computational model calibrated specifically for this impact scenario. Finally, the effect of impact specimen geometry and confinement type on target performance was numerically evaluated. Artificial and inertial confinement were examined through varying target diameter to projectile diameter ratio with and without artificial circumferential confinement. Given the minimal data associated with local effects of high-aspect ratio fragment impact and the many factors that can influence concrete impact resistance, the information and relationships learned along with the analysis techniques developed herein can be utilized to improve the state of the art of protective design.
