Dynamic Behavior of Concrete and Seismic Engineering
While the static behavior of concrete has been the subject of numerous works, the same cannot be said for the dynamic behavior. This book sets out to remedy this situation: it begins by presenting the most frequently used experimental techniques in the study of the dynamic behavior of concrete, then continues by examining seismicity and seismic behavior, soil behavior, models of concrete structures subject to seismic activity, seismic calculation methods of structures, and paraseismic engineering.
Dynamic Behavior of Concrete Structures
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.
Behavior of Concrete and Seismic Engineering
The design of concrete structures to endure extreme loading conditions from blast or projectile penetration entails the characterization of the material behavior under pertinent conditions and material models that can be used computationally for simulation and analysis. The lack of data and such constitutive models for concrete has posed a significant challenge to structure designers and material engineers. Concrete is a two-phase composite comprising mortar and aggregate. The aggregate serves as reinforcement and upsurges the effective strength and toughness of the overall composite. In recent years, the vibration of cracked structures subjected to dynamic loads has attracted more and more attentions of researchers, and many methods for analyzing the vibration were proposed. Dynamic Behavior of Concrete and Seismic Engineering covers experimental techniques in the study of the dynamic behavior of concrete, examines seismicity and seismic behavior, soil behavior, models of concrete structures subject to seismic activity. This book is intended to estimate the failure mechanism, hysteresis loops, displacement ductility, deterioration of strength and stiffness and energy dissipation of recycled concrete frames under low-reversed cyclic loading as well as the influence of different vertical loading. The nonlinear dynamic behavior of the pre-stressed concrete bridge with such a switching crack subjected to moving trains is investigated. Pre-stressed concrete bridges have found wide applications in railway engineering in recent years. Various studies over the last decade have shown that a structure with such cracks exhibits nonlinear dynamic behavior, and its safety and serviceability are seriously affected. So it is essential to study the vibration of the pre-stressed concrete bridge with such cracks under moving trains. This book is aimed at discovering the dynamic properties of concrete and cement-paste specimens representing the structural material and its adhesive component, and attempts to provide a modest characterization of the physical behavior of these materials on a macroscopic basis.
