Author Description

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 co
