Dynamic Mechanical Behaviors and Constitutive Model of Roller Compacted Concrete (eBook)

This book systematically illustrates the dynamic mechanical behaviors and discusses the fundamentals of the constitutive modeling of roller-compacted concrete (RCC), influenced by the construction technique and mix design. Four typical problems are analyzed using laboratory tests, numerical simulation and theoretical analysis, i.e., to illustrate the special dynamic mechanical behaviors of RCC, to reveal the dynamic size-dependence of mechanical properties, to discuss the aggregate size effect on dynamic mechanical properties, and to modify the dynamic constitutive model for RCC. Generally, the constitutive modeling of RCC needs a comprehensive understanding of dynamic size-dependence and aggregate size effect of concrete that coupled with the strain-rate sensitivity. So that, readers can master the modified dynamic constitutive model of RCC to analyze and solve the problems in blast-resistance analysis and protective design of RCC dams.

This book can be used as a postgraduate textbook for civil and hydraulic engineering in colleges and universities, and as an elective course for senior undergraduates. It can also be used as a reference for relevant professional scientific researchers and engineers in field of protective design of concrete structures.

Professor Sherong Zhang graduated from Tianjin University, China, in 1982 for B.Sc. He obtained his M.Sc. and Ph.D. in 1993 and 2004, respectively. His research interests include the static and dynamic analysis of hydraulic structures, risk and reliability of engineering structures, and stability of underground caverns and slopes. Prof. Zhang undertook or participated in more than ten national and provincial fund projects. He has published more than 200 academic papers and 5 academic monographs and textbooks. He has won many honors and awards, such as 'National Science and Technology Progress Award' four times and various provincial and ministerial science and technology progress awards eight times.
