活性粉末混凝土力学性能及基本构件设计理论研究进展

PROGRESS IN MECHANIC PROPERTY AND DESIGN THEORY OF ELEMENTARY STRUTURE OF REACTIVE POWDER CONCRETE(RPC)

对活性粉末混凝土(RPC)的基本力学性能的研究发展与基本构件设计理论的研究成果做了较为全面地评述.在分析研究活性粉末混凝土的工程与理论意义的基础上,先后介绍了RPC试件的基本力学性能、各组成原材料含量对试件力学性能的影响、动态载荷作用下的力学性能、RPC基本构件的设计理论等.对研究中的不足与亟待解决的问题做了综合分析,RPC基本构件设计理论与框架结构的破坏特性研究是未来一段时期内较为有意义的研究方向.

In the light of achievements from theories, numerical modeling and experiments, the present paper carries out a comparatively detail review on the research progress in basic mechanical characteristics and design theory of elementary structure of RPC. On the basis of analyzing the engineering and theoretical significances of the study on reactive powder concrete, the author presents basic mechanical characteristics of RPC specimen, influences of different components in concrete on mechanic characteristics of specimen, mechanical properties under dynamic loading, design theory of RPC elementary structure, and probes into flaw and problems urgently needed to solve. It is indicated that the design theory of RPC elementary structure and failure characteristics of RPC frame will remain significant research topics in a long span of future.
