自密实高性能混凝土结构力学性能

通过梁的纯弯试验和柱的低周反复荷载试验,研究了自密实高性能混凝土构件的抗弯性能和抗震性能,主要分析了破坏形态、特征荷载、延性性能、刚度退化以及耗能能力.结果表明:自密实混凝土构件具有与普通混凝土构件相近的抗弯、抗震性能,可以参照普通混凝土设计规范进行设计.试验结果为自密实高性能混凝土的推广提供了依据.

Mechanical Property of Self-compacting High Performance Concrete Structure

In this paper,it studies the bending performance of self-compacting high performance concrete beam under the concentrative loads and the seismic performance of SCC column under the low reversed cyclic loads,emphasizes on analyzing the failure pattern,characteristic loads,ductile performance,stiffness degradation and energy dissipation capacity.The study shows that the bending performance and seismic performance of the selfcompacting high performance concrete members are similar to those normal concrete memb...
