活性粉末混凝土柱的抗震性能试验研究

活性粉末混凝土 (ReactivePowderConcrete ,简称RPC)是一种具有超高性能和超高强度的水泥基复合材料。本文首先论述了这一材料应用于结构抗震领域中的潜力 ,然后通过 4个小比例RPC矩形截面柱的拟静力试验 ,研究了RPC配筋柱的延性性能、滞回曲线及其破坏机理 ,分析了配箍率对RPC配筋柱延性的影响。

Experimental Study on Seismic Performance of Reactive Powder Concrete Columns

Reactive powder concrete (RPC) is a super-high strength cement-based composite material with advanced mechanical and superior physical property. Potential applications of RPC in earthquake engineering were discussed. Cyclic tests of four small-scale RPC columns with rectangular cross-section were carried out to study seismic performance of RPC structures. Ductility capacity, hysteretic model and failure mechanism of RPC column were studied. The effect of lateral reinforcement amount on ductility of column was investigated.
