摘要
在高性能混凝土中掺加矿粉可提高混凝土的工作性和耐久性.目前,国内外对高性能混凝土抗震性能的研究还比较缺乏.基于6根梁的低周反复荷载试验,较为系统地研究了掺矿粉高性能混凝土梁的破坏形态、恢复力模型、变形恢复能力、延性、刚度退化、耗能能力等抗震性能.研究表明,掺矿粉高性能混凝土梁具有优良的抗震性能.
High performance concrete (HPC) is considered as structural concrete in new century. Adding slag powders into HPC can improve workability and durability of concrete. At present, studies on seismic performance of HPC concrete are scarce at home and abroad. Failure pattern, restoring force model, deformation restoring capacity, ductility, rigidity degeneration and energy dissipation of HPC with slag powders are studied systematically based on experiments of 6 beams under low reversed cyclic loading. And studies show that HPC beams mixed with slag powders have good seismic performances.
