摘要:
利用一套简单可靠的加载装置,对6根510 mm×510 mm的高强混凝土柱足尺试件进行了固定轴力下的水平往复加载试验.试验参数为塑性铰区的箍筋间隔、强度及轴压比等.将试验结果与理论计算结果进行了对比.研究表明高强混凝土柱的抗震延性受轴压比及配箍率影响较大,而现行的美国混凝土设计规范ACI318—99抗震规范的箍筋设计公式对轴压比的影响考虑不足.本文根据试验提出了一个以柱端相对位移或延性为性能指标的配箍设计公式.
Abstract:
Utilizing a set of simple and reliable loading system,six 510 mm×510 mm full-scale high-strength concrete columns with compressive strength of more than 63 MPa were tested under cyclic lateral force and a constant axial load. The main experimental parameters were the axial load level and the transverse reinforcement detail. The experimental results were compared with the analytical results. It is shown that the seismic ductility of high-strength concrete columns is significantly influenced by the axial load ratio and the amount of transverse reinforcement.An equation for transverse reinforcement design is suggested based on performance demands.
