钢管混凝土叠合柱边框组合核心筒抗震性能试验研究
|
摘要
为了比较带钢管混凝土叠合柱边框组合核心筒与带钢管混凝土边框组合核心筒的抗震性能,进行了1个钢管混凝土叠合柱边框组合核心筒模型和1个钢管混凝土柱边框组合核心筒模型的低周反复荷载试验研究,2个模型均按1/6缩尺.在试验基础上,分析比较了2个核心筒的承载力、延性、滞回特性、刚度及其衰减过程、耗能能力和破坏特征.研究表明,钢管混凝土叠合柱边框组合核心筒比钢管混凝土柱边框组合核心筒的抗震性能显著提高;承载力简化计算模型的计算结果与实测结果符合较好.
The cyclic tests are performed in order to compare the seismic behavior of two 1/6 scale composite core walls with different columns,one with concrete filled steel tube columns and the other with steel tube-reinforced concrete columns.Based on the experiment,load-carrying capacity,ductility,hysteretic property,stiffness and degradation,energy dissipation and damage characteristics of the two specimens are compared.It is shown that the seismic behavior of the core walls with steel tube-reinforced concrete columns is better than those with concrete filled steel tube columns.The mechanical model for calculating load-carrying capacity of the new RC composite core walls is proposed.And the calculating results agreed well with the results from the experiments.
