| 摘 要： | 为了改善钢筋混凝土核心筒的抗震能力,提出了内藏钢桁架混凝土组合核心简,对2个1/6缩尺的核心筒结构模型进行了低周反复荷载下的抗震性能试验研究,包括1个普通混凝土核心简和1个内藏钢桁架混凝土组合核心筒.在试验的基础上,分析了2个试件的承载力、刚度、延性、滞回特性及耗能能力.试验研究表明,内藏钢桁架混凝土组合核心筒比普通混凝土核心筒抗震能力显著提高.建立了承载力计算模型,计算结果与实测值符合较好. |
| 关 键 词： | 钢筋混凝土 钢桁架 核心筒 抗震性能 |

| Abstract: | To improve the seismic performance of the RC core walls,reinforced concrete composite core walls with concealed steel truss were proposed and systemically investigated.Two 1/6 scale core walls specimens, including a normal reinforced concrete core walls and a reinforced concrete composite core walls with concealed steel truss,were designed.The experimental research on seismic performance under cyclic loading was carried out.The load-carrying capacity,stiffness,ductility,hysteretic behavior and energy dissipation of the core walls were discussed.The test results showed that the seismic performance of core walls was improved greatly by the concealed steel truss.And the calculating results were found to agree well with the actual measured ones. |
| Keywords: | reinforced concrete steel truss core walls seismic performance |
