传统风格建筑钢-混凝土双枋-柱节点力学性能分析

Mechanical Properties Analysis on Chinese Traditional Style Architecture for Di-Lintel-Column Joint

目的研究传统风格建筑双枋-柱节点的破坏特征及力学特性。方法设计了3个典型传统风格建筑双枋-柱节点试件及1个单枋-柱节点试件,对其施加正弦波动力循环荷载,对其滞回曲线、骨架曲线、承载力及延性等进行分析。结果将传统风格建筑与黏滞阻尼器相结合,可显著提升传统风格建筑双枋-柱节点试件的抗倒塌能力及承载力,延性性能提高了12.7%,承载力提高了15.7%;双枋-柱节点试件承载能力及延性均高于单枋-柱节点。结论在雀替位置处合理设置黏滞阻尼器可显著改善传统风格建筑双枋-柱节点试件的力学性能。

In order to research the failure characteristic and mechanical properties of typical di-lintel column joints,3 specimens of di-lintel-column joints in Chinese traditional style architecture and 1 lintel-column joint were designed and tested under wine wave dynamic cycle load.The mechanical performances such as hysteretic characteristics,load capacity and ductility have been analyzed.Results indicate that the collapse resistance and bearing capacity of Chinese traditional style architecture with viscous damper are greatly improved.The displacement ductility is increased by 12.7%,the carrying capacity is increased by 15.7%.The bearing capacity and ductility of the di-lintel-column joints are higher than the lintel-column joint.The mechanical properties of Chinese traditional style architecture were improved significantly after viscous dampers were placed at the sparrow position.
