高层建筑混合连肢墙体系的抗震性能

首先介绍了混合连肢墙体系的产生背景和特点,然后给出了该体系在整体结构和节点性能等方面的研究现状。在总结已有研究成果的基础上,指出了目前研究存在的不足和需要进一步解决的问题,并提出了一种新型钢梁柱焊接连接形式的混合连肢墙体系—含型钢边缘构件的混合连肢墙体系,具有构造简单、施工方便的特点。初步研究结果表明,该种新型连接形式滞回曲线饱满,强度和刚度退化缓慢,具有优良的抗震性能,是混合连肢墙体系值得研究的一个方面。最后给出了这种新型体系的研究内容和需要考虑的主要影响因素。

Seismic Behavior of Hybrid Coupled Wall System in High-Rise Buildings

The background of hybrid coupled wall system(HCWs)stemmed from and its characteristics were presented firstly in this paper.Then state-of-the-art of the research work was introduced.Based on the current achievements,the defect of present work and the problems needing further study were pointed out,and a new kind of welded beam to column connection details of HCWs with steel boundary element in shear walls was proposed,which was simple in details and in construction.Preliminary study showed that the hysteretic curves of this new kind of HCWS were stable and plump,with little degradation in strength and stiffness.So this kind of HCWs had perfect aseismic behaviors and was valuable to study further.At last,the orientation and main influencing factors for future study were suggested.
