摘要
本文建议对２０层以内的高层钢筋混凝土建筑中常用的框架－剪力墙抗震体系以框－桥架结构抗震体系代替。本课题对该体系进行了１：４模型的计算机－作动器联机系统拟动力试验；文中分析了这类新型抗震体系在地震动作用下的破坏机理和动力特征；提出了“强柱－中梁－弱腹杆”的设计原则。试验证明框－桁架体系具有良好的抗震性能。
This paper introduces two 1/4 scale model tests of frame-truss structural system. The pseudo -dynamic experimental results show that the new structural system could provide a good aseismic capacity.Based on the analysis of the failure mechanism and dynamic characteristics of the test models,a design principle known as 'strong column - medium beam - weak web member' hasbeen proposed. It is suggested to use this aseismic structural system instead of the commonly used frame-shear wall system for highrise reinforced concrete buildings not higher than 20 stories.
