摘要
为研究钢(S)梁和角钢骨架混凝土(SC)柱组成的框架在荷载作用下的工作性能,进行了一榀1/3比例两跨三层S梁-SC柱组合框架模型在低周反复荷载作用(伪静力)和使用等效单自山度体系输入实际地震加速度记录(拟动力)两种加荷方式下的试验。根据试验结果,文中对组合框架的破坏机制、变形、刚度和延性以及组成构件的工作性能进行了初步分析研究。
In order to investigate the behaviors of composite frame composed of steel beams and steel concrete columns with angle lacings,the pseudo-static tests and pseudo-dynamic carthquake response tests of one third scale two-bay three-story composite frame,conducted as equivalent single degree of freedom sys- tem have been carried out.According to the experimental results,the failure mecha- nism,deformation,rigidity and ductility of the composite frame have preliminarily been analyzed.The working properties of the beams,the columns and the joints in the frame have also been discussed in this paper.
