本文通过4个矩形内框和5个菱形内框消能柱间支撑以及2个柱间交叉支撑模型的试验研究,结合国内外有关试验分析,说明消能支撑的延性系数μ和阻尼比ζ都比交叉支撑好得多,矩形内框又比菱形内框消能支撑效果更好些。从提高厂房的纵向抗震性能来说,采用消能支撑是有效的。消能支撑柱列的内力和变形采用杆件变刚度的电算方法是可行的。为了设计应用方便,文中提出了消能支撑杆件内力的简化计算方法。
In this paper, the experimental study of four rectangular inner frames and five diamond-shaped inner frame energy dissipating column supports and two inter-column cross-bracing models are carried out. Combined with relevant domestic and foreign experimental analysis, the ductility coefficient μ and the damping ratio of the energy dissipation support are shown. It is much better than the cross-support. The rectangular inner frame is better than the diamond-shaped inner frame energy dissipation support. From the standpoint of improving the longitudinal seismic performance of the plant, the use of energy dissipation support is effective. The internal forces and deformations of the energy dissipation support column columns are feasible using the electrical calculation method of the stiffness of the rod member. For the convenience of design and application, a simplified calculation method for the internal force of the energy dissipation support member is proposed.
