摘要:
为简化延性耗能节点钢框架结构的数值计算，利用延性耗能节点简化理论模型分别对6层、12层的翼缘削弱型节点钢框架和盖板加强型节点钢框架进行简化，并对框架简化模型和实际框架模型进行模态分析；提取框架结构的前3阶基本周期并计算阻尼比，并对框架结构简化模型和实际模型开展El Centro波和Taft波2种地震波下的动力时程分析，将框架简化模型计算得到的框架基本周期、柱顶位移和柱底剪力时程曲线与实际框架模型的数值计算结果进行对比。结果表明：整体上框架简化模型和实际框架模型的数值计算结果吻合较好，翼缘削弱型节点框架简化模型计算的框架基本周期比实际模型计算值稍小，相对误差在8.5%以内，而盖板加强型节点框架简化模型计算的框架基本周期比实际模型计算值稍大，相对误差在4.0%以内；柱顶位移和柱底剪力时程曲线吻合较好。延性节点简化理论模型用于框架结构动力计算具有极高的计算精度，可有效分析延性节点钢框架结构的抗震性能。
Abstract:
In order to simplify the numerical calculation of steel frame structure with ductile and energy-dissipated connection, 6-layer and 12-layer frame structures with reduced beam section connections and cover-plate reinforced connections were simplified by using simplified theoretical model of ductile and energy-dissipated connection. The modal analyses of simplified frame model and actual frame model were carried out. The first three fundamental periods of structures were obtained and the damping ratio was calculated. The dynamic time-history analyses of simplified frame model and actual frame model under El Centro seismic wave and Taft seismic wave were carried out respectively. The fundamental period of frame, displacement of column top and shearing force time-history curve of column bottom which were gotten from the simplified frame structure models were compared with numerical results of actual frame models. The results show that numerical results of simplified frame model are consistent with those of actual frame model as a whole. The fundamental periods of frame with reduced beam section connections which are acquired from the simplified structure models are smaller than those of actual structure models, and the relative error is within 8.5%. The fundamental periods of frame with cover-plate reinforced connection which are acquired from the simplified frame models are bigger than those of actual structure models, the relative error is within 4.0%. The displacement time-history curve of column top is in good agreement with that of shearing force of column bottom. It has high computational accuracy when the simplified theoretical model of ductile connections are applied to dynamic calculation of frame structure, so it can effectively analyze the seismic performance of steel frame structure with ductile connections.
