摘要
对隔板贯通箱形柱-箱形梁+H形钢梁异型节点试验试件进行了数值模拟分析,对比研究了折线扩大头隔板贯通箱形柱-翼缘削弱箱形梁与H形钢梁异型节点和基本型异型节点在强震下的破坏模式、断裂风险区、节点区应变演化规律.结果表明,贯通隔板折线扩大头区形成塑性铰,节点域应变集中在上核心区.
The numerical simulation analysis of steel box column and steel box beam and H-section steel beam with diaphragm-through irregular joints is carried out.Failure modes under strong earthquake,fracture risk area and strain evolution law of the joint zone of linear enlarged diaphragm-through irregular joints of steel box column and steel box beam with reduced flanges and H-section steel beam and basic specimen with irregular joints were studied and compared.Results show that linear enlarged diaphragmthrough areas come into being plastic hinges,and the node domain strain is concentrated in the upper core region.
