【摘要】 对在E-Defense振动台上进行试验的5层带油阻尼器的钢框架结构进行了数值计算模拟,其中油阻尼器的等效刚度由阻尼器的内部刚度和支撑刚度组成,计算模型采用麦克斯威尔模型。对比了数值计算和振动台试验所得的楼层位移、楼层剪力等结果,分析了二者之间的差异,指出了墙板、楼梯、楼屋面板等构件的建模方式是导致差异存在的主要原因。更多还原

【Abstract】 Numerical investigation of a five-story steel frame with oil damper undergoing shaking table test in E-Defense was performed.The Maxwell model was employed for simulation of oil damper which consists of internal stiffness and brace stiffness.Floor drift,floor shear force and other results of numerical investigation and shaking table test were compared,and difference between them was analyzed and discussed.It is concluded that the modeling method of wall panel,slope slab of staircase,floor diaphragm are the primary sources of the difference.更多还原
