【摘要】 通过动力时程分析,考虑了滑移隔震结构在双向地面运动作用下摩擦力的相互作用对滑移位移的影响,研究了重要参数变化情况下的摩擦力双向相互作用效应.研究表明,摩擦力的相互作用对隔震层滑移位移的影响较大,而对上部结构加速度的响应影响相对较小.所以,如果忽略摩擦力的双向相互作用效应,将导致低估隔震层滑移位移和高估上部结构的加速度.更多还原

【Abstract】 Transient dynamic analysis is used to study the response of sliding displacement of sliding structure to bidirectional ground motion. Circular interaction between the frictional forces is considered. Important parameters are changed to investigate the effect of interaction between the frictional forces. Numerical results show that the response of sliding displacement is influenced significantly by the interaction of frictional forces, but the acceleration of superstructure is different. So the sliding displacement may be underestimated and the acceleration of superstructure may be overrated if the bidirectional interaction of frictional forces is neglected.更多还原
