摘要:
连接单元与主体结构的碰撞效应是引起连体结构损坏和塌落的重要原因,以西安站改东配楼为背景,采用Kelvin单元对该不规则复杂连体结构进行了碰撞效应分析,研究了碰撞效应对桁架支座位移及碰撞力的影响,分析桁架及关键构件的内力、位移及塑性铰出铰机制,讨论了接触刚度和初始间隙对碰撞效应的影响规律。结果表明:强震作用下,复杂连体结构极易产生碰撞,其对桁架、框架梁柱的内力和位移有显著放大作用,使连接体的塑性铰明显增多,均进入"立即使用"状态。建议该连体结构碰撞效应分析的接触刚度取大于主框架梁轴向刚度的数值5×106 kN/m;初始间隙取值大于0.2 m时,支座处的碰撞力消失。
Abstract:
Collision effect connection unit and the main body structure is an important cause of the damage and collapse of the structure, based on the background of the Xi’an railway station, the Kelvin unit of the irregular complex connected structures were collision effect analysis, studied the effect of the collision on the truss support displacement and collision force, internal force analysis, key component of the displacement of truss and plastic hinge mechanism, the influence of contact stiffness and initial gap on the impact effect of discussion. The results show that:under the action of super seismic intensity, complex connected structure are easy to collide, which significantly amplifies the internal force and displacement of truss, frame beam and column, makes the plastic hinge of connections increase obviously, all of them enter the "immediate use" state. It is suggested that the contact stiffness of the connected structure is greater than that of the main frame beam’s axial stiffness with 5×106 kN/m. When the initial gap value is greater than 0.2 m, the impact force of the support will disappear.
