Combined seismic isolation design method under pulse type seismic action
The invention discloses a combined seismic isolation design method under the action of a pulse type earthquake, and belongs to the technical field of damping structure design. The design method in the prior art cannot completely solve the problem of a buffer anti-falling beam device added under the action of pulse type earthquake action or a built bridge. According to the method, a seismic mitigation and isolation support and a buffering anti-falling beam device are designed separately, independence of the seismic mitigation and isolation support and the buffering anti-falling beam device is guaranteed, and the seismic mitigation and isolation support and the buffering anti-falling beam device have design correlation in function on the basis of independent design due to the fact that deformation of the seismic mitigation and isolation support and the buffering anti-falling beam device is caused by displacement of an upper structure. The shock absorption and isolation support and the buffering anti-falling beam device are designed separately, independence of all the parts is guaranteed, installation of the combined shock isolation device is facilitated, and a reasonable basis is provided for supplementary installation of the anti-falling beam device for a built bridge.
本发明公开了一种脉冲型地震作用下组合隔震设计方法，属于减震结构设计技术领域。针对在脉冲型地震动作用下或已建成桥梁补增缓冲防落梁装置，现有技术中的设计方法并不能完全的解决上述问题。该方法将减隔震支座与缓冲防落梁装置分开设计，保证减隔震支座与缓冲防落梁装置的独立性，又通过减隔震支座与缓冲防落梁的变形是由上部结构的位移引起，使两个部分在独立设计的基础上在功能上具有设计的相关性。本发明将减隔震支座与缓冲防落梁装置分开设计，保证各个部分的独立性，便于组合隔震装置安装，且对于已建成桥梁进行补装防落梁装置时提供了合理依据。
