| 摘 要： | 在建筑结构中,橡胶垫支座往往处于复杂受力状态,为了防止风吸力与水平力作用下出现过大变形,可以在支座中设置限位螺栓.本文对带螺栓孔橡胶垫抗压弹性模量进行了深入分析,提出了形状系数修正方法；对传统的板式橡胶支座进行了改进,在橡胶垫的上、下盖板之间设置了限位条,避免橡胶垫粘结失效的影响；对比分析了不同设计标准中的橡胶垫抗压弹性模量的计算方法,提出了改进建议.最后,对板式橡胶支座的抗压弹性模量、抗剪弹性模量与支座转角进行了试验研究.

| Abstract: | In building structures,laminated rubber bearings are generally in complex stress state.In order to prevent excessive deformation of bearings due to wind suction and horizontal forces,the limited position-bolts set in rubber bearings are recommended.In this paper,the compressive elastic modulus of laminated rubber with bolt-holes are analyzed in detail,and a modified method of old shape-factor-calculation is proposed.Meanwhile,traditional rubber bearings are improved,and stop-strips at the edges of the upper... |
