由于桥梁结构的多样性,对橡胶支座的性能要求也不相同,有些要求橡胶支座以承压为主,有些要求在承压的同时还必须承受剪切变形及转动变形,有的要求橡胶支座具有良好的吸能减震能力。因此,橡胶支座的设计是一个十分复杂、严谨的工作,支座规格系列标准在方便结构工程师的设计选用和厂家生产的同时,也担负了原来应由结构工程师所承担的责任。况且支座规格系列并没有包罗万象,过度的简化和集中使得本应十分丰富的设计形式过于单一。
Due to the diversity of the bridge structure, the performance requirements of the rubber bearings are not the same, some require the rubber bearing to pressure-based, some require the pressure at the same time must also withstand shear deformation and rotational deformation, and some require rubber Support has a good energy absorption capacity. Therefore, the design of the rubber bearing is a very complicated and rigorous work. The series of bearing specifications are also responsible for the structural engineers’ responsibility for the design and manufacturing of the structural engineers. Moreover, the support specification series is not all-encompassing, excessive simplification and concentration makes the design form that should be very rich is too single.
