摘要
橡胶支座是目前工程中使用最为广泛的支座类型 ,但关于它的特性尚不很清楚。对它的主要性能加以说明 ,尤其是它能转动 ,但不能释放弯矩的性能 ,将直接影响结构分析时的建模 ,关系到计算结果的正确性和结构安全性 。
Rubber bearings are most widely used in Chinese engineering practice nowadags But there is a lot of problems in application of rubber bearings This paper introduces rubber characters and rubber bearings overall At same time this paper points out key matters for attentions:①Rubber bearings can be rotated but can not be released the moment ②Rubber bearings will definitely be aging during their service periods ③Their elastic modular is very low,especialy the horizontal shear modular Therefore under loading the deformation will rather big This paper also introduces the advantages and disadvantages of rubber bearings
