| 摘 要： | 对我国生产的直径３００ｍｍ的夹层橡胶隔震支座（铅芯及非铅芯两种类型）进行了长期力学性能及耐火性能试验研究。首先，研究了隔震支座的基本力学性能。其次，对隔震支座频率、温度、压力、大变形等相关性能进行了试验研究。隔震支座的长期性能研究则针对隔震支座在使用期限６０年后（建筑物的寿命通常定为５０年）的力学性能进行了热老化及徐变试验，结果表明隔震支座在使用期限内其力学性能稳定。最后，对隔震支座进行了耐火性能研究。

| Abstract: | The duration and fireproof properties of lead and non-lead rubber bearings are tested. Firstly, basic mechanical characteristics and dependences such as frequency, temperature, com- pression and large shear strain are tested according to the standards published in China. Ageing and creep tests are completed in order to grasp the mechanical properties when rubber bearings have been used for 60 year, it is proved that both two types of rubber bearings have stable properties. Finally, fireproof tests are performed at a similar condition with a true building. |
