摘要
系统地对公路桥梁板式橡胶支座在容许荷载作用下进行了试验研究,根据橡胶支座内部橡胶与钢板结合部位的应力集中特点,分析了橡胶支座裂纹萌生的扩展情况,初步建立了简单的损伤模型,并根据该模型预测了橡胶支座损伤发展的趋势。
This paper conducted experiment research on plate type rubber bearing under allowable load systematically, analyzed the crack extension of rubber bearing according to the characteristics of stress concentration from the part that combined rubber with steel plate. The simple damage module is also build up and the development trend of bearing damage is predicted.
