摘要
基于结构与地面水平相对位移作为最后防线的防震观点,提出了一种水平面耗能机制的节点构造的设计方案。论证了水平错动面能提高房屋抗震的安全性和经济指标,提出了水平耗能面的设计原则。节点构造方案可以保证错动先于倾覆破坏,设计、施工、材料在传统结构建造的范畴内,还具有可工厂化生产、密封免维护等优点。
Based on the view that the horizontal sliding between the basement and the structure works as the last defence against the earthquake, a model of a device which allows the horizontal sliding to happen has been presented in this paper. It has been verified here that the aseismic safety and the economization could be raised by the horizontal sliding. According to the structure of the device presented here, the sliding would happens surely earlier than the building＇ s collapse in earthquake, and this device can be produced in plants. By the way, it would be proofed, so the maintenance is not needed.
