灾后重建隔震技术应用
|
摘要
2008年中国汶川地震造成了大量的人员伤亡和工程结构破坏。隔震作为结构控制技术的代表,为保护结构免受地震破坏而已被大量应用于新建工程和现有结构加固改造。首先,对适用于重建的有关隔震系统进行了探讨,提出了采用弹性滑板支座和低面压橡胶支座组成的隔震系统是纯滑移隔震系统的有效完善方案。其次,依据国内、外基岩周期的定义和实际地震记录反应谱在长周期段对应的拟速度幅值恒定的事实,对中国隔震设计反应谱进行了修正。最后,为控制上部结构的塑性反应,提出了系统协调隔震设计思想。
The 2008 Wenchuan earthquake in China has caused significant loss of lives and destroyed a great many civil engineering structures. Seismic isolation,as a typical means of response control technology,has been widely used in both new and existing buildings to protect from the devastating effects of earthquakes. The seismic isolation systems is suited for rebuilding,and the combined system of elastic sliding bearings and rubber bearings with low vertical load is an effective measure to develop the pure sliding isolation technique. According to the period on the bedrock defined by domestic and foreign and the fact that real earthquake spectrum with a uniform velocity portion in the longer-period range,the response spectrum for seismic isolation design is revised. Finally,a system harmonious design method for the plastic response control of super-structure is proposed.
