摘要
传统的抗震设计方法基本上是增强结构的承载力以抵抗地震作用,对温度应力基本上则是采取释放的措施。根据空冷凝汽器支架结构温度荷载的特点,设计了3种温度计算工况,采用SAP程序计算了空冷支架结构温度效应,给出了结构构件内力变化范围及规律。为了协调温度与地震作用的矛盾,提出了3种设计对策,这些对策都既能释放温度应力,又能耗散地震能量,从而减少结构及其上部设备的破坏。
Conventional seismic design needs strengthening bearing capacity of structures to resist the earthquake action,and needs reducing construction member s constraint to release temperature stress.According to the characteristics of different temperature actions,three calculating temperature cases are designed.SAP2000 code is used to calculate the temperature effects of the support structure system of air-cooled condenser,and then the scope and distribution of internal force or stress of each kind component are...
