多层混凝土框架工业厂房震害预测

Seismic Hazard Prediction for Multi-Story RC Frame Structure of a Factory Building

近年来,由于我国地震的频频发生,部分钢筋混土框架结构的严重破坏和倒塌,特别是许多工业厂房,虽然是严格按照国家规范设计建造的,但是在罕遇地震作用下,该类厂房仍然受到了较大的破坏[2]。对单体多层混凝土框架工业厂房震害预测的步骤进行了简述,并结合某开发区一个算例进行了对比分析,针对多层混凝土框架工业厂房的特点,提出抗震设计建议,为抗震设计、加固提供一定的借鉴作用。

In recent years,earthquake occurred frequently in our country,some frame structure of reinforced are severely damaged or even collapsed.Especially multi-storey frame industrial structure,although be designed in strict accordance with the national standard,still be severely damaged in the earthquake.Steps of seismic disaster prediction for a multi-story frame structure building are briefly introduced.A comparative analysis is conducted with a calculated example.Some suggestion are given according to the characteristic of the multi-storey frame structure,It may offer reference for designer.
