从多次地震表明,工业厂房没有抗震设防,一旦发生地震就必然带来不同程度的破坏和损失。所以,对已有厂房进行妥善加固,对新建厂房在设计中作抗震设防,都是非常必要的。通过近几年来对天津冶金工业厂房抗震加固工作的实践,谈几点体会。一、厂房建筑抗震加固应以防为主 1.对已有厂房应力争做好抗震加固实践证明,厂房建筑只要进行了加固,不论这种加固是通过了抗裂度验算还是没有验算,其结果都能起到不同程度的抗震作用,从
From several earthquakes, it has been shown that industrial plants do not have seismic fortification, and that once an earthquake occurs, it will inevitably bring about different levels of damage and losses. Therefore, it is very necessary to properly reinforce the existing factory buildings and to provide earthquake protection for the newly-built factory buildings. Through the practice of seismic strengthening of Tianjin metallurgical industrial plant in recent years, I have discussed a few experiences. 1. The earthquake resistance of the plant building should be prevented by the main 1. The practice of strengthening the earthquake resistance of existing plant buildings proves that if the plant building is reinforced, no matter whether it is cracked or not checked, the result is Can play a different degree of earthquake resistance, from
