1.前言随着大型电站的发展,锅炉容量急剧增加,锅炉高度也必然相应提高,特别像日本这样的多地震的国家对防震这一问题更加重视起来了。以往,在锅炉和锅炉钢架的防震设计方法上并不是十分明确的,都是按建筑标准法中的水平震度法。但是对于锅炉这样 1. Introduction With the development of large-scale power plants, the capacity of boilers has increased dramatically, and the height of boilers will inevitably increase accordingly. In particular, countries with multiple earthquakes such as Japan have paid more attention to the issue of earthquake protection. In the past, the seismic design methods for boilers and boiler steel frames were not very clear, and they were all based on the horizontal seismic method in the Building Standards Act. But for boilers like this
