引言《高层民用建筑设计防火规范》(GBJ45—82)(简称高规),于1983年6月1日开始试行,从此我国高层民用建筑防火设计开始有章可循,有法可依。但由于高层建筑发展迅速,在高层建筑防大设计中不断地涌现出新问题、新情况有待解决。如建筑高度超过100m 的高层建筑的防火设计,高层建筑采用玻璃幕墙、中庭、自动电梯、剪刀楼梯时的防火设计,复合防火卷帘、防烟挡板在高层建筑工程中的应用等等。客观形势要求高规应进
Introduction “Fire Code for Design of High-rise Civil Buildings” (GBJ45-82) (abbreviated as GAO) was put into trial on June 1, 1983, and fire prevention design of high-rise civil buildings in our country began to be followed in accordance with the law. However, due to the rapid development of high-rise buildings, new problems continue to emerge in the anti-grand design of high-rise buildings. The new situation remains to be solved. For instance, the fire protection design of high-rise buildings with a building height of more than 100m, the fire protection design of high-rise buildings with glass curtain walls, atriums, automatic elevators and scissors staircases, the application of composite fire shutter and smoke baffle in high-rise building projects. The objective situation calls for a high degree of compliance
