《国际建筑规范》(IBC)将以前版本的重要改进结合在一起,包括限制无防火措施的不燃烧体建造的低中危险等级的商用仓储建筑为2层(有自动喷水灭火系统时为3层)。先前版本允许这类建筑为4层(有自动喷水灭火系统时为5层)。这种变化并不是对生命和财产损失经验的响应,而是试图使2009年版IBC与其最初三个传统典型建筑规范中最严格的要求协调一致。当考虑到规范改变的优点时,需要提出3个问题:(1)最终期望的结果是什么?(2)成功如何判断?(3)通过何种方法来达到成功? The International Building Code (IBC) combines significant improvements from previous versions, including low- and medium-risk commercial storage buildings constructed from non-flammable bodies that limit fire protection to 2 floors (3 for sprinkler systems Floor). The previous version allowed this type of building to be 4 levels (5 levels with a sprinkler system). Rather than responding in response to the loss of life and property, this change seeks to reconcile the 2009 edition of IBC with the most stringent requirements of its first three traditional building codes. When considering the benefits of regulatory change, three questions need to be asked: (1) What is the end-result? (2) How is success judged? (3) How can we achieve success?
