非抗震楼层框架梁钢筋和抗震楼层框架梁钢筋有什么区别? - 工程施工 - 项目管理 - 氿上知道

满意答案
在03G101-1中,楼层框架梁纵筋构造分一二级结构抗震等级、三四级结构抗震等级两种,二者的确没有区别,可能会在下一次修版时合并。
03G101-1修编初稿和中稿的一、二级抗震等级与三、四级是有区别的,其主要区别是将35页右上角的构造规定用于一、二抗震等级。后经校对、审核、评审与再思考后,感到时机尚未成熟,需要再做一些前期工作来创造彻底改变这种传统做法的条件。现阶段先把该构造放到35页的共用构造中,观察一下我国结构施工界对其反应。
03G101-1定稿保留这个样子,考虑到一是不影响使用,二是为修版保留可能需要的空间。
我国结构施工的传统做法是将两边(等高)梁的下部筋并排锚入柱节点中,这是发达国家已经废弃的做法。混凝土里并排紧挨着的两根钢筋,存在一条线状通直内缝,当受力时,这条内缝就可能发展成破坏裂缝。
