"备注：1.混凝土强度等级不大于C25时，表中保护层厚度增加5mm。当表中出现“****”或“#VALUE"",表示该种边缘构件在规范中不存在。",,,,,,,,,,,,,,,,

2.采用400MPa钢筋时，混凝土强度等级不得低于C25；采用500MPa钢筋时，混凝土强度等级不得低于C30,,,,,,,,,,,,,,,,

3.《混凝土规范送审稿》用作受剪、受扭、受冲切承载力计算的箍筋，抗拉强度设计值不应大于360N/mm2。(高规送审稿：不再受360N/mm2限制）（对剪力墙边缘构件，尽管不用其抗剪（靠水平筋），但个人认为还是按箍筋要求为宜）。,,,,,,,,,,,,,,,,

4.部分框支抗震墙结构的抗震墙，应在底部加强部位及相邻的上一层设置约束边缘构件。,,,,,,,,,,,,,,,,

5.保留二级抗震（老规范），对应轴压比0.3和0.4的情况，以便新老规范过度阶段使用。,,,,,,,,,,,,,,,,

6.非阴影区箍筋：可采用比阴影区箍筋直径小一个型号的钢筋（间距不变），采用环套布置，一般均能满足Zv/2。所以，非阴影区不再计算。,,,,,,,,,,,,,,,,

7.核心区面积：取箍筋内表面计算,,,,,,,,,,,,,,,,
