钢筋的混凝土保护层最小厚度的取值,主要取决于构件的耐久性和受力钢筋粘结锚固性能的要求。耐久性的要求是按照构件在50年内能保护混凝土保护层内的钢筋不发生危及结构安全的锈蚀来确定的。而从钢筋粘结锚固角度对混凝土保护层提出的要求是保
The value of the minimum thickness of the reinforced concrete protective layer mainly depends on the durability of the component and the requirements of the bond strength and anchorage performance of the stressed steel bar. The durability requirement is determined according to the corrosion of the steel bars that can protect the concrete protection layer within 50 years without endangering the structural safety. The requirement of the protective layer of concrete from the perspective of reinforcing and bonding of steel bars is
