港口工程钢筋混凝土梁受弯时的强度计算、其正截面强度一般采用破损阶段法,其斜截面强度则沿用许可应力法验算其主拉应力。显然,同一构件采用两种不同应力阶段为基础进行强度计算是不合理的。为此,交通部《混凝土和钢筋混凝土规范》修订组(以下简称规范组)根据港口工程钢筋混凝土结构构 For strength calculation of flexural strength of port engineering reinforced concrete beam, its normal section strength is usually broken stage method, while its oblique section strength is calculated by allowable stress method. Obviously, it is unreasonable to calculate the strength of the same member based on two different stress stages. To this end, the Ministry of Communications “Concrete and Reinforced Concrete Code” revision group (hereinafter referred to as the specification group) according to the port works reinforced concrete structure
