港工钢筋混凝土受弯构件的抗裂度验算,虽然采用了等效换算的方法,使计算简单了许多,但还是需要折算截面、受压区高度、惯性矩等一系列计算,仍较烦琐,对于工字形、T形、倒 T 形截面,计算量则更大。对一钢筋混凝土受弯构件,如果荷载作用下截面承受的弯矩 M 较大,则按正截面强度计
Although the calculation of the crack resistance of flexural members reinforced by Hong Kong workmanship is quite simple and easy with the equivalent conversion method, it still needs to be calculated in a series of calculations such as the section of the compression zone, the height of the compression zone and moment of inertia, For the I-shaped, T-shaped, inverted T-shaped section, the amount of computation is even greater. For a reinforced concrete flexural member, if the load under the section under the load moment M is large, according to the normal section strength meter
