一、概述T形截面受弯构件正截面承载能力计算方法,适用于多种截面形状的构件,因为在受弯承载能力计算时,假定拉区砼不参加工作,所以有许多外形虽然不是 T 形截面,但可按 T 形截面计算,例如 I 形截面。还有些截面形状,虽然不是 T 形和 I 形截面,但是可以折算成 T 形和 I 形截面,例如多孔板可以折算成 I 形截面,肋形板可以折算成 T 形截面,不过在折算时,考虑到翼板与肋的共同
1. Outline the calculation method for the normal section load-bearing capacity of a T-section flexural member. It is applicable to members of various cross-sectional shapes. Because the bending zone does not participate in the work when calculating the flexural load capacity, many shapes are not T-shaped. , but it can be calculated as a T-section, such as an I-section. Some cross-sectional shapes, although not T-shaped and I-shaped, can be converted into T-shaped and I-shaped cross-sections. For example, a perforated plate can be converted into an I-shaped cross-section, and a ribbed plate can be converted into a T-shaped cross-section. However, when converted, Considering that the wings and ribs are common
