一、概述:目前屋架上弦的截面多采用矩形或T形,各有其优缺点。矩形截面与T形截面相比,混凝土用量较多,钢筋用量较少,模板简单,费用也较低,而且可以重叠生产,减少施工场地,因此我们认为矩形截面还是可取的。为了充分发挥矩形截面
I. Overview: Currently the cross section of roof trusses is mostly rectangular or T-shaped, each with its own advantages and disadvantages. Compared with the T-shaped section, the rectangular section has more concrete consumption, less rebar usage, simple formwork, lower cost, and can overlap production and reduce the construction site. Therefore, we believe that the rectangular section is still desirable. To make full use of rectangular section
