摘要
某异型截面工程采用扣件式钢管满堂支架进行混凝土浇筑施工,通过有限元软件对该结构进行数值分析,明确该结构各部位受力状况,以指导现场满堂支架结构材料选择、架体搭设及结构加固。研究结果表明,该结构两侧模板,两个支撑点间的圆弧中间处,位移和受力最大。同时随着面板厚度的增加,满堂支架结构最大变形和合应力逐渐减小。
A special-shaped section project employs the fastener type steel pipe full-hall bracket for concrete pouring construction. The stress status of each part of the structure was clarified by numerical analysis to guide the selection of the material of the full chamber bracket, the erection of the frame, and the structural reinforcement. The results show that the displacement and stress are the largest at the middle of the arc between the two support points of the formwork on both sides of the full-hall bracket. The influence of the change of panel thickness on the structure of the full-hall bracket is analyzed. The maximum deformation and stress decrease with the increase of panel thickness.
