模板支架承受的倾斜结构自重计算方法研究
|
摘要
研究了倾斜结构自重传递至模板支架的荷载计算方法。本文提出倾斜结构自重可按力的分解原则分配至模板支架的假设,并给出计算公式。对比有限元分析的计算值和公式计算的理论值,公式理论值与有限元分析计算值的比值接近于1,表明前述假设成立。通过柬埔寨体育场项目的模板支架的设计计算,演示荷载分配的具体方法。
This article focus on calculation method of dead load on formwork transferred from inclined structure.This article hypothesizes that decomposition principle can be apply to calculate dead load transferred from inclined structure and proposes calculation formula.Compare theoretical value from formula and calculation value from finite element analysis, theoretical value is equal to calculation value, which means the hypothesis is true. Through calculating formwork of Morodok Techo National Stadium in the kingdom of Cambodia, demonstrate how to apply the calculation method.
