摘要

本文研究沿高度变刚度混凝土灌芯纤维石膏墙板结构(以下简称复合墙板结构)在水平荷载作用下的受力机理,建立简化计算模型,推导出了复合墙板结构的受力破坏路径,并建立了各阶段内力计算方法及计算公式。通过实例计算,得到沿高度均匀结构以及非均匀结构在水平荷载情况作用下位移的曲线与非均匀结构的受力破坏路径。结果表明,沿高度适当改变灌芯方式,侧移曲线更趋合理;各区段结构破坏路径均是石膏板先开裂且先达到极限状态。
This paper investigates the stress mechanism of concrete-filled fiber-reinforced gypsum plasterboard with variable stiffness along the height under horizontal forces and sets up its simplified calculation model.In the analysis,the stress fracture course of composite wall plate was deduced and the calculation method and formula with different sections was derived.The displacement curve of uniform and non-uniform structures along the height under horizontal forces was gained and the stress fracture course of non-uniform structure was obtained.The results show that the lateral displacement curve becomes more reasonable with changing the concrete-filled ways along the height and the fracture course of different sections is fiber plasterboard's cracking and getting into its limit state firstly.
