摘要
为了研究混凝土灌芯纤维石膏墙板(以下简称复合墙板)在荷载作用下石膏墙板与芯柱受力发展过程、受力体系的演变过程及承载力,该文依据复合墙板的构成特点,将石膏墙板与由芯柱和圈梁构成的框架(以下简称框架)分开,分别确定力与位移的关系并用匀质链杆相连,建立计算简图。再依据石膏墙板与框架的高宽比不同其变形特点不同,分别确定力与位移的关系,以变形协调关系为理论基础推导出了高宽比不同时复合墙板的受力破坏路径,及各阶段的内力计算方法及计算公式。计算结果表明:该文提供的方法与试验结果吻合较好。
The paper investigates the loading performance and the ultimate capacity of concrete frames with fiber plasterboard. In the analysis, the plasterboard and the frames consisting of concrete core and ring beam are assumed to be connected by isotropic chain-poles. Then, the relations between load and displacement are determined corresponding to different Height-Width ratios. Moreover, the damage procedures are developed based on deformation compatibility, the calculation method and internal force formulas are derived at different damage stages. The calculated results agree well with the experimental results.
