| 摘 要： | 磷石膏墙体网格式框架作为一种新的结构形式,可利用现行建筑结构设计软件进行工程设计,根据结构在水平荷载作用下顶点侧移相等的原则,建立高层磷石膏墙体网格式框架结构等效为剪力墙结构的墙厚度折算公式,理论计算值和磷石膏墙体网格式框架结构有限元分析结果误差仅0.4%,与等效剪力墙误差8.59%。与等效剪力墙有限元分析结果产生误差是由于未考虑洞口对截面面积和刚度削弱的影响。总的来说,理论计算值和有限元分析结果较吻合,等效剪力墙墙厚度折算公式符合实际,可为实际工程设计提供参考。 |

| Abstract: | Grid frame structure with phosphogypsum as the wall is a new type structure,which can be designed by the existing structure software.The conversion formula of the thickness of the equivalent shear wall is established according to the principle of the same top displacement under horizontal loads.The error between the calculated value and the finite element analysis of grid frame structure with phosphogypsum as the wall is only 0.4%,which is 8.59% as compared with the equivalent shear wall.The error of finite element analysis of the equivalent shear wall is caused by not considering the impact of the hole weakening the cross-sectional area and stiffness.Overall,the theoretical calculation values and finite element analysis results agree well,the conversion formula of equivalent shear wall thickness is consistent with the actual conditions,which may provide a reference for engineering design reference. |
| Keywords: | grid frame structure shear wall finite element horizontal load |
