某项目装配式梁式剪刀楼梯构件有限元分析

Finite Element Analysis of Assembly Beam Staircase of A Project

装配式梁式剪刀楼梯构件,因其能大幅减轻大跨度剪刀楼梯的预制梯段重量,在目前装配式建筑中具有较为明显的优点。以某工程为例,利用有限元软件ABAQUS对装配式梁式剪刀楼梯构件进行使用阶段、施工阶段的静力分析,并对其进行弹塑性分析,揭示其传力机制、变形情况、破坏形态等,所得结论为结构设计提供参考。

The prefabricated beam-type scissor stair component can greatly reduce the weight of the prefabricated steps of the long-span scissor staircase,which has obvious advantages in the current prefabricated building.Taking a project as an example,the finite element software ABAQUS was used to perform static analysis of this type of assembled beam scissors staircase in the use stage and construction stage,and elastoplastic analysis of it to reveal its force transmission mechanism and deformation,destruction form,etc.The conclusions obtained can provide references for structural design.
