乌鲁木齐国际儿童医院门诊大厅结构设计

Structural Design of the Entrance Hall of Urumqi International Children's Hospital

乌鲁木齐国际儿童医院由门诊医技楼、病房楼等部分组成,总建筑面积为240000m^(2)。主要介绍了门诊医技楼主体结构设计、入口雨棚设计、大厅屋盖、分叉柱、倒梯形截面设计等多个施工技术问题。通过结构选型对比分析,主体结构采用减震框架结构,雨棚和大厅屋盖均采用单层网壳结构,经济合理的同时保证了建筑效果。通过传力路径分析和有限元计算,对网壳结构进行了单体模型和总装模型的对比研究,重点分析了结构的变形问题,对整体网壳进行了几何非线性和材料非线性的整体稳定性分析,对倒梯形截面采用截面替换的方式进行了补充分析,对支座等关键部位进行有限元分析以满足受力和稳定性的要求。

Urumqi International Children's Hospital is composed of outpatient medical technology building and ward building,with a total construction area of 240000 m^(2).This paper introduces the main structure design of outpatient medical technology building,entrance canopy design,hall roof,bifurcation column,inverted trapezoidal cross-section design and other technical problems.Through the comparative analysis of structure selection,the main structure adopts the damping frame structure,the canopy adopts the single-layer reticulated shell structure,and the hall roof adopts the beam string structure,which is economical and reasonable,and ensures the architectural outlook.Through the force transfer path analysis and finite element calculation,the comparative study of individual and final assembly model is carried out for the reticulated shell structure,focusing on the deformation of the structure,the overall stability analysis of geometric nonlinearity and material nonlinearity is carried out for the whole reticulated shell,the inverted trapezoidal cross-section is supplemented with cross-section replacement,and finite element analysis is carried out for the key sections such as the support to satisfy the requirements of force and stability..
