Structural Design of the Entrance Hall of Urumqi International Children's Hospital
Urumqi International Children's Hospital is composed of outpatient medical technology building and ward building,with a total construction area of 240 000 m2.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..
