The key designation on steel skeleton structure of channel curtain wall of medical city exhibition Center of TaiZhou City in China

Taizhou medical city exhibition Center project first adopts channel curtain wall structure, with a beautiful shape, tilt angle and high technology, which solves the key technical design problems of uneven distribution of internal forces in steel skeleton system and large local deformation. On the premise of the comprehensive analysis of several different load combination, irregular geometric space model including the 6345 nodes are established. Through the modification of thin-walled curved beam element stiffness matrix, optimization of iterative process and the definition of convergence criteria etc, these key values of innovation are used to realize the dual nonlinear and obtain the diagram of axial force and diagram of displacement by numerical calculation under the most adverse conditions of load combination, and the numerical results meet the specifications demand of structural design. Based on it, the design of construction drawing is creatively completed so that the project achieves a good comprehensive efficiency.
