The Finite Element Analysis on Mechanical Properties of the Meridians Stair Skeleton of Medical Exhibition Center in Taizhou City

The alien space meridians stair steel structure is first adopted in Taizhou medical city exhibition center project. Based on the finite element calculation method for curved beam element stiffness matrix, convergence standard controls and iteration method of solving the modification and optimization in this paper, the complex alien space meridians framed calculation model is built, and the distribution of axial force and bending moment distribution of the stairs meridians skeleton structure are calculated, and the position and numbers are determined. Numerical results show that the maximum space alien meridians stair axial force is 34.5 KN and maximum bending moment is 5.9 KN•m, which satisfy the standard requirement, then the size curvature big, mechanical transmission line complex and local internal force big technology problem skeleton structure have been solved .Therefore, a strong engineering application value achieves in this paper.
