Analysis and Application of Stability Bearing Capacity of Fastener-style Suspended Tubular Steel Formwork
Based on the engineering background of a fastener-style suspended tubular steel formwork for the Ba-tang Toru Hydropower Project in Indonesia,theoretical study and numerical analysis were conducted on the fastener-style suspended tubular steel formwork.The finite element analysis software MIDAS/Gen was used for modeling,the linear buckling analysis of the structure was carried out by using the semi-rigid connection of right-angle fastener to evaluate the stability capacity of the structure,and the nonlinear buckling analysis was carried out by introducing geometric initial defects.On this basis,the influence of the right-angle fasteners of the structure under different torsional moments and different arrangements of diagonal braces on the stable bearing capacity of the structure was studied,providing a certain reference for subsequent research.
