Title: MULTI-SCALE FINITE ELEMENT ANALYSIS OF STEEL TUBE TOWER FOR LARGE CROSSING TRANSMISSION LINES
Abstract: Multi-scale calculation can obtain an appropriate balance between computational precision and computational cost,and it has been widely applied in many subjects and engineering purposes.To accomplish a reliable interface between a global model and a local model,a multi-point constraint equation method is realized in finite element software based on the multi-scale calculation theory,and applied in the study of the mechanical properties for a steel tower.The multi-scale finite steel tower simulation result is verified by a TTA model,a rigid-framed model,a truss-framed model and an experiment.The results show that the multi-scale finite calculation can efficiently simulate the whole steel tower mechanical behavior and the complex bonding stress distribution between different connection parts.The proposed methodology is applicable in civil engineering.
