The Interaction Between Primary And Secondary Structure And Initially Research On Fluid-Solid Effort

Dynamical analysis on primary and secondary structure system is paid more and more attention today. The secondary structure is playing important role on normal working and safety which connected by the primary structure. So much characteristics in this primary and secondary structure system of pre-stress force cable-truss supporting glass curtain wall which decided the vast application in curtain wall structure. Its altitudinal sensibility to wind made the important direction and highlight in structure engineer on researching its wind load carrying.This paper based on FEM and its non-linear characteristic researches the interaction between primary and secondary structure on wind-induced vibration analysis. Firstly, equivalent translation between cable-truss supporting and steel-truss supporting will be implemented. Contrasted the response from the two structures and researched the interaction for the purpose of more economic design scheme. Secondly, it's difficult on either theory or calculating on Fluid-solid effort in large covered structure and worse luck on its aerodynamical damping model. On this condition, a velocity and displacement multiplied are suggested as sorption worked with dynamic wind load which will give a qualitative analysis. All the above provide reference and opinion on structure research and design.ANSYS calculated the structure in time domain by dynamic wind-induced vibration and compared the response of displacement. The analysis and calculation process in this subject are proved valuable according to computer simulation and worked for farther research on cable-truss supporting system in primary and secondary system. Provide reference in studying on wind-induced vibration analysis of large covered structure with the consideration of aerodynamic effort.
