Application of ANSYS in Grid Structure

摘要

Space grid structure of modern large span structure engineering in the most commonly used structure form.This paper used ANSYS network space truss finite element analysis,discuss the element type,and the selection of material models,and the definition of the limit stress,when necessary,even considering the bar buckling state (buckling).Under various load (permanent loads,wind loads,seismic loads,under the action of gravity),using the powerful finite element analysis software ANSYS on the structure static analysis,after the use of ANSYS powerful optimization design function,the structure safety,the bar section optimization design,and then on the basis of the existing rod a cross section,a reasonable choice of bar section,reduce the material consumption,to achieve the best economic,reasonable design,implementation can develop continuously,make the satisfactory design.
