METHOD FOR DETERMINING AN OPTIMAL ARRANGEMENT OF CIRCULAR PIPE SUPPORTS OF STEEL SILO COMPOSITE SHEAR WALL

摘要

A method for determining an optimal arrangement of circular pipe supports of a steel silo composite shear wall, including: designing a set of steel silo composite shear wall model including parameters of interval of the circular pipe supports, axial-load ratio, steel ratio and aspect ratio: establishing an ABAQUS finite element model including initial defect; performing force analysis by the finite element software ABAQUS and calculating a horizontal ultimate bearing capacity; fitting formulas of the horizontal ultimate bearing capacity of the steel silo composite shear wall by applying least square method; drawing a relationship curve between the interval of the circular pipe supports and the horizontal ultimate bearing capacity; determining the optimal arrangement of the circular pipe supports of the steel silo composite shear wall according to a critical point of the relationship curve between the interval of the circular pipe supports and the horizontal ultimate bearing capacity.
