A study of tension fields effects on plastic moment of intermediate HBEs in steel plate shear wall

Analytical procedures for estimating the plastic moments of intermediate HBEs under equal an unequal top and bottom tension fields of SPSWs have been developed in this paper. Those proceduresare based on classic plastic analysis and rely on calculation of the reduced axial yield strength of HBEweb accounting for the presence of shear and vertical stresses. For finite element checking, the selected beams in plastic analysis , is modeled in ABAQUS software. Results from plastic analysiswere shown to agree well with the results from finite element analysis. Implementation of thedeveloped analytical procedure is necessary to achieve capacity design of HBE-to-VBE connections, which ensures desirable performance of HBEs like weak beam and strong column theory , that is mentioned in most building codes
