Study on Seismic Reinforcement Measures and Schemes of Irregular Frame Structures FENG Zi-yu, YANG De-jian, WANG Xiao-nan 2019, 29(1): 1-9.  DOI: 10.16046/j.cnki.issn2096-5680.2019.01.001 Abstract ( )   PDF (3079KB) ( )   In this paper,the SAP2000finite element analysis software was applied to model the original frame of an existing irregular plane framework in Tianjin and the elastic-plastic time-history was analyzed.The BRB damping and anti-torsional reinforcement scheme was proposed based on the analysis results and the characteristics of the project.Compared with the original frame,the period ratio of BRB frame was reduced by 26%,torsional displacement ratio was decreased by 15%;decreasing of inter-story displacement angle could reach 31%and the maximum displacement angle of the top layer could be controlled within the scope of the code.The results indicate that BRB not only increases the anti-lateral stiffness of the structure,but also improves the seismic performance of the structure,which is an effective approach to control torsional effect of irregular structures.
