Research on prestressed loading strut of cable supported portal frame

Abstract In this study, a novel type of loading strut device is presented, which introduced in portal frame external prestressing reinforcement and used to constitute cable-supported structural system. The was found be capable elongating by rotating the middle screw applying prestress steel strand new simulated analyzed using ANSYS finite element analysis software. Moreover, it for test practical project. During test, load applied through strut, changes strain, mid span deflection at key positions before after are investigated. Based on simulation results, that simple, safe reliable operate, could employed structure system without tensioning achieve loading.
