The purpose of this study is to apply H-steel beam to the prestressing theory and to investigate the effect of structural behavior by the prestressed force and the curved shape of PC strand wire.
In addition, test results, theoretically analyzed solution by load balancing concept and finite element results by the program of ANSYS are compared, and an interactive behavior to the test specimens subjected to combined loads is compared with prestressed theory and finite element analysis. Six different types of beam specimens contained a standard specimen are composed two types by the variables of prestressed force and four types by the variables of curved shape of PC strand wire. The non-linear finite element analysis considering geometrical and material has been used to predict the behavior of prestressed beams.
