| Abstract |
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, theoretically analyzed solution by load balancing concept, finite element results by the program of ANSYS package program and the results by beam test are compared. And structural behavior of the specimens subjected to combined loads is compared with prestressed theory and finite element analysis.
Six different types of beam specimens are composed of a type of the standard specimen and two types with the variables of prestressed force and four types with the variables of curved shape of PC strand wire. The non-linear finite element analysis considering geometry and material has been used to predict the behavior of prestressed beams. |
