Analysis Method of Secondary Moment in Prestressed Plane Structures

Abstract:

In prestressed plane structures, tensioning prestressing tendons in one direction will bring primary moment in another direction, so the method of calculating secondary moment by removing the primary moment from the resultant moment is not applicable for plane structures, in which the primary moment is calculated by prestressing force multiplying the distance from prestressing force to neutral axis of section. The reason for this method can not be used for calculating secondary moment in plane structures is analyzed. The method for calculating secondary moment in plane structures is presented.
