Despite the attractive merits of high-capacity strands, application in bridge girders is limited due to concerns, including concrete cracking, excessive stress, and cambers. An efficient defect-free production first step wide application. The objective this research was alleviate concerns prestressed using strands. A gigantic box girder 18-mm strands produced; its entire fabrication process (fr...

Abstract Prestressed composite steel-concrete structures are scarcely used due to a lack of clear standardized design guidelines and formulations on the subject. The present research aims methodologies for beams with external pretension applied via straight tendons. A computer program perform structural analysis such was developed based two different methodologies: first one is presented in ABN...

This paper presents the results of a parametric study of the flexural behavior of continuous concrete members prestressed with external tendons. The behavior at ultimate limit states is evaluated. A nonlinear analysis model, based on the three dimensional finite element method, ANSYS computer program (10.0) was used. The nonlinear material and geometrical analysis were adopted. The results obta...
