| Abstract Nonlinear numerical analysis of the structural behaviour of prestressed steel reinforced concrete (PSRC) beams was carried out by using finite element analysis software ABAQUS. By comparing the load-deformation curves, the rationality and reliability of the finite element model have been confirmed; moreover, the changes of the beam stiffness and stress in the forcing process and the ultimate bearing capacity of the beam were analyzed. Based on the model, the effect of prestressed force, and H-steel to the stiffness, the ultimate bearing capacity and ductility of beam were also analyzed. 1. IntroductionNowadays, the prestressed concrete structural components with their excellent performance have a wide range of applications in housing construction, bridges, water, and other civil engineering projects [1–5]. Prestressed steel reinforced concrete (PSRC) structure is a new type of structure which improves the mechanical properties with the application of the prestressed technology. PSRC structure has double advantages of steel reinforced concrete (SRC) structure and prestressed concrete structure; the built-in steel can improve the structural load carrying capacity and seismic performance, while the application of prestressed technology can ameliorate the performance of the structure under service load conditions (such as crack control and deformation control), so PSRC structure is easy to achieve large span, heavy load structure [2, 6, 7]. |
