Abstract:
In order to acquire the restoring force models on the new prestressed H-steel reinforced concrete composite beams, the simulation analysis was performed on 7 span 3 800 mm and 2 span 4 500 mm prestressed steel reinforced concrete simple beams. The influences of four factors on the monotone moment-curvature curve of section and the monotone load-displacement curve of member were discussed, which were global reinforcing index, prestressing degree, the distance from the centre of prestressing tendon to the bottom of the beams and axial compressive strength of concrete, and the influences of two factors on curvature ductility of section and displacement ductility of member were investigated, which were the global reinforcing index and prestressing degree. The calculation formulas of the curvature ductility and the displacement ductility of prestressed H-steel reinforced concrete composite beams were given by the statistical regression. Finally, the restoring force models for the moment-curvature and the load-displacement of prestressed H-steel reinforced concrete composite beams were established. The results show that prestressed H-steel reinforced concrete composite beams possess good seismic performance, the restoring force models can provide references for elasto-plastic dynamic analysis on structures of this kind of beams.
