Research on Moment Modulation Coefficient of Unbounded Prestressed Concrete Continuous Beam

Abstract:

Through simulation analysis of nonlinear finite element, research ideas on moment modulation coefficient of unbounded prestressed concrete (UPC) continuous beam is proposed ；Based on detailed analysis of the equivalent length of plastic hinge and curvature ductility, the two factors which influencing margin of moment modulation, calculating formulas of curvature ductility coefficient and moment modulation coefficient are established; Compared with the experimental data, the results which provided basic data for further research on plastic design of UPC continuous beam.
