研究了不同预应力施工顺序和建造方法的Ⅱ类截面预应力钢－混凝土组合梁受弯承载力的弹性分析和弹塑性分析方法，给出了计算弹性和塑性极限荷载的基本方程．计算结果和试验结果较为吻合，可供设计与施工参考．
The elastic analysis and elasto-plastic analysis method of flexural capacity of prestressed concrete-filled steel reinforced concrete with Ⅱ section under different prestressed construction sequence and construction method were studied. The basic equations for calculating the ultimate load of elasticity and plasticity were given. Calculation results and test results are more consistent, for design and construction reference.
