预应力混凝土连续梁结构塑性设计新模式(下)——预应力混凝土连续梁结构塑性设计建议

New model for plastic design of continuous prestressed concrete beams (Ⅲ)——Recommendations for plastic design of continuous prestressed concrete beams

超静定预应力混凝土结构的塑性设计是一个十分复杂的过程,为方便应用塑性设计新模式进行设计,同时较好地满足正常使用、承载力及防火与耐久性等方面的要求,提出了超静定预应力混凝土结构按经典方法和按统一方法的塑性设计建议,并通过算例展示了按照建议进行设计计算的过程和方法,可供工程技术人员设计时参考。

The process of plastic design of indeterminate prestressed concrete structures is extreme complicated. For applying new model of plastic design conveniently, at the same time, satisfying better service, bearing capacity, fire resistance and endurance, etc, recommendations for plastic design of indeterminate prestressed concrete structures are given, based on traditional design method and unified design method,and an numerical example is used to illustrate calculation process and design method by it for engineering to refer.
