新型预应力混凝土结构的设计研究

The Design Research of New Type of Pre-Stressed Concrete Structures

文章提出了将高强钢构件所建立的预压预应力杆件,置于钢筋混凝土受弯构件受压区的新型预应力混凝土结构。从设计理论角度,深入研究了该新型结构的承载能力和应力变化,进而在设计实践、设计对比中,进一步证实了新型预应力混凝土结构较一般预应力混凝土结构更具建筑的优越性和经济性。

The paper focuses on the issue of using high-strength steel member which is pre-stressed and the compressed member is embedded in the compression area of flexural reinforced concrete structure. Based on design theory, detailed analysis of loading capacity and stress variation,it is proved that the new structure achieves advantage of economy by comparing with conventional pre-stressed structure in respect of practical design methods.
