【摘要】 提出一种新型的叠合梁结构———U形预应力预制构件叠合梁,探讨了其结构特点。通过二根叠合梁及一根整浇梁的对比试验,研究分析了此种叠合梁的受力特点、破坏特征和受弯承载力,并提出正截面受弯承载力的设计建议,以促进其在我国的推广应用。更多还原

【Abstract】 A new kind of composite beams,composite beams with U-shaped prestressed precast elements,was presented and its structural characters were discussed.By experimenting upon two composite beams and one integral casting beam,their bending characteristics,failure properties and bearing capacity were studied and analyzed.Then the design suggestions were put forward,to promote their application in china.更多还原
