摘要
通过对预应力混凝土叠合连续梁、混凝土叠合框架梁、预应力混凝土叠合框架梁及相应的对比梁、对比框架梁在竖向单调荷载下的试验成果分析 ,证实了二阶段制造、二次受力不会降低叠合受弯构件的延性 。
This paper is based on the experimental results of R.C. composite continuous beams, R.C. composite frame beams, prestressed R.C. composite continuous frame beams and their contrast elements being under the monotonous closing vertical load. It is verified that two-stage loading and two -stage manufacture will not reduce the ductility of composite bending elements. In the paper it is also given the designing method and structural measure to ensure the ductility of composite elements.
