高效预应力叠合结构在高屋建筑上的应用在保持高层建筑框架柱、主框架梁不变的基础上，将现浇次梁和现浇板改为由预应力叠合梁、叠合板，安装后与面层现浇部分混凝土形成一个整体。这一新结构体系具有下列优点：（１）减少现浇板和次梁的支架、模板的投入。（２）叠合梁、...
The application of high-efficiency pre-stressed superstructure in high-rise buildings In order to keep the high-rise building frame columns and main frame beams unchanged, the cast-in-situ secondary beams and cast-in-place slabs were replaced by prestressed composite beams and laminated plates. After forming a whole with the cast-in-place concrete of the surface layer. This new structural system has the following advantages: (1) Reduced investment in the support and formwork of cast-in-situ slabs and secondary beams. (2) laminated beams,...
