现浇预应力空心板的工程应用

结合某公共建筑中会议厅20.9 m×36 m大开间的工程特点,对单向现浇空心板的截面选择、内力计算、预应力筋及非预应力筋的确定和结构的整体设计进行了详细分析,并提出存在的问题及设计要点,可为类似工程设计提供指导。

On engineering application of cast-in-place prestressed hollow plate

Combining with the engineering features of 20.9 m×36 m large room at a meeting hall of some public building,the study has the detailed analysis the identification of the section selection,the internal stress calculation,the prestressing tendon,and the non-prestressing tendon for the single-direction cast-in-place hollow plate and the structural integrated design,and points out some problems and design points,so as to provide direction for the design of similar projects.
