大跨度现浇预应力空心楼板结构设计

摘要

包头市“正翔国际”二期商业IMAX影厅工程，采用了大跨度现浇预应力空心楼板，通过分析结构实际的受力状态，拟定了结构在设计时需要采取的技术措施、设计要求及施工工艺，并对结构计算与构造进行了介绍，对于大跨度预应力空心板设计中可能遇到的问题进行了有益的探索。%The "zhengxiang" international business IMAX screens projectphase iiBaotou used a large span pre-stressed hol ow slab cast.By analyzing the structure of the actual stress state, technical measures and design requirements and construction technology have be taken in the design of the structure.
