摘要
介绍了北京市新少年宫1号楼异形板柱剪力墙结构中缓粘结预应力筋设计方法;按照空心板的主受力方向并考虑施工方便,确定出空心管的布置方向以及普通筋和预应力筋布置方向;用密肋梁模拟了空心板的受力,并用密肋梁的内力计算结果确定了顺肋方向的配筋;根据结构抗震性特点,在抗震敏感区域采用缓粘结预应力技术来提高结构的抗震性能。
The design method of retard-bonded prestressing bar is introduced in No. 1 building of Beijing Children＇ s New Palace ,which is an irregular slab-column and shear wall structure. The direction of cored pipe as well as reinforcing and prestressing bars are decided based on the primary internal force direction of solid shell and a convenient construction is also taken into account. The internal force of cored slab is simulated with multi-ribbed plate, and the reinforcement along rib is calculated based on the results of multi-ribbed plate. The retard-bonded prestressing technique is applied to the earthquake sensitive area to improve the earthquake resistance ability of the structure.
