摘要
为减少工程造价并确保地下车库的安全使用,提出了通过永久荷载与常遇活荷载组合下的裂缝与变形控制方程确定预应力筋用量,依据永久荷载与罕遇活荷载组合下的内力设计值及有关构造要求确定非预应力纵筋用量的思路和方法。方案对比表明,按本思路和方法进行设计经济效益显著。
In order to reduce construction cost and meet the garage safety and serviceability requirements, the prestressing tendons are determined by crack and deform control equations in combination with permanent load and frequent load. Nonprestressing steel bars are determined by relative construction requirement and designed inner force in combination with permanent load and infrequent load. Comparison shows that the design made with this method is economic distinctly.
