摘要
基于薄板理论的Navier解和钢筋优化分析,分别建立了保证钢筋混凝土板板底抗裂性能最优和配筋量最少的塑性弯矩比取值优化方法。通过对比,得出了工程中板底弯矩取值的建议公式。板底弯矩比取不同值,可以分别得到抗裂和配筋的优化结果。
The optimized adoption methods of plastic bending moment ratio are derived to make the anti-crack capability best and the mount of steel least separately for reinforced concrete slab bottom based on Navier solution and steel optimization of the thin-slab theory. Through comparison, the suggested formulas are obtained for the adoption of slab moment in reinforced concrete slab bottom in engineering.
