带裂缝工作阶段的短期刚度和挠度分析。
参考来源 - 现浇钢筋混凝土双向板挠度的试验研究Experiment results indicate that PPCCB and the cast-in-situ beam exhibit similar load carrying capability and deformation property. The calculated values of cracking moment,ultimate bending moment,short-term rigidity and average crack interval for PPCCB agree well with testing values.
研究结果表明:从开始加载到破坏,叠合梁与整浇梁表现出相同的受力特点和变形特征;叠合梁的开裂弯矩、极限弯矩计算结果与实测值吻合较好,按整浇梁计算时比真实结果偏于安全;叠合梁的短期刚度及平均裂缝间距实测值与计算结果吻合较好。
