部分预应力B类构件受压区高度简化计算
Simplified Formulas of Height of Compressive Region of Partially Prestressed B Type Member
【摘要】 通过大量的算例分析,用回归分析的方法得出B类构件受压区高度计算的简化公式,可以使部分预应力B类构件开裂截面的应力计算工作量有所减少,特别是在变形计算中开裂后截面惯矩的计算工作量有所减少。
【Abstract】 On the basis of analyzing a lot of calculating examples,the simplified formulas of calculating the height of compressive region of partially prestressed B type members are got by regression analysis.The workload of stress calculation of cracked section of partially presstressed B type members is reduced and the workload of moment of inertia calculation of cracked section in deformation calculation is specially reduced.
