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。
Through a large number of example analysis, the simplified formula of calculating the height of compression zone of B-type component is deduced by regression analysis, which can reduce the workload of stress calculation of cracking section of B type partially prestressed component, especially in deformation calculation After cracking in the section of the moment of inertia calculation workload reduced.
