肋梁楼盖中次梁的计算方法探讨

Study on Computation of Joists in Girder-Joist Floor System

设计钢筋混凝土肋梁楼盖次梁时，为求得跨中最大弯矩，通常采用折算荷载后按连续梁计算，以考虑实际结构中主梁抗扭刚度的影响。本文对该法的合理性及折算荷载的取值作了探讨。

For the design of reinforced concrete girder-joist floor systems, the maximum mid-span bending moment of joists can usually be found from an assumed continuous beam on which conversed load is applied to take into account the torsional rigidity of girders.The rationality of the method and the conversion factor will be discussed in this paper.
