RF-CONCRETE 杆件 SLS 验算时的较高配筋需求

附加模块 RF-CONCRETE Members 正在计算满足正常使用极限状态验算所需的非常高的配筋量。 Is there any way to avoid such high values for the required reinforcement?


回复:

如果某根钢筋不能填充到截面或者钢筋层中,那么模块可能会确定用于正常使用极限状态验算的高需求钢筋。 It is also possible that the deflection analysis leads to a high required reinforcement.

One solution might be to increase the maximum number of reinforcement layers. With a higher number of reinforcement layers, it is possible to provide a higher reinforcement (Image 01).

For deflection analyses, it another solution might be to disable the automatic increase of the longitudinal reinforcement for the serviceability limit state design and to define a minimum reinforcement (Image 02). In combination with other SLS checks, it could be useful to calculate the deflection analysis in a separate case.
