Does midas Civil considers the weight of the rebar of an composite-section.
As such, the weight of reinforcement isn't considered in self-weight. However, if the option as shown in the image below is activated, then the self-weight of re-bars is considered separately. Again, the load is just for longitudinal bar and not for shear bars in case of other types of section. As such, the contribution of this weight to over-all effect is quite low. If required, the density of concrete could be modified to adjust for this increase in reaction, though, I personally won't recommend it.
