The usual practice for the calculation of deflections in reinforced concrete frames consists of a linear-elastic analysis of efforts and a calculation of deflections from these efforts, taking into account the cracking of the concrete. The method is not congruent and may leads to important differences in the computed deflections. When a non-linear analysis is made for computing the efforts to calculate the deflections, the instantaneous deflections are not affected by redistribution between top and bottom reinforcements. In this paper a simplified method for reinforced concrete frames computing in service is presented, including cracking effects.
