Eight structural models representing 4, 7 and 10-level reinforced concrete frames are dynamically analyzed via Monte Carlo simulation and the Canny-E analysis program. The aim is to establish a simplified procedure to take into account the effects of the accidental torsion in the seismic design of buildings. The results show that it is possible to design a typical office frame building to withstand the accidental-torsion effects by using a simple relationship that amplifies the response of the corresponding torsionally balanced model to estimate the design forces and displacements.

Keywords : accidental torsion; accidental eccentricity; seismic design; seismic torsion; Monte Carlo simulation.
