Abstract

Introduction to the seismic parameter for structural analysis has increased the awareness of better quality for a building to reach safety purpose limit. Considerably, the configuration and shape of the building must be restricted to the regular one. This paper will harness horizontally irregular building to be remodeled into several regular buildings. Furthermore, linear dynamic analysis by using response spectra is harnessed for gaining behaviour of the buildings and capacity of structural members. Beams are chosen to be discontinuous at several corners to create separation on the building; hereinafter, console beam system is implemented. Next, the double column is utilized to obtain the separation of the horizontally irregular building. Entirely, the discontinuity issue of applying dilatation leads to the behaviour of the building and capacity of the structural member inside. Further discontinuity distance which is shown in a double column system can be settled down by applying dilatation in the accurate building axis so that the failure will not be severe or simply deducting the gap between twin columns. In contrary, console beam satisfactorily behaves in order to decrease horizontal irregularity even turn it into the regular building. Moreover, the capacity of the building can be significantly enhanced as the shear wall is installed.
