EARTHQUAKE RISK AMPLIFICATION BASED ON ARCHITECTURAL PLAN IRREGULARITY

The collapse and heavy damage reasons of buildings has been investigated in terms of quality of materials and workmanship after a severe ground excitation. However, there is an unforeseen reason except for production phase of the buildings. This is the architectural plan irregularity of buildings which cannot satisfy demand spectra. In this paper, this unforeseen problem is investigated with a case study of a residential building which is planned to be constructed in a state university of Turkey. For this purpose, nonlinear static analysis procedure was performed on a selected plan for sake of performance of selected building as a proactive decision before construction phase to eliminate human and property loss. This proactive analysis method gives an insight into engineers to track performance of the building before starting construction. Absence of beam, free span-length of beams and shear walls were considered in this study as a misusing structural element. Practical contribution of this paper provides designers to perform nonlinear static analysis after linear static procedure to satisfy demand of the building according to seismic zone of the construction territory to eliminate architectural plan irregularity.
