Numerical Modeling of Structural Irregularities on Unsymmetrical Buildings

Since the formation of the world, it is known that the earthquakes in seismic-active regions are occurring in sequences and from their results there are losses to millions of people and buildings. As Turkey is located in one of the worldꞌs most active seismic zones there are many studies for minimizing the damages especially at buildings during earthquakes. In this study, the seismic analyses were handled for a 10-storey unsymmetrical (L-shaped) building according to the Turkish Earthquake Code (TEC). These analyses contain the controls of A1-torsional irregularity, B2-weak-storey irregularity, relative storey displacements and second order effects. Furthermore, due to the lack of symmetry of the building, model was analysed for both +X and +Y directions. In order to correct irregularities which would occur in building models, the shear walls will be placed in different +X and +Y axles and positions and the analyses were repeated. According to the results for the case of an earthquake the safest and the most economical building model was suggested. Loads in all analyses in the study were calculated using "Equivalent Earthquake Loading Method" stated in TEC. The results will reveal a new look especially in the earthquake engineering
