In this paper, the main objective is to develop incremental dynamic analysis (IDA) curve of the regular and irregular shape of the building based on concrete material and ground motions. The regular shape was rectangle shape whereas irregular shape is L-shape. 7 sets of ground motions were used in this research for regular and irregular shape of the building. The structural components of the building were designed based on Eurocode 2 with the aid Eurocode 8 for earthquake loading. Wind load was applied to the building in x-direction and y-direction based on MS 1553. The SAP2000 was used as the main tool to carry out the analysis. The nonlinear dynamic analysis also called incremental dynamic analysis (IDA) was carried out with 7 sets of ground motion records that fulfil the criteria such as the distance of earthquake event to the station is less than 15 km, the earthquake magnitude is equal to or greater than 5.5 M and the PGA is equal to or greater than 0.15 g. 7 sets of ground motion were converted to response spectrum and scaled according to soil type A to develop the elastic response spectrum. The drift limit of the building was determined. The inter-storey drift of regular and irregular building were determined to predict the damage of the building. Form the IDA results, it was proven that regular building performs better as compared to an irregular building.
