Abstract:

An irregular structure refers to buildings or other structures that deviate from standard design principles and geometric shapes. Based on previous studies, one of the factors that causes failure of an irregular structure is the asymmetrical shape, which causes uneven load distribution in the structure. Therefore, this study aims to evaluate an irregular-structure building and bracing type X on this structure. The evaluated parameters were the period, modal participating mass ratio, base shear, story drift, and DCR. The modelling process was performed using ETABS, an element-based structural modelling software. The results indicate that failure occurred in the structure under the existing conditions in terms of the modal participating mass ratio, story drift, and DCR. The model with bracing type X indicates a reduction in the period and rotation Z (RZ) of the participating mass. The story drift on the model with bracing type X also indicates a significant reduction; however, in model 1,3, and 5, the story drift value did not meet the story drift requirement. The DCR values of the column and beam in the model with bracing type X also indicate a reduction; however, there are some elements in the structure that do not meet the requirements of model 1,3, and 5. Bracing placement at the corner of the structure has a more significant effect on the structure.
