“…These solutions enable the construction of safer and more efficient buildings while minimizing material and energy usage. In structural engineering, irregular structures refer to buildings or other structures that deviate from standard design principles and geometric shapes [1]. The seismic performance of a building depends on many factors, such as lateral strength, stiffness, ductility, regularity, and the degree of simplicity in its configuration [2] [3].…”

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.

“…Vertical irregularities caused by changes in the dynamic properties of structures along their height, e.g., strength, stiffness, and mass, were referred in literature as nongeometric irregularities [24]. A large body of literature is also devoted to the impact of vertical irregularities on the seismic performance of structures [25][26][27][28][29]. Because of the existence of aesthetic consideration and city regulation, irregular configurations, in plan and elevation of buildings, are inevitable.…”

Today, architectural application and economic constraints require that vertical-irregular structures be constructed in urban areas. Proposing methods to minimize damage to these structures during earthquakes is therefore crucial. Strict regulations have been enforced for the design and analysis of irregular structures given their higher vulnerability to damage compared to that of regular structures. The present study aimed to evaluate eight regular and irregular 10-story and 15-story steel structures with buckling-restrained braces frames (BRBFs) and concentric braced frames (CBFs) in terms of their responses to twelve far-field earthquakes. According to the obtained results, the mean value of maximum drift, top floor displacement and floor acceleration were higher in both regular and irregular structures with BRBFs than in those with CBFs.
