“…The study of Al-Safi et al [15] looked at how seismic and wind loads affected steel structures that were 5, 10, and 15 stories tall and had various bracing systems. To evaluate the base shear, base moment, and story drift for all bracing systems, linear static and nonlinear dynamic studies were carried out.…”

The multi-storey buildings and towers that are constructed of steel frames are exposed to lateral loads such as wind loads, earthquakes and explosions, which cause a vibrational movement in the structure. Therefore, the horizontal drift and deformations increase and lead to instability in the structure. So, it is necessary to retrofit the structural steel buildings by increasing the lateral stiffness and ductility of the structure. This is made by choosing a suitable bracing system type to retrofit the building. In this research, the bracing system types are taken to achieve the desired purpose. A summary of this system and its types, and a historical overview of the use of this system were studied. The results are compared by investigating several parameters, such as the total mass of the structure, the cost, lateral stiffness, and lateral displacement. Also, previous research was categorized following how it affected the reinforcement system. The main objectives of the study are to determine the most efficient bracing system for steel buildings under the influence of retrofitting against a lateral load and to compare the structural performance of various types of bracing systems. Also, the outcomes demonstrated that the bracing system decreases lateral displacement and boosts energy dissipation.

“…The results showed that to reduce both torsional moments and additional rotational displacements, the most appropriate configuration of X‐bracing systems is to locate them in the middle of the triangle sides and continuous. Another study about the linear and nonlinear behavior of steel structures with different bracing systems was documented by Al‐Safi et al [17]. They implemented linear static and nonlinear dynamic analyses to evaluate the base shear, base moment, and interstory drift for several bracing systems in 5‐, 10‐, and 15‐story steel structures, respectively.…”

The main objective of this paper is to study and compare the structural reliability of steel moment resisting frames (SMRFs) and steel frames with X‐bracing systems considering the performance‐based seismic design (PBSD) philosophy. In this sense, to accomplish such a study, nonlinear response history analysis is implemented. The buildings under consideration are designed to be located in Culiacan, Mexico. The results are presented in terms of overall displacements, rotations of connections, and interstory drifts, for three performance levels: (1) immediate occupancy, (2) life safety, and (3) collapse prevention, respectively. For each performance level, 11 ground motions were selected to study the response of the structures. Such responses were extracted by using the SAP2000 commercial software to perform structural analysis. It was demonstrated that the steel frame with X‐bracing systems developed a better seismic performance than SMRFs for all three variables under consideration. In addition, it was found that a reduction up to 70% in overall displacements and interstory drifts can be achieved when X‐bracing systems are used in steel structures. The risk of the structures was extracted in terms of reliability index and probability of failure considering probability density functions of interstory drifts. It was demonstrated that reliability index increased for structures with X‐bracing systems in comparison with SMRFs. Finally, in terms of costs, steel structures with X‐bracing systems are more expensive than SMRFs. However, its use is justified because serviceability conditions as overall displacement and interstory drift are considerably reduced.
