Abstract

In this paper, modified X-braced EBF steel frame is designed using pushover analysis. This study discussed five models of a steel building with 10 floors. The dimension of each model is 18 m width, 18 m length, and 4 m height. The building has a function as an office in Palembang. The building uses two types of EBF bracing, that is X with a vertical link and horizontal link. The result of the study shows that X bracing, with horizontal link model, has the best effectiveness to increase building stiffness and strength. Model 5 with X Bracing and horizontal link can reduce storey drift to 57.71 %, and drift ratio is 72.38%. By pushover analysis, this model gained the most effective performance point with base shear of 441.67 ton. The performance of the five building models is immediate occupancy (IO).
