Abstract

Indonesia is a country located in the path of the Pacific earthquake and the Asian earthquake path that results in a very high risk of earthquakes. Vibrations caused by earthquakes will cause forces on the structure. The design of earthquake-resistant buildings is one of the objectives to prevent structural failure and loss of life. Adding rigidity to a building is a way to overcome resistance to earthquake response. Acquiring stiffness in the structure can be done by combining it with bracing. One type of bracing frame system that can be used is the Concentrically Braced Frame (CBF) system. The analytical method that can be used in this study to account for the effect of earthquake load on the structure is done to analyze the structure's response to lateral load with static analysis and dinamic analysis with comparative analysis of displacement, vibrating period, shear force, and shear lag in buildings. Based on the results of the analysis, the CBF system can reduce the effect of shear lag on the structure. The rigidity of the CBF System is higher than that of the MRF system so that the floor drift and deviation between floors in the system become smaller. The deviation for the x-direction CBF system produces a smaller value of 5% - 32.2%, and for the y-direction it produces 7.2% - 41.7%. In the natural vibrating period of the MRF System structure of 1.311 seconds, this period is worth greater than the period in the CBF System of 0.453 seconds.
