Abstract

The construction of high-rise buildings requires planning that must meet strong security standards so it is necessary to implement a steel Frame tubestructural system with the addition of concentric bracing to prevent collapse due to
earthquake Loads.The steel Frame tube structural system is modeled as a 20-story high-risebuilding, with several variations in the location of concentric bracing such as the
Control Plan Model (MDK), the 4-Side Symmetrical Concentric Bracing Location Model-4 Angle-Center (MLBKSST), the 4-Side Concentric Bracing Location
Model-Without Angle (MLBKSTT), and the 4-Side Concentric Bracing Location Model-4 Angle-2 Center (MLBKSSDT). The earthquake lateral force analysis used response spectrum analysis and the modeling and analysis of the structure was
carried out in 3D with the SAP2000 program.
The analysis results show that the recommended model is MLBKSTT becauset obtained the largest vibration period value with a value of 1.267 seconds, the smallest base earthquake force in the X direction of 3919.873 kN and the Y direction of 3727.299 kN, and the smallest inter-floor deviation in the X direction of 17.706 mm and the Y direction of 19.050 mm
