Daftar Isi:
- Storey building or high-level structure requires planning that includes analysis of concrete strength, strength analysis of structural elements, and dynamic analysis for seismic loads. Seismic or earthquake loads need to be considered into account because of the damage caused is quite severe, especially in earthquakeprone areas such as Indonesia. Seismic force is usually work as a horizontal load on the ground surface, so that the design of earthquake-resistant buildings need to add structural elements resisting the lateral force. This research was conducted to compare the dynamic behaviors that work on the overall structure and column element forces that occur between resisting lateral structural system with shear walls and structural system with steel bracing. The structure is designed as partially moment resisting frames. Modeling of structural systems is designed by using SAP2000 program. Modeling of seismic forces using the latest regulation, SNI 1726:2012, where earthquake risk- targeted plan (MCER - Targeted Maximum Considered Earthquake Risk) defined as the maximum possible earthquake magnitude is exceeded during the lifetime of the structure is 50 years at 2% or earthquake with a return period of 2500 years. The results of the analysis and design of structural systems, show that the steel bracing system with WF profile 300.150.6,5.9 (T = 0.671 sec), providing higher rigidity/stiffness than the existing system of shear wall structure with fc' = 30 MPa (T = 1.18 sec). At the moment at the ends of columns and shear forces due to earthquake loading, steel bracing system generates smaller force than the strutural system with shear wall. Torsional moment working on the column due to the configuration of the placement of lateral resisting shear wall generates force which is quite high compared with the torsional moment generated by the placement of steel bracing.
