Abstract
In an effort to reduce the loss of life and damages caused by the earthquake, the Ministry of Public Works has released the latest Indonesia Earthquake Hazard Maps in 2010. This map illustrates the peak acceleration and response spectra at bedrock probabilistic analysis for the various periods of the earthquake. With the issuance of the 2010 Indonesian Earthquake Map has a different concept to the Indonesia Earthquake Maps contained in SNI 03-1726-2002, it is currently being drafted RSNI3 03-1726-201X refers to ASCE 7 in 2010.
Dang Merdu Tower of Bank Riau Kepri is one of the new irregular buildings built in the city of Pekanbaru that calculations still refer to SNI 03-1726-2002. For that conducted research on the differences in the performance of the structure when earthquake loads imposed SNI 03-1726-2002 and RSNI3 03-1726-201X.The results showed that the seismic force-resisting system that may be used by SNI 03-1726-2002 is dual system Intermediate Moment Resisting Frame with reinforced concrete shear wall. While the structure of the system that may be used by RSNI3 03-1726-201X is a dual system Special Momen Resisting Frame with special reinforced concrete shear wall.
Under each of these systems base shear force result of earthquake loads of RSNI3 03-1726-201X increased by 27.85% compared to SNI 03-1726-2002. Total drift by the earthquake load of RSNI3 03-1726-201X increased by 34.94% in the X direction and 32.85% in the Y direction of the total drift of SNI 03-1726-2002. Overall structure can resist load combination of SNI 03-1726-2002 however, the structure could not resist load combination of RSNI3 03-1726-201X it looks a structural component experiencing overstress.
