The building model was made by using ETABS’s software version 9.7.1. Method that was used for earthquake analysis was response spectrum analysis. Result of this research showed that application of two columns dilatation produced different structure behavior when it applied on lengthways direction (X) and breadthways direction (Y) of existing building. Dilatation variation that was given on lengthways direction (X) of building produced better behaviors. More regular building form because of dilatation on lengthways direction (X) produced shorter period with bigger base shear. Along with the base shear that accepted by building, the column momen also became bigger. Based on displacement that was produced, application of dilatation on lengthways direction was influenced by re-entrant corner. Configuration of more regular building that has close re-entrant corner to existing building condition produced displacement that close to the existing, that thing was also in line with story drift that was produced. The displacement that was produced by all dilatation variation was still in safe category according to SNI 03-1726-2012. The biggest displacement that happened on X and Y direction was produced by variation 1 as big as 0.824m and 0.817m in a row.
