ABSTRACT
High level building is currently often seeing in Gorontalo City. Starting from two-story building untill multistorey. This will make more complicate to design the structure components, especially when the earthquake load given to the structure. To balance the building required sloof planning, because sloof serves as a binder component of the column so that the foundation can work simultaneously.
Building models are analyzed in symmetrical buildings with different levels, which is 4th floor to the 9th floor. Sketch plan size of all building model is identical, which is 25m x 20m ground floor elevation is 4,5m and height between floor is 13m. Structural analysis is using ETABS 2015 and saismic methode used is Spectrum Response Analysis with plan system is using SRPMK.
From the analysis result showed that: the higher a building is, the smaller the ratio of resulting value from sloof considered as beam and sloof as a tie beam. The result of percentage deviation for the 4th floor = 0,17%, 5th floor = 0,09%, 6th floor = 0,07%, 7th floor = 0,04%, 8th floor = 0,03%, 9th floor = 0,01%. While for the percentage value of moment in coloumn for the 4th floor = 74,40%, 5th floor = 59,50%, 6th floor = 54,90%, 7th floor = 37,80%, 8th floor = 27,10%, 9th floor = 19,70%. This happen because the coloumn stiffness ratio becomes dominant.
