RE-ANALYSIS OF BUILDING FOUNDATIONS

Abstract

The carrying capacity of the foundation is the main thing that determines the ability of the foundation to withstand structural loads. A review of the re-analysis of the foundation in this study includes analysis of the allowable bearing capacity of the pile, planning the efficiency and bearing capacity of the group foundation by remodeling the superstructure using the Etabs V 13 program to get the reaction received by the foundation. The regulations used are SNI 03-2847-2002 regarding general regulations on structural planning and SNI 03-1726-2012 regarding earthquake resistance procedures for building buildings. From the results of the re-analysis of the structure, it is obtained that the bearing capacity of the group piles after the addition of the number of floors Q permit = 6298.45 <6549.77 kN (does not meet Q permit pile), P max = 915.75 kN > Supporting capacity of pile pressure permits = 749.816 kN (does not meet), so with these results it can be concluded that the piles used do not meet the priority factor.
