Finite element analysis of rapid footing for industrialised building system

Abstract

The design and innovation of Industrialized Building System (IBS) requires lighter, stronger, better shape, and versatility. Therefore IBS has a common definition and perspective that coordinated in precision to form a structure. This paper presents finite element analysis on two different shape of rapid footing in order to obtain it potential to be immersed using forced vibration. The shapes are different in terms of the bearing area that in contact between footing and the soil surface. Test were conducted on granular soils of elastic modulus of 0.0174 N/mm2and structures are vibrated vertically. The result obtained from the laboratory test on sand is compared with the result from finite element analysis for comparison. The vertical settlement of the footing of model 1 from laboratory test is 2 mm while from analysis is 3.40 mm. The vertical settlement of the footing of model 2 from laboratory test is 7mm while from analysis is at 7.02 mm. Results showed that the footing with confinement wall experienced higher settlement than the footing without wall due to its small contact area.
