Analisis Pengaruh Beban Gempa pada Gedung Tiga Lantai Menggunakan Metode Statik Ekuivalen

Abstract

The purpose of this study is to evaluate the effect of earthquake load on the structure of a third floor school building in West Lampung. The effects of earthquake is reviewed on the dimensions, reinforcement, and deflection of structures by comparing building without earthquake load.

The earthquake load calculation using Static Equivalent Method is helped by SAP 2000 program. This program can also produce internal force of the moment, latitude, and normal (M, D, N). The calculation of the slab is calculated by direct design method (DDM).

The results of this analysis showed that the calculation of all reinforcement requirements on slab, beams, columns, bore pile foundations, sloof and pile caps in the building with earthquake load 283,3267% is more than compared to the building without earthquake load seen from the number of as on each structure. Dimension design on the structure without earthquake load result that dimension of beams are 250 x 450 mm, coloumns are 350 x 350 mm, diameter of bore piles are 70 cm, sloofs are 250 x 450 mm and pile caps are 1600 mm while the dimensions of the structure with the earthquake load resulted in larger dimensions with dimension of columns are 600 x 600 mm, diameter of bore pile foundations are 80 cm, and pile caps are 1800 mm.

Keywords: earthquake load, static ekuivalen, direct design method, and SAP2000.
