Perencanaan Struktur Atas Dan Bawah Gedung Kantor Pu Di Timor-Leste

Abstract

East Timor is a small country located to the northwest of Australia and shares
the mainland with the province of NTT, Indonesia. Along with the various
developments of the world, developments in the field of civil engineering have also
been carried out, including infrastructure, bridges and high-rise buildings. All these
buildings can only be sturdy with a strong building structure to withstand the forces.
In planning the superstructure, the calculations were made using the etabs 9.7.2
program with the concrete material. The results of the superstructure obtained are:
2 types of columns with the following dimensions: 750x550mm & dia. 650mm; 5
beams with these dimensions: 600x350mm, 550x300mm, 400x250mm,
500x300mm & 300x200mm; 2 slabs with these respective dimensions: 125mm &
150mm; and 1 shear wall with the dimension of 250mm. The ratio of concrete
obtained to the building area is of 0,26. For the substructure planning, it was used
3 methods (O'Neill & Reese (1989), Meyerhof (1976) and Reese & Wright (1977))
for a compressive bearing capacity as deep as 16m with a foundation type bored
pile with a diameter of 80cm, to obtain a permit bearing capacity amounting to 92
tons for gravity, 119 tons for moderate earthquake forces and 143 tons for strong
earthquake forces. The number of foundation points was 394 with 12 types of pile
caps (PC-2, PC-3, PC-4, PC-5, PC-6, PC-7, PC-8, PC-9, PC-10, PC -15, PC-20 &
PC-40). For the settlement calculations for single piles, the Poulus & Davis (1980)
method was used and for the settlement of pile groups in granular soil conditions,
it was used the method of Skempton et al. (1953), from which the maximum
settlement result was 40mm.
