In Structural design safety and economical aspect are very important, therefore some building
codes i.e, “Tata Cara Perhitungan Struktur Beton untuk Gedung” SNI 03–2847–2002 and “Tata
Cara Perencanaan Ketahanan Gempa untuk Bangunan Gedung” SNI 03–1726–2002 will be used as
references in structural design.
Building which has been designed is 18 stories building where it is located in earthquake
zone 3, therefore full ductility as ductility level and Special Moment Resisting Frame system are
considered in design. Structural analysis by using ETABS v 9.07. and according to codes as
mentioned at above, which the structure itself is modeled as 3 dimensional building.
From structural design result, the entire slab has the thickness 120 mm most of them are
designed as two-way slab and some designed as one-way slab with reinforcement bar 10 mm. Stair
has the thickness 150 mm, with reinforcement bar 10 mm. Dimension of beam B298 at story 14 is
350x600, longitudinal reinforcement for support area are 6D20 (top reinforcement), 4D20 (bottom
reinforcement), longitudinal reinforcement for midspan area are 4D20 (top reinforcement), 4D20
(bottom reinforcement). Dimension of column C38 at story 14 is 600x600 mm, longitudinal
reinforcement has 20D20, and transversal reinforcement has P10 – 100.
