PERENCANAAN GEDUNG FUTURUM SUITE DENGAN SISTEM RANGKA PEMIKUL MOMEN KHUSUS (STUDI KASUS PADA GEDUNG KBGI-XIII :FUTURUM SUITE)

Malang city is one of the cities in East Java province which is nicknamed the student
city. As a metropolitan city, the need for primary housing is very necessary, with
vertical housing it will maximize land use. The Futurum suite building is an 8-storey
building in the precast concrete category in the 2022 KBGI championship and won
3rd place with a vibrating table testing frequency of 1.5 Hz - 5.5 Hz. Apart from
that, it also won sustainable material innovation by adding carbon fiber to the
concrete mix. This building uses an earthquake resisting system in the form of a
special moment resisting frame (SPRMK) because it was planned for a tall building
with earthquake analysis using the equivalent static method. Planning will refer to
SNI 2847-2019 concerning structural concrete requirements for buildings and SNI
1726-2019 concerning procedures for earthquake resistance planning for building
and non-building structures. The building was re-planned with dimensions of 1:50
using beams measuring 35/45 cm, and columns measuring 60/70 cm, floor plates
150 mm thick, roof plates 120 mm thick and a building height of 28 m. Based on
this plan, the largest plastic deviation between floors is 16.34 mm, which is smaller
than the permit deviation of 70 mm. From the analysis results it can be seen that
the value of θ ≤ 0.10. So in structural analysis, the influence of P-Δ is not taken into
account.
