GEMPA DENGAN METODE STATIK PUSHOVERRumah sakit merupakan salah satu fasilitas masyarakat yang termasuk
bangunan penting kategori IV sehingga dibutuhkan perencanaan
struktur tahan gempa dimana bangunan harus tetap berdiri setelah
diberikan beban gempa rencana. Analisis pushover merupakan salah
satu metode yang digunakan untuk menganalisis beban gempa guna
mengetahui perilaku keruntuhan bangunan. Penelitian bertujuan untuk
mengetahui dan menganalisis level kinerja struktur, gaya geser dasar
maksimum yang ditahan struktur, pola keruntuhan dan tingkat
daktilitas struktur akibat beban gempa
Berdasarkan hasil analisis, didapatkan nilai target displacement
dengan metode FEMA-356 sebesar 251,6 mm untuk arah-x dan 210,6
mm arah-y sedangkan dengan metode ATC-40 didapatkan nilai
322,027 mm untuk arah-x dan 229,491 mm untuk arah-y. Level
kinerja yang dihasilkan dari kedua metode tersebut adalah damage
control dimana resiko korban jiwa manusia sangat kecil, kerusakan
yang terjadi masih dapat diperbaiki dan bangunan masih mampu
menahan beban gempa rencana yang terjadi. Gaya geser dasar
maksimum adalah 7824 kN dengan displacement maksimum 239,861
mm. Mekanisme keruntuhan struktur menunjukan mekanisme strong
column weak beam. Tingkat daktilitas struktur bangunan berdasarkan
SNI 1726:2002 adalah daktail parsial dengan nilai R aktual 4,07.

The hospital is one of the public facilities that is included in an
important category IV building so that earthquake resistant structure
design is needed where the building must remain standing after being
given the burden of the earthquake design. Pushover analysis is one of
the methods used to analyze earthquake loads in order to determine
the structural collapse behavior of earthquake loads. The purpose of
this study is to determine and analyze the level of structural
performance, the maximum base shear force held by the structure, the
collapse pattern and the level of structural ductility due to earthquake
loads.
Based on the analysis results, the target displacement value obtained
by the FEMA-356 was 251.6 mm for the x-axis and 210.6 mm for the
y-axis while the ATC-40 obtained a value of 322.027 mm for the x- axis and 229.491 mm for the y-axis. The level of performance
produced by the two methods was damage control where the risk of
human casualties was very small, the damage that occurs can still be
repaired and the building is still able to withstand the burden of the
designed earthquake. The maximum basic shear force is 7824 kN with
a maximum displacement of 239.861 mm. The structure collapse
mechanism has strong column weak beam mechanism. The ductility
level of building based on SNI 1726:2002 was a partial ductile with
the actual reduction factor, R was 4.07.
