PERENCANAAN STRUKTUR ATAS HANGGAR DI BANDAR UDARA KALIMARAU KALIMANTAN TIMUR

Perencanaan struktur atas hanggar pesawat di Bandar Udara Kalimarau,
Kalimantan Timur, dilakukan untuk mendukung pengembangan fasilitas
transportasi udara. Hanggar dirancang berukuran 76 m × 75 m × 13 m, dan mampu
menampung pesawat Boeing 737-800 serta ATR 72-500. Selain untuk operasional
internal, hanggar ini juga direncanakan untuk dikomersialkan melalui penyewaan
kepada operator lain, sehingga desainnya harus memenuhi aspek kekuatan,
efisiensi, dan keselamatan.
Struktur atas menggunakan sistem rangka atap tipe truss baja, yang efisien
untuk bentang besar. Analisis dilakukan dengan software SAP2000, mengacu pada
SNI 1727:2020, SNI 1726:2019, dan SNI 1729:2020. Beban yang dianalisis
meliputi beban mati, hidup, angin, dan gempa.
Elemen utama terdiri dari kolom WF 588 × 300 × 12 × 20, batang truss
frame dari pipa baja diameter 10 dan 8 inci, serta bracing dan penyokong dari profil
L dan pipa. Hasil analisis menunjukkan beban maksimum terjadi pada kombinasi
angin dan gempa. Beberapa penyokong perlu peningkatan penampang akibat
tegangan berlebih.
Setelah dilakukan kontrol penampang terhadap gaya aksial, momen, geser,
dan kelangsingan, seluruh elemen struktur dinyatakan aman dan layak. Hasil ini
menunjukkan bahwa struktur baja dapat digunakan secara optimal untuk
pembangunan hanggar skala besar yang bersifat komersial dan fungsional.

===============================================================

The structural design of the upper structure of an aircraft hangar at
Kalimarau Airport, East Kalimantan, was conducted to support the development of
air transportation facilities in the region. The hangar is designed with dimensions
of 76 m × 75 m × 13 m and is capable of accommodating Boeing 737-800 and ATR
72-500 aircraft. In addition to internal operations, the hangar is also intended to
be commercialized through leasing to other operators; therefore, the design must
fulfill aspects of strength, efficiency, and safety.
The upper structure uses a steel roof truss system, which is efficient for longspan
buildings. The structural analysis was conducted using SAP2000 software,
referring to national standards: SNI 1727:2020, SNI 1726:2019, and SNI
1729:2020. The applied loads include dead loads, live loads, wind loads, and
seismic loads.
The main structural elements consist of WF 588 × 300 × 12 × 20 columns,
truss frame members made of 10-inch and 8-inch steel pipes, and bracing and
support elements using L profiles and pipes. The analysis results show that the
maximum load occurs under a combination of wind and seismic loads. Some
support elements required section upgrades due to overstress.
After performing section checks for axial forces, bending moments, shear
forces, and slenderness, all structural elements were declared safe and feasible.
This study confirms that steel structures are optimally suitable for the construction
of large-scale, functional, and commercially oriented aircraft hangars.
