    Penugasan ini akan membahas tentang desain struktural dari Toll Gate Koja yang memiliki dimensi

    sebagai berikut:

      Ukuran: 16,2 m x 12,7 m

      Tinggi: 9,5 m

    Adapun toll gate ini didesain dengan menggunakan material baja yang disusun membentuk truss yang

    menumpu pada girder IWF dan kolom profil H pada kedua ujungnya. Spesifikasi dari material dan

    penampang baja yang digunakan disajikan pada gambar di bawah ini.

    Beban yang diberikan pada pemodelan dengan menggunakan program SAP 2000 meliputi:

    1.  Beban mati (dead Load)

    Beban mati merupakan beban yang berasal dari berat material struktur yang akan dihitung

    secara otomatis oleh program SAP 2000. Adapun berat jenis baja yang digunakan pada

    konstruksi ini adalah 7850 kg/m3.

    2.  Beban superimposed (superimposed dead load)

    Beban superimposed diaplikasikan pada model struktur berdasarkan metode tributary area,

    yaitu untuk purlin sebesar 6,76 kg/m2, roof sheeting sebesar 7 kg/m2, dan ME (Mechanical &

    Electrical) sebesar 20 kg/m2.

    3. 

    Beban hidup (live load)

    Beban hidup yang diaplikasikan meliputi beban hujan sebesar 20 kg/m2 dan beban pekerja

    beserta alat sebesar 100 kg/m2.

    4. 

    Beban gempa (seismic load)

    Beban gempa yang diaplikasikan pada model struktur didasarkan pada kategori risiko struktur

    yang bernilai 2 dan faktor keutamaan gempa yang bernilai 1. Analisis dengan respon spektra

    digunakan untuk menentukan besar percepatan gempa yang akan diberikan pada model

    struktur. Berdasarkan data lokasi pembangunan struktur dan peta gempa Indonesia, maka

    ditentukan beberapa parameter pembentuk respon spektra yang disajikan pada tabel di

    bawah ini.

    Kombinasi pembebanan untuk analisis dan desain struktur baja adalah sebagai berikut:

    a. 

    1.0 (DL + SDL)

    b. 

    1.0 (DL + SDL) + 1.0 LL + 1.0 (Lr or H)

    c. 

    1.0 (DL + SDL) ± 1.0 WL

    d. 

    1.0 (DL + SDL) + 0,75 LL + 0,75 (Lr or H) ± 1 Ex ± 0,3 Eye.

     

    1.0 (DL + SDL) + 0,75 LL + 0,75 (Lr or H) ± 1 Ey ± 0,3 Ex

    Berdasarkan analisis struktur dengan menggunakan bantuan program SAP 2000, diperoleh gaya

    dalam dan deformasi elemen-elemen pada struktur sebagai berikut:

    struktur. Gambar di bawah ini menampilkan gaya dalam maksimum yang terjadi pada elemen-elemen

    model ini.

    Gaya dalam maksimum yang diterima oleh masing-masing elemen struktur diperbandingkan dengan

    kapasitas profil baja dalam menahan tekan, lentur, kombinasi tekan lentur, dan geser. Berikut ini

    Kesimpulan

    Berdasarkan analisis dan perhitungan yang telah dilakukan, diperoleh hasil bahwa elemen kolom dan

    balok H 350x350x9x14 tidak kompak pada pengecekan bagian flange. Solusi yang ditawarkan adalah

    memperbesar penampang, misalnya menggunakan kolom H 350x350x12x19. Pada pengecekan

    elemen double L 60x60x5, diperoleh hasil bahwa kapasitas momen penampang lebih kecil daripada

    beban ultimate yang diterima oleh elemen tersebut. Solusi yang ditawarkan adalah memperbesar

    penampang elemen double L tersebut.
