Abstract
Gedung 9 Lantai Universitas Muhammadiyah Gresik menggunakan struktur beton bertulang. Desain struktur menggunakan beton dengan metode sistem rangka pemikul momen. Modifikasi desain yang akan dilakukan adalah mengubah struktur yang semula memakai beton bertulang konvensional menjadi struktur baja metode Staggered Truss Framing Systems. STF tidak hanya sebagai penahan gaya aksial tetapi juga sebagai penahan gaya lateral yang diakibatkan oleh beban gempa. Sistem STF efektif untuk bangunan dengan tinggi menengah, seperti hotel, apartemen, rumah sakit, serta struktur lain yang menggunakan tinggi antar lantai yang rendah.
Pada tugas akhir ini perhitungan berdasarkan peraturan SNI 1726:2012 tentang Tata Cara Perencanaan Tahan Gempa Untuk Bangunan Gedung dan Non Gedung, SNI 1729:2015 tentang Spesifikasi untuk Bangunan Gedung Baja Struktural, SNI 1729:2002 tentang Tata Cara Perencanaan Struktur Baja untuk Bangunan Gedung, PPIUG 1983 tentang Peraturan Pembebanan Indonesia Untuk Gedung, dan SNI 1727:2013 tentang Beban Minimum Untuk Perencanaan Bangunan Gedung dan Struktur Lain. Beban gempa dihitung dengan metode beban gempa dinamis respons spectrum, kemudian dianalisis dengan menggunakan program bantu komputer SAP2000.
Dari analisa diperoleh hasil perhitungan, yaitu: tebal pelat atap dan pelat lantai 120 mm, dimensi balok bordes WF 100 x 50 x 5 x 7, dimensi balok utama tangga WF 250 x 125 x 5 x 8 dan dimensi balok penumpu WF 250 x 125 x 5 x 8, dimensi balok penumpu lift WF 300 x 150 x 6,5 x 9. Untuk struktur primer didapat dimensi kolom WF 400 x 400 x 70 x 45; dimensi spandrel beam (Lantai) WF 588 x 300 x 12 x 20; dimensi spandrel beam (Atap) WF 600 x 200 x 17 x 11; dimensi vierendel panel WF 298 x 149 x 8 x 5,5; dimensi truss chord WF 294 x 200 x 12 x 8; dimensi truss diagonal dan vertical HSS 200 x 200 x 12. Serta perencanaan sambungan digunakan baut mutu fub = 8250 MPa. Perencanaan podasi menggunakan tiang pancang beton pracetak berjenis Spun Piles berdiameter Ø40 cm (ketebalan 7,5 cm).

9th Floor Muhammadiyah University Gresik building uses a reinforced concrete structure which called moment frame method. The design modification that will be done is to change the structure which originally uses conventional reinforced concrete into steel structure of Staggered Truss Framing Systems method. STF is not only a barrier of axial force but also as a lateral force holder caused by earthquake loads. The STF system is effective for high-rise buildings, such as hotels, apartments, hospitals, and other structures that use low inter-floor height.
To produce the structural design of steel rational, then this plan refers to the rules that apply include SNI 1726: 2012 on Procedures Planning Earthquake for Building and Non Building, SNI 1729: 2015 on Specifications for Buildings Structural Steel, SNI 1729 : 2002 on Procedures for Steel Structural Design for Buildings, PPIUG 1983 on Indonesian Loading Regulation for Building, and SNI 1727: 2013 on Minimum Load for Planning Building and Other structures. Earthquake load is calculated by the method of dynamic response spectrum earthquake load, and then analyzed using computer aids program SAP2000.
From analysis and the calculation results, the roof plate and floor plate thickness 120 mm, dimensional bordes beam is WF 100 x 50 x 5 x 7, dimensional main strairs beam is WF 250 x 125 x 5 x 8 and dimensional leverage beam is WF 250 x 125 x 5 x 8, dimensional main lift is WF 300 x 150 x 6,5 x 9. While for primer structure obtained the dimensions of the main column WF 400 x 400 x 70 x 45; dimensions spandrel beam (Lantai) WF 588 x 300 x 12 x 20; dimensions spandrel beam (Atap) WF 600 x 200 x 17 x 11; dimensions vierendel panel WF 298 x 149 x 8 x 5,5; dimensi truss chord WF 294 x 200 x 12 x 8; dimensi truss diagonal dan vertical HSS 200 x 200 x 12. As well as planning to use bolt connection quality fub = 8250 MPa. Planning of foundation using precast concrete piles that type is Spun Piles Ø40 cm (thickness 7.5 cm).
