PERENCANAAN ULANG GEDUNG FAKULTAS KEDOKTERAN GIGI UNIVERSITAS BRAWIJAYA MALANG MENGGUNAKAN STRUKTUR BAJA DENGAN METODE LRFD

Presently, the use of composite steel materials is rarely applied to high-rise buildings while composite steel has advantages in strength and relatively faster processing time. The advantages gained from using composite steel structures are that the structure becomes more rigid, the service span becomes larger and the stability becomes better.
In the replanning of the Faculty of Dentistry Building, Universitas Brawijaya Malang uses a composite steel structure with the Load and Resistance Factor Design (LRFD) with planning standards SNI 1727:2020 concerning Minimum Loads for Building Planning and Other Structures, SNI 1729:2020 concerning Building Specifications of Structural Steel Buildings, SNI 1726:2019 concerning Procedures for Planning Earthquake Resistance for Building and Non-Building Structures, SNI 7972:2020 concerning Prequalified Connections for Special Moment Frames and Steel Mediums in Seismic Applications, SNI 7860:2020 concerning Seismic Provisions for Structural Steel Buildings, and ANSI/AISC 360-2016 Spesification for Structural Steel Buildings.
The result of size for composite steel produces composite plate thickness t = 120 mm, floor deck type W-1000 base metal thickness 0.70 mm, with wiremesh reinforcement M7.5-100 production from PT. Union Metal WF steel profile on the small beam extends 250x125x6x9 and transverse is WF 350x175x7x11, the core beam is longitudinal transverse is WF 450x200x9x14. For columns, WF profiles are used 400x400x13x21 and Inverted-V bracing uses WF 200x200x8x12. Connection using BSEP (Bolt Stiffened End Plate) connection and for base plate using dimensions of 700x700 mm with a number of anchor of 4 – ø32 mm and a length of 1200 mm.
