The use of composite structures is currently less of an option for planning high-rise buildings while the use of composite steel structures will also provide advantages in terms of quality and time efficiency of building work with composite steel structures that are more profitable.
In the Replanning of the FKIP Lecture Building, Sultan Ageng Tirtayasa University Uses Composite Steel with the LFRD Method with planning standards SNI 1727:2020 concerning Minimum Loads for Building Planning and Other Structures, SNI 1729:2020 concerning Building Specifications for 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 Medium Steel in Seismic Applications, and SNI 7860: 2020 concerning Seismic Provisions for Structural Steel Buildings.
From the planning results, the size for composite steel produced a composite plate thickness t = 120 mm, floor deck type W-1000 base metal thickness 0.65 mm, with reinforcement Ø10 mm – 150 mm production from PT. Union Metal WF steel profile on the small Beam Direction Z 250x125x6x9 and Direction X 300x150x6.5x9, The Core Beam Direction Z 450x200x9x14 and Direction X 400x200x8x13. For columns, WF profiles are used 400x400x13x21 and Inverted-V bracing uses WF 200x200x8x12. The connection uses an BSEP (Bolts Stiffened End Plates) type and for the base plate uses dimensions of 700x700 mm with a number of arranges of 4 – Ø32 mm with a length of 1300 mm.
