PERENCANAAN ULANG STRUKTUR UTAMA GEDUNG PASAR LEGI KABUPATEN PONOROGO MENGGUNAKAN STRUKTUR BAJA KOMPOSIT DENGAN METODE LRFD

Re-design of the Main Structure of the Legi Market Building in Ponorogo Regency Using Composite Steel Structure with the LRFD Method and using SRPMK planning. Composite steel was chosen because of its ability to withstand high loads with lighter weight and ease of construction. In this final project, several planning standards were applied, including SNI 1729-2020, SNI 1726-2019, and SNI 2847-2019. The planning results show the use of 120 mm thick composite plates with 0.70 mm floordeck and M7.5-100 mm wiremesh. For beams, WF 250×125×6×9 profiles are used for child beams and WF 450×200×9×14 for main beams, with M19 type shear studs to withstand shear forces. The planned columns are composite columns with KC 600×200×11×17 profiles and 8 D20 main reinforcements. The connection used is Bolt Stiffned End Plate 8ES (BSEP 8ES).
