PERENCANAAN ULANG STRUKTUR UTAMA GEDUNG FISIP UNIVERSITAS MUHAMMADIYAH SIDOARJO DENGAN PORTAL BETON BERTULANG DAN PELAT LANTAI PRACETAK PRATEGANG HCS (HOLLOW CORE SLAB) BERDASARKAN SNI 2847:2013

Planning a hollow core slab plate structure is taking the case of building projects to study the political science faculty of the social sciences University of Muhammadiyah Sidoarjo. By changing the initial structure that is a conventional plate. In planning the type of hollow core slab plate in terms of the maximum allowable stresses due to the prestressing strand and the load acting on the plate, so that the results obtained do not exceed the maximum and permit control voltage and deflection. This planning through its initial stages of designing a prestressed hollow core slab with a plate thickness planning hollow core slab and prestressed wire calculates the required needs. Planned prestressed slab thickness of 15 cm with Fc '= 40 MPa. It is planned to use 11 pieces of strands, diameter 9 mm Wore pc with fpu = 1570 MPa for a width of 1, 2 m and a diameter of 9 to 5 strand fpu = 1570 MPa to 0.6 m wide. Then calculate the statics portal structure with a combination of loading the dead loads, live loads, earthquake loads according to SNI applicable. Building structure analysis using the StaadPro program shows the results of a large output of a total deviation of 12,613 mm with a drift ratio of 0.0010
