PERENCANAAN STRUKTUR GEDUNG KULIAH SEKOLAH TINGGI TEKNOLOGI RONGGOLAWE CEPU DENGAN ANALISA STRUKTUR MENGGUNAKAN SOFTWARE ETABS VERSI 20

Abstract

Structural planning of conference buildings at Ronggolawe High School of Technology Cepu using structural analysis using ETABS version 20 software includes planning of upper and sub structures, planning using ETABS version 20 program. floors as superstructure elements, and cantilevers and piles as substructure elements. The quality of the concrete used is fc' 25 MPA and fc' 30 MPA. Steel grades for the roof structure have a yield strength (fy) of 240 MPA and a ultimate strength (fu) of 370 MPA. 240 MPA grade steel for reinforcement with a diameter less than or equal to 12 mm, and 400 MPA grade steel for reinforcement with a diameter greater than 12 mm. The loads reviewed for the planning of these structural elements are dead loads, live loads and seismic loads. The structure was designed using the ETABS version 20 application. The structural planning results obtained in this final project are the dimensions of the roof, columns, beams, slabs, screed and pile.

Based on the calculation of the roof structure using channel hooks 150.130.20.3.2 and the structure of steel rods with isosceles profiles 75.75.10, 60.60.10 and 60.60.6. The connection uses 2 rivets on each knot plate. For plate reinforcement using main reinforcement D10 – 230 and sectional reinforcement using Æ6 – 100. Beam structures using main reinforcement 2D16, 3D16 and 5D16 and sectional reinforcement using Æ10 – 220 and Æ10 – 170. Column structures with dimensions of 40 x 40 using 6D – 19 main reinforcement and shear reinforcement using Æ10 – 200. The foundation structure uses a pile with dimensions of 1,30 m x 1,30 m x 0,3 m, the main reinforcement in the x and y directions uses 7D16 and the shear reinforcement for the x and y directions use D10-200.
