ANALISIS PERANCANGAN STRUKTUR BETON BERTULANG UNTUK FUNGSI RENTAL OFFICE 30 LANTAI DENGAN PENEKANAN SISTEM RIGID FRAME BERKANTILEVER

Abstract

Abstrak _ Kota Makassar semakin berkembang ditandai dengan banyaknya bangunan berlantai banyak, termasuk fungsi perkantoran serta ide desain arsitektural bangunan cenderung memvariasikan struktur sebagai daya tarik desainnya, struktur bangunan menjadi perhatian utama.Penelitian ini membahas tentang analisis struktur rigid frame berkantilever gedung kantor sewa 30 lantai dengan material beton bertulang. Analisis bertujuan menentukan detail struktur yang tepat untuk bangunan tersebut dengan program SAP2000 v.14. Penelitian bersifat kuantitatif karena menentukan dimensi struktur. Adapun penelitian bersifat komparatif. Struktur penopang cantilevered slab diberi dua alternatif, yaitu model 1 dan model 2. Terhadap beban-beban nongempa, model 1 lebih stabil sebesar 3,2%-10,39% dari model 2. Terhadap beban-beban gempa, model 1 cenderung lebih stabil dengan selisih efisiensi terbesar 37,7%-45,4% pada beban gempa respon spektrum. Adapun tulangan kolom menggunakan tulangan utama D20 dan tulangan pengikat D12; balok menggunakan tulangan utama D25 dan tulangan pengikat D12; pelat lantai dan basement menggunakan tulangan D10; dan shear wall menggunakan tulangan D16 (arah 11) dan D20 (arah 22). Struktur penopang model 1 menggunakan tulangan yang sama dengan shear wall dan model 2 menggunakan tulangan yang sama dengan kolom. Jumlah tulangan utama dan jarak antartulangan beragam sesuai dimensi penampang elemen struktur. Kata kunci :  Beton Bertulang; Rental Office ; Rigid Frame; Kantilever; Detail Penulangan. Abstract _ Makassar City is increasingly characterized by a large number of multi-storey buildings, including office functions and building architectural design ideas that tend to vary the structure as an attractive design, the building structure is a major concern. reinforced concrete. The analysis aims to determine the exact structure details for the building with the SAP2000 program v.14. Research is quantitative because it determines the dimensions of the structure. The research is comparative. The cantilevered slab support structure is given two alternatives, namely model 1 and model 2. For earthquake loads, model 1 is more stable at 3.2% -10.39% of model 2. For earthquake loads, model 1 tends to be more stable with the greatest efficiency difference of 37.7% -45.4% in spectrum response earthquake load. The column reinforcement uses the main reinforcement D20 and reinforcement reinforcement D12; the beam uses the main reinforcement D25 and reinforcement reinforcement D12; floor plates and basements using D10 reinforcement; and the shear wall uses reinforcement D16 (direction 11) and D20 (direction 22). The support structure of model 1 uses the same reinforcement as the shear wall and model 2 uses the same reinforcement as the column. The number of main reinforcement and intermittent distances varies according to the cross-sectional dimensions of the structural elements.
