Abstract

Seorang perencana dituntut untuk dapat merancang dengan hasil berdaya guna tinggi, efisien, dan berestetika. Banyak aspek yang harus dipertimbangkan saat merancang suatu konstruksi, salah satunya adalah beban. Pengaruh beban gempa merupakan salah satu hal yang penting untuk dianalisis karena efek yang ditimbulkan terhadap bangunan dapat membahayakan manusia. Oleh karenanya diperlukan perancangan yang baik agar dapat mengurangi tingkat kecelakaan dan kerugian yang ditimbulkan.Dalam tugas akhir ini gedung yang ditinjau adalah gedung berlantai 3 yang merupakan gedung pendidikan Fakultas MIPA Universitas Tanjungpura, Pontianak. Perhitungan struktur mengacu pada SNI 2847-2013 untuk desain beton bertulang, SNI 1726-2012 untuk desain tehadap gempa dan SNI 1727-2013 untuk pembebanan pada struktur. Perhitungan struktur gedung ditinjau terhadap beban mati, beban hidup dan beban gempa. Perhitungan yang dilakukan meliputi elemen pelat, balok, kolom, dan pondasi. Digunakan aplikasi SAP2000 untuk membantu perhitungan gaya dalam elemen struktur. Pada struktur digunakan Sistem Rangka Pemikul Momen Biasa (SPRMB) karena berada pada wilayah kategori desain seismik A, dimana tidak ada aturan khusus yang harus dipenuhi. Digunakan pondasi tiang pancang karena sesuai untuk kondisi tanah lunak di Kota Pontianak dengan daya dukung yang sebagian besar didapat dari daya lekat tiang pada tanah.  Kata kunci :         Struktur, beton bertulang, SNI 2847-2013, SNI 1726-2012, SNI 1727-2013, pondasi

Abstract

Pontianak City has experienced a steady increase in tourist arrivals, which has resulted in a higher demand for temporary accommodation facilities. In response to this development, this study presents the structural design of an eight-story reinforced concrete hotel building located on Sepakat II Street in Pontianak City. The structure is designed using an Intermediate Moment-Resisting Frame (IMRF) system to ensure adequate performance under seismic loading conditions. The structural design process was carried out in accordance with the applicable Indonesian National Standards (SNI). Structural analysis was conducted using ETABS software to evaluate the building’s behavior under gravity and earthquake loads, while technical drawings were prepared using AutoCAD and SketchUp. The building utilizes concrete with a compressive strength of f’c = 30 MPa and reinforcing steel with a yield strength of fy = 420 MPa. The seismic performance of the structure was evaluated through several parameters, including mass participation ratios, inter story drift limits, natural period verification, and P-Delta effects. The analysis results show that the structural system satisfies all required performance criteria, indicating that the building is capable of resisting seismic forces safely and efficiently. The slab system consists of D10 main reinforcement bars and Ø8 shrinkage reinforcement bars, with slab thicknesses of 150 mm for the roof, 130 mm for typical floors (Levels 1–8), and 160 mm for stair landings. The primary beams (B1) have cross-sectional dimensions of 300 × 600 mm and are reinforced with D19 longitudinal bars, D13 shear reinforcement, and D19 torsional reinforcement. Secondary beams (B2) measure 200 × 400 mm and use D16 longitudinal bars, D13 shear reinforcement, and D16 torsional reinforcement. Columns have a uniform cross-section of 700 × 700 mm and are reinforced with 20D22 longitudinal bars and D13 transverse reinforcement. The foundation system consists of three types of pile foundations using 200 × 200 mm precast concrete piles with reinforced pile caps designed to accommodate varying structural loads.

Abstract

Conventional concrete materials derived from natural resources cause environmental problems. This encourages the development of concrete using recycled materials for sustainability reasons. One such material is shellfish, which is used to replace aggregates in concrete, both fine and coarse aggregates. This study conducted an experimental study using shellfish waste as a fine aggregate in a concrete mixture. Utilization of shellfish waste not only reduces environmental problems but can also provide economic value to construction, as well as an effort to conserve natural resources. Shellfish waste was obtained from the coast of Mempawah Regency. The planned test specimens were 15x15x15 cm cubes with a target quality of K225 kg/cm². The test specimens were made with a composition of sand with shellfish sand in proportions of 0%, 5%, 7%, 9%, and 100%. Physical properties of shellfish sand were tested, slump tests were conducted to determine the effect of shellfish sand on concrete viscosity, and concrete compression tests were conducted at the age of 28 days to determine the effect of shellfish sand on concrete strength. The compressive strength test results with 0% substitution = 246.22 kg/cm² or 24.15 MPa. 5% substitution = 211.98 kg/cm² or 20.79 MPa, resulting in a 5.79% decrease in quality. 7% substitution = 195.10 kg/cm² or 19.3 MPa, resulting in a 13.29% decrease in quality. 9% substitution = 176.14 kg/cm² or 17.27 MPa, resulting in a 21.72% decrease in quality. 100% substitution = 155.56 kg/cm² or 15.25 MPa, resulting in a 30.86% decrease in quality. The greater the substitution of the shell sand mixture, the greater the decrease in quality.
