Abstract

The 5-storey building with 20 meters high and is located in Jakarta, a building that functions as a shop and residence. As a high-rise building, earthquake analysis of the building is required to determine the seismic pattern using the response spectrum method. The spectrum response method is used to determine the structural performance and compare static analysis and dynamic analysis based on SNI 1726-2019. Then the results obtained for each frame use a combination of cases (static + seismic), for displacement review, there is the highest drift on the 5th floor of 37.04 mm, and the highest drift value on the 5th floor of 4.57x10-3 mm. The internal force in the sample column obtained the same results in story 1 column C1 and C2 of 59.57 kN at Fx, Fy of 4.72 kN and moment of 5.01 kN-m, through a combination (static + seismic). The value of the sample beam on the 3rd floor has the highest value on B1, the Fx value was 4.73x10-14 kN, Fy was 9.09 kN, and the moment was 13.88 kN-m.

Abstract

Penggunaan limbah sebagai bahan substitusi dalam pembuatan beton ramah lingkungan menjadi alternatif yang relevan untuk mengatasi masalah lingkungan dan sumber daya yang semakin menipis. Penelitian ini berfokus pada penggunaan limbah keramik granit, limbah beton, dan cangkang kerang (Grabeka) sebagai pengganti agregat kasar dan halus dalam campuran beton. Pengujian dilakukan untuk menilai kekuatan tekan beton pada umur 28 hari serta analisis biaya dibandingkan dengan beton konvensional. Hasilnya menunjukkan bahwa beton dengan campuran limbah Grabeka mampu mencapai kekuatan tekan optimal sebesar 35,09 Mpa. Selain itu, penggunaan zat aditif Sikament NN mempercepat proses pengerasan, sehingga beton dengan agregat daur ulang menjadi lebih efisien.
