Abstract

Apartemen Tamansari Emerald merupakan salah satu gedung tinggi di Surabaya dengan 42 lantai tower dan podium serta 1 semi basement. Gedung Apartemen Tamansari Emerald Surabaya direncanakan menggunakan sistem ganda yang mengacu pada peta gempa Indonesia tahun 2012 dengan peraturan SNI 1726-2012. Seiring berjalannya pembaharuan pada peta gempa terbaru dan peraturan terbaru, perlu adanya evaluasi dengan peta gempa Indonesia tahun 2017 dan peraturan SNI 1726-2019. Berdasarkan hasil evaluasi struktur eksisting dengan peraturan dan peta gempa terbaru, sebanyak 13 lantai dari gedung tersebut mempunyai drift melebihi dari simpangan ijin sebesar 70mm dengan simpangan terjadi paling besar 78,4mm. Untuk mengatasi masalah tersebut perlu dilakukan modifikasi sistem struktur menggunakan sistem outrigger dan belt-truss. Lokasi optimal outrigger dan belt-truss berada di tengah ketinggian bangunan, sehingga simpangan antar lantai struktur memenuhi syarat ijin. Perhitungan struktur mengacu pada peraturan yang terbaru yaitu SNI 2847-2019, SNI 1729-2015, SNI 1726-2019. Sedangkan perhitungan pembebanan mengacu pada SNI 1727-2013. Proses x perhitungan struktur meliputi analisis pembebanan, permodelan struktur dengan ETABS 18, analisis gaya dalam, kontrol penulangan. Pemilihan sistem struktur pada bangunan harus mengutamakan aspek kekuatan dan efisiensi. Berdasarkan hasil analisa perhitungan dan beberapa percobaan, sistem outrigger dan belt-truss dipasang di lantai 20 dan sistem outrigger di lantai 10. Dimana simpangan antar lantai akibat perubahan nilai percepatan peta gempa bisa tereduksi dan sudah memenuhi ketika memakai sistem outrigger dan belt-truss. balok outrigger yang digunakan memiliki ketebalan 300 mm dan bracing belt-trus dengan profil HSS 300 × 16.

The design of earthquake-resistant building structures is one of the important things to analyze, especially for tall buildings that are in areas that are often hit by large earthquakes. Given that the Indonesian archipelago is located in an area prone to earthquakes, a good building design is needed to anticipate earthquake disasters and be able to limit building damage due to mild to moderate earthquakes so that it can still be repaired and the losses incurred are not too large. The discovery of the latest faults in Indonesia, one of which is the Kendeng Fault located in the city of Surabaya, has led to a review of SNI 1726-2012 so that SNI 1726-2019 is compiled and used in the calculation of the earthquake in this final project. The choice of a building structure system must prioritize the aspects of strength and efficiency, the Tamansari Emerald Apartment which has 42 floors will use a combination of a concrete outrigger and belt truss for strengthening the main structure of the building. Outrigger is a structural element consisting of one-floor beams which function to increase the overall rigidity of the building so as to reduce the period and deviation of the building that occurs. The process of calculating the structure includes loading, modeling, drawing with the Revit assistant program. Changes in the response spectrum value will affect the level of performance of the structure in accommodating the working earthquake load. Based on these changes, the structures that have been designed or built must be re-evaluated according to the latest regulations. After xii evaluating the latest earthquake maps, it is known that the Tamansari Emerald building has drift occurs in the building that exceeds the allowable deviation. Based on the analysis results, the outrigger and belt truss systems were installed on the 20th and 10th floors. Where the deviation between floors due to changes in the value of the acceleration of the earthquake map has met when using the outrigger and belt-truss systems. The outrigger beam used has a thickness of 300 mm and a belt brace with an HSS profile of 300x16.
