Abstract

AbstractThe condition of the tectonic arrangement is so complex that the Indonesian territory becomes an active seismic area with a high frequency of earthquakes. Considering that earthquakes can cause casualties and damages to infrastructure, it is necessary to analyze the structure of the building using the right method. This study aims to analyze the structure in needed to fulfill the safety requirements based on SNI 1726:2019 with the interstory drift and ATC-40 which is observed based on the maximum total drift and see the mechanism of the collapse that occurs. Structural analysis was carried out using the pushover anaysis method added with a structural analysis program. From the analysis results, the displacement values obtained by the ATC-40 method are 63,939 mm in the x – direction and 85,299 mm in the y – direction. The performance level generated based on this method is immediate occupancy where the structural and non-structural elements experience minimum damage so that the building remains safe for reuse. The structure collapse mechanism shows the concept of a strong column weak beam mechanism. The interstory drift that occurs is still in the safe category because it does not exceed the interstory drift, which is 42 mm. Key words:pushover analysis, performance level, failure mechanism, interstory drift. AbstrakKondisi tatanan tektonik yang begitu komplek menyebabkan wilayah Indonesia menjadi kawasan seismik aktif dengan frekuensi kegempaan yang tinggi. Mengingat gempa bumi dapat mengakibatkan korban jiwa dan hancurnya infrastruktur sehingga diperlukan analisis terhadap struktur bangunan tersebut dengan menggunakan metode yang tepat. Penelitian ini bertujuan untuk menganalisis struktur dalam memenuhi persyaratan keamanan berdasarkan SNI 1726:2019 dengan tinjauan simpangan antar tingkat dan ATC-40 yang ditinjau berdasarkan maximum total drift serta melihat mekanisme keruntuhan yang terjadi. Analisis struktur yang dilakukan menggunakan metode pushover analysis dengan bantuan program analisis struktur. Dari hasil, didapatkan nilai displacement dengan metode ATC-40 sebesar 63,939 mm arah – x dan 85,299 mm arah – y. Level kinerja yang dihasilkan adalah immediate occupancy dimana elemen struktural dan non-struktural mengalami kerusakan minimum sehingga bangunan tetap aman digunakan kembali. Mekanisme keruntuhan struktur menunjukkan konsep mekanisme strong column – weak beam. Simpangan antar tingkat yang terjadi masih dalam kategori aman karena tidak melebihi simpangan antar tingkat izin yaitu 42 mm. Kata kunci: analisis pushover, level kinera, mekanisme keruntuhan, simpangan antar tingkat.

Abstract

AbstractPlate girder is a flexible structural component that composed from several plate elements. Basically, plate girder is a beam with a large cross-sectional size and a long span. Plate girder is an alternative if the largest hot rolled steel profile is insufficient to carry the working load due to its long span.This research will plan the main structure, that is girder plate for a multi-storey building with a hanging system (suspension building), and also plan the complementary components. Generally, the implementation steps of the process are collecting planning data, calculating loading, calculating the forces those worked on the structure using SAP2000, after that, designing the girder plate profile, and other components such as joint design and stiffener design, so that safe structural details are obtained.In the design that has been done, the column dimensions are obtained (h = 1500, bf = 500, tw = 8, tf = 30) mm, beam (h = 1500, bf = 450, tw = 8, tf = 30) mm, transverse stiffener ( bp = 120, tp = 8, h = 1440) mm, column-beam joints (Db = 24mm, n1 = 36 bh, n2 = 78 bh), beam-beam joints (Db = 24mm, n1 = 32 bh, n2 = 70 bh), splice joints (Db = 24mm, n1 = 26 bh, n2 = 16 bh), and base plate connections (Db = 24mm, n1 = 10 bh). Based on the design, the profile and components are quite safe to use.Keywords : Girder Plate Beam, Steel Structure, Building Structure Design, Suspension Building.

Abstract

AbstractIndonesia is an area with a high level of earthquake vulnerability. One of the efforts to anticipate these impacts is to meet the needs of earthquake-resistant buildings. In this case, it is necessary to carry out a comprehensive planning and evaluation of earthquake-resistant buildings by taking into account the lateral forces caused by earthquake loads in accordance with the latest regulations. This research takes a case study in Building B of the Muhammadiyah Metro General Hospital. In planning, the structure of the building still uses the old regulations, namely SNI 1726-2012, SNI 1727-2013, and SNI 2847-2013. Meanwhile, currently the latest planning standards have been implemented, namely SNI 1726-2019, SNI 1727-2020, and SNI 2847-2019, so it is necessary to evaluate the strength of the structure using the latest regulations. This study aims to compare the results of evaluating the strength of high-rise buildings due to the influence of earthquake loads and without earthquake loads using the dynamic response spectrum analysis method. Based on the results of the study, it was concluded that the building structure was not strong enough to withstand earthquake loads, and there was a significant difference between conditions without earthquake loads and with the influence of earthquake loads. Keywords: Response Spectrum Analysis, Earthquake Resistant Building, Evaluation of Structural Strength AbstrakIndonesia merupakan wilayah dengan tingkat kerawanan gempa yang tinggi. Salah satu upaya untuk mengantisipasi dampak tersebutadalahdengan memenuhi kebutuhan bangunan tahan gempa. Dalam hal ini perlu dilakukan perencanaan dan evaluasi yang menyeluruh terhadap bangunan tahan gempa dengan memperhitungkan gaya lateral yang diakibatkan oleh beban gempa sesuai dengan peraturan terbaru.Penelitian ini mengambil studi kasus pada Gedung B Rumah Sakit Umum Muhammadyah Metro. Dalam perencanaannya, struktur gedung tersebut masih menggunakan peraturan lama yaitu SNI 1726-2012, SNI 1727-2013, dan SNI 2847-2013. Sedangkan untuk saat ini telah diberlakukan standar perencanaan terbaru yaitu SNI 1726-2019, SNI 1727-2020, dan SNI 2847-2019, sehingga perlu dilakukan evaluasi kekuatan struktur dengan menggunakan peraturan terbaru tersebut.Penelitian ini bertujuan untuk mengetahui perbandingan hasil evaluasi kekuatan struktur gedung bertingkat akibat pengaruh beban gempa dan tanpa beban gempa menggunakan metode analisis dinamik respon spektrum. Berdasarkan hasil penelitiandisimpulkan bahwa struktur gedung tidak cukup kuat untuk menahan beban gempa, dan terdapat perbedaan yang signifikan antara kondisi tanpa beban gempa dan dengan pengaruh beban gempa.
