Abstract

Pembangunan konstruksi teknik sipil mengalami perkembangan yang sangat pesat seiring dengan berkembangnya zaman sehingga menuntut kita lebih kreatif dalam perancangan struktur baik dalam bentuk bangunan beraturan maupun tidak beraturan yaitu, bangunan setback dan bangunan soft story. Di Indonesia, tantangan yang dihadapi dalam kontruksi gedung bertingkat adalah adanya resiko akibat gempa. Salah satu metode untuk menganalisis beban gempa adalah analisis pushover. Analisis pushover merupakan prosedur analisis untuk mengetahui perilaku keruntuhan suatu bangunan terhadap gempa. Penelitian dilakukan untuk mengetahui seberapa besar pengaruh setback dan soft story yaitu bangunan tanpa dinding pengisi pada lantai dasar terhadap kinerja struktur akibat beban gempa berdasarkan hasil kurva pushover. Stuktur bangunan dimodelkan sebagai portal 2 dimensi yang tanpa adanya dinding pengisi pada lantai dasar yaitu terdiri dari 4 model rangka penuh, setback1, setback2, dan setback3. Hasil analisis dalam penelitian ini menunjukkan bahwa kontribusi dinding pengisi yang terbuat dari dinding bata mempengaruhi kekakuan lateral struktur, serta dengan dikuranginya setback pada struktur bangunan mengakibatkan nilai kekakuan semakin kecil sehingga nilai daktilitas semakin besar. Pada struktur gedung rangka penuh dan setback1 lunak kondisi bangunan sudah mengalami rusak parah atau runtuh saat terjadi gempa kuatdikarenakan terbentuknya sendi plastis pada kolom lantai pertama.  Kata Kunci : Analisis Pushover, Dinding Pengisi, Setback, Soft Story  ABSTRACT The construction of civil engineering construction has developed very rapidly along with the development of the era so it demands that we are more creative in the design of structures both in the form of irregular and irregular buildings ie, setback building and soft story building. In Indonesia, the challenge faced in the construction of multi-storey building is the risk caused by the earthquake. One method to analyze earthquake loads is pushover analysis. Pushover analysis is an analytical procedure to determine the collapse behavior of a building against earthquake. The research was conducted to find out how big the effect of setback and soft story that is building without wall filler on the ground floor to the structure performance due to earthquake load based on the result of pushover curve. The structure of the building is modeled as a 2-dimensional portal without the filler wall on the ground floor consisting of 4 full frame models, setback1, setback2, and setback 3. The results of the analysis in this study indicate that the contribution of wall filler made of brick walls affect the lateral stiffness of the structure, as well as with the reduced setback on the structure of the building resulting in smaller stiffness value so that the greater the ductility value. In full skeletal structure and soft setback1 the condition of the building has been severely damaged or collapsed during a strong earthquake due to the formation of plastic joints in the first floor column. Keywords: Pushover Analysis, Setback, Soft Story, Wall Filler
