Abstract

The design of high-rise buildings required earthquake resistant planning because the arrival of earthquakes cannot be predicted with certainty in place and time, natural events can damage the structure. One of the planning concepts for earthquake resistant buildings is Performance-Based Design which is used in new or upgraded buildings that can guarantee occupant safety and readiness for use after an earthquake occurs. One of the approaches is pushover analysis based on the Applied Technology Council (ATC-40). In the results of the analysis of the planned buildings including the vertical and horizontal regular building categories, then the dual system structure requirements have met the specified criteria, the direction X and Y frame ratios are more than 25% (30% X direction & 45% Y direction). Floors drift with dynamic analysis of responsibility is stated to be safe in the provisions of the deviation between floors, which is 50 mm based on SNI 1726-2012, while the deviation between floors with pushover analysis is at the level of Immediate Occupancy (IO) performance based on ATC-40 Keywords: Dynamic Response Spectrum Analysis, Pushover Analysis, Applied Technology Council (ATC-40) Perancangan gedung – gedung bertingkat tinggi tentu diperlukan perencanaan tahan gempa karena kedatangan gempa tidak dapat diprediksi secara pasti tempat dan waktunya, kejadian bencana alam dapat merusak struktur. Salah satu konsep untuk perencanaan bangunan tahan gempa adalah Perencanaan Berbasis Kinerja (Performace- Based Design) yang digunakan pada bangunan baru atau upgrade dapat menjamin keselamatan penghuni, dan kesiapan pakai setelah gempa terjadi. Salah satu pendekatannya yaitu dengan analisis pushover berdasarkan Applied Technology Council (ATC-40). Pada hasil analisis gedung yang direncanakan termasuk pada kategorsi gedung beraturan vertical dan horizontal, kemudian syarat struktur sistem ganda sudah memenuhi kriteria yang ditentukan yaitu rasio frame X dan Y sudah lebih dari 25% (30% arah X & 45% arah Y). Simpangan antar lantai dengan analisis dinamik respon spektrum dinyatakan aman dalam ketentuan batas izin simpangan antar lantai yaitu sebesar 50 mm berdasarkan SNI 1726-2012 sedangkan simpangan antar lantai dengan analisis pushover berada pada level kinerja Immediate Occupancy (IO) berdasarkan ATC-40. Kata Kunci : Analisis Dinamik Respon Spektrum, Analisis Pushover, Applied Technology Council (ATC-40).
