EVALUASI LEVEL KINERJA GEDUNG 6 LANTAI DENGAN METODE NON-LINEAR TIME HISTORY ANALYSIS
Abstract
AbstractIndonesia is a ring of fire area where earthquakes frequently occur. By realizing this, buildings in Indonesia need to calculate earthquake loads based on SNI 03-1726-2019 to minimize victims due to building collapse when earthquakes occur.
It is also necessary to evaluate the performance level of a building, in this case a 6-storey building located in the Malang area. For determining the level of performance, a method called Non-Linear Time History Analysis is used. In this calculation used San Fernando, Kobe and Landers ground motion.
Based on the results from the evaluation using the Non-Linear Time History method got the maximum drift story 0.137 m that occurs in Kobe ground motion. So that the maximum total drift Dt / H is 0.137 / 21.95 = 0.0063 <0.01. Based on these results, the building performance level includes IO (Immediate Occupancy). AbstrakIndonesia termasuk daerah ring of fire dimana suatu daerah yang sering terjadi gempa. Dengan menyadari hal tersebut, bangunan-bangunan yang ada di Indonesia perlu memperhitungkan beban gempa yang ada berdasarkan SNI 03-1726-2019 untuk meminimalisir korban akibat keruntuhan bangungan yang terjadi akibat gempa.
Karena itu perlu juga untuk mengevaluasi level kinerja suatu gedung dalam hal ini gedung 6 lantai yang terletak di daerah Malang. Pada gedung ini untuk dapat diketahui level kinerjanya, maka, digunakan metode yang bernama Non-Linear Time History Analisis. Ground motion yang dipakai adalah San Fernando, Kobe dan Landers
Berdasarkan hasil yang diperoleh dari evaluasi dengan metode Non-Linear Time History Analisis ini adalah maximum drift story terbesar adalah 0,137 m yang terjadi pada ground motion Kobe. Sehingga Maximum total driftnya Dt/H adalah 0,137/21,95 =0,0063<0,01. Berdasar hasil tersebut lever kinerja gedung termasuk IO (Immediate Occupancy).Downloads
