Abstract
Studi desain berbasis kinerja seismik dengan menggunakan pendekatan Direct-Displacement Based Design metode Single-Degree-of-Freedom equivalent system yang berdasarkan ragam getar pertamanya telah banyak dilakukan di Indonesia, namun masih minim studi mengenai pengujian Direct-Displacement Based Design metode Multiple-Degree-of-Freedom equivalent system yang mampu menangkap pengaruh empat ragam getar. Penelitian ini berusaha melakukan pengujian daripada desain berbasis kinerja seismik menggunakan pendekatan Direct-Displacement Based Design metode Multiple-Degree-of-Freedom equivalent system yang diproposalkan Muho et. al (2020) dengan tiga buah subjek studi berupa struktur rangka baja terbresing eksentris tiga dimensi, dan sebagai verifikasinya menggunakan analisis nonlinear modal time history. Hasil uji menunjukkan bila Direct-Displacement Based Design metode Multiple-Degree-of-Freedom equivalent system masih memberikan akurasi yang baik, juga pada studi ini menunjukkan analisis nonlinear modal time history memberikan efisiensi waktu yang sangat baik dengan persentase galat yang masih dapat diterima.

Performance-based seismic design studies using the Direct-Displacement Based Design approach of the Single-Degree-of-Freedom equivalent system method, based on the first modes, have been widely conducted in Indonesia. However, there are still minimum studies testing the Direct-Displacement Based Design of the Multiple-Degree-of-Freedom equivalent system that can capture the influence of four modes. This research aims to test the seismic performance-based design using the Direct-Displacement Based Design approach of the Multiple-Degree-of-Freedom equivalent system method proposed by Muho et al. (2020). Three-dimensional eccentric braced steel frame structures are chosen as the study subjects. Verification is conducted using nonlinear modal time history analysis. The test results indicate that the Direct-Displacement Based Design of the Multiple-Degree-of-Freedom equivalent system still exhibits good accuracy. Additionally, this study reveals that nonlinear modal time history analysis provides excellent time efficiency with an acceptable percentage error.
