Abstract
Tinggi aktivitas seismik di Indonesia menuntut penerapan sistem struktur yang mampu memberikan kinerja optimal terhadap beban gempa. Steel plate shear wall (SPSW) merupakan salah satu sistem penahan beban lateral yang efektif untuk meningkatkan performa seismik struktur. Penelitian ini bertujuan merencanakan struktur baja Gedung Hotel Patra Surabaya serta membandingkan performa SPSW tipe Unstiffened dan tipe Composite. Penelitian dilakukan melalui perencanaan struktur primer dan struktur sekunder, analisis pembebanan, pemodelan struktur tiga dimensi, perencanaan SPSW tipe Unstiffened pada Model 1 dan tipe Composite pada Model 2, perencanaan sambungan serta evaluasi kinerja struktur berdasarkan konsep Performance-Based Seismic Design. Evaluasi kinerja struktur menggunakan metode pushover analysis untuk meninjau parameter disipasi energi, gaya geser dasar, simpangan antar lantai, perpindahan atap, dan tingkat kinerja struktur. Berdasarkan analisis dilatasi, kedua model memerlukan lebar celah dilatasi sebesar 450 mm. Hasil komparasi menunjukkan bahwa Model 2 memiliki kapasitas disipasi energi yang lebih besar 5,21% pada arah X dan 12,33% pada arah Y untuk Gedung 1, dan sebesar 33,54% pada arah X dan 7,9% pada arah Y untuk Gedung 2. Pada gaya geser dasar, Model 2 memiliki gaya geser dasar lebih besar 22,05% pada arah X dan 19,16% pada arah Y untuk Gedung 1, dan sebesar 21,06% pada arah X dan 19,38% pada arah Y untuk Gedung 2. Terkait simpangan maksimmum, Model 2 memiliki nilai lebih kecil 0,64% pada arah X dan 7,98% pada arah Y untuk Gedung 1, dan sebesar 6,17% pada arah X dan 3,14% pada arah Y pada Gedung 2. Pada perpindahan atap, Model 2 memiliki nilai lebih kecil 6,07% pada arah X dan 1,37% pada arah Y untuk Gedung 1, dan sebesar 0,36% pada arah X dan 4,25% pada arah Y pada Gedung 2. Berdasarkan kriteria ASCE 41-13, kedua model struktur mencapai target kinerja yang disyaratkan, yaitu berada pada rentang Immediate Occupancy (IO) hingga Life Safety (LS).

Indonesia's high seismic activity necessitates structural systems capable of providing reliable seismic performance. Steel Plate Shear Wall (SPSW) is an effective lateral force-resisting system that enhances structural performance under earthquake loading. This study aims to design the steel structure of the Patra Hotel Surabaya and compare the seismic performance of Unstiffened SPSW and Composite SPSW systems. The study was conducted through the design of primary and secondary structural members, load analysis, three-dimensional structural modeling, SPSW design, connection design, and structural performance evaluation based on the Performance-Based Seismic Design (PBSD) concept. Model 1 employs Unstiffened SPSW, whereas Model 2 employs Composite SPSW. Structural performance was evaluated using pushover analysis by assessing energy dissipation capacity, base shear, inter-story drift, roof displacement, and structural performance level. The expansion joint analysis indicates that both models require an expansion joint width of 450 mm. Compared with Model 1, Model 2 demonstrates higher energy dissipation capacity by 5,21% in the X-direction and 12,33% in the Y-direction for Tower 1, and by 33,54% and 7.9%, respectively, for Tower 2. Base shear also increases by 22,05% and 19,16% for Tower 1, and by 21,06% and 19,38% for Tower 2 in the X- and Y-directions, respectively. Furthermore, Model 2 reduces the maximum inter-story drift by 0,64% and 7,98% for Tower 1, and by 6,17% and 3,14% for Tower 2 in the X- and Y-directions, respectively. Roof displacement is also reduced by 6,07% and 1,37% for Tower 1, and by 0,36% and 4,25% for Tower 2. According to ASCE 41-13, both models satisfy the required seismic performance objective, achieving performance levels ranging from Immediate Occupancy (IO) to Life Safety (LS).
