Abstract

Makalah ini merupakan hasil studi numerik yang meneliti perilaku seismik terhadap link panjang dengan menggunakan pengaku diagonal pada bagian badan untuk meningkatkan kinerjanya, pada sistem struktur baja berpengaku eksentrik (EBF). Perilaku seismik ini mencakup kekuatan (strength), kekakuan (stiffeness), daktilitas (ductility) dan dissipasi energi (energy of dissipation). Penelitian ini bertujuan untuk meneliti perilaku link panjang dengan menggunakan pengaku diagonal pada bagian badan dibawah pembebanan statik monotonik dan siklik dengan kontrol perpindahan (displacement control), riwayat pembebanan yang diberikan dalam pengujian ini sesuai dengan standar pembebanan AISC 2010. Analisis dilakukan dengan pendekatan elemen hingga Non-Linier dengan menggunakan perangkat lunak komputer MSC/NASTRAN. Link dimodelkan sebagai elemen shell CQUAD yang ditumpu pada kedua ujungnya sedangkan beberapa nodal pada posisi pembebanan diperbolehkan untuk bertranslasi dalam satu arah saja (arah sumbu-y). Panjang link yang digunakan dalam analisa ini adalah 1555 mm penampang link profil WF 150.75. Perilaku link panjang dengan pengaku diagonal badan dibandingkan dengan perilaku link panjang standard yang direncanakan sesuai dengan ketentuan AISC 2010. Hasil analisis menunjukkan bahwa pengaku diagonal badan dapat meningkatkan kinerja link panjang dalam hal : kekuatan kekakuan dan dissipasi energi dalam menahan beban lateral. Namun, perbedaan perilaku antara link panjang dengan pengaku diagonal badan dan link panjang yang direncanakan sesuai standar AISC tidak begitu signifikan.

Abstract

Steel plate shear walls are structural elements that can increase lateral capacity due to earthquake loads. In certain conditions, the presence of openings such as doors and windows is often avoided in shear wall areas because they have the potential to interfere with the performance of the shear wall plate. If there is limited area for openings due to needs or architectural reasons, the shear wall area can be used as an alternative. This study aims to evaluate the effect of openings on shear wall plates through a finite element-based numerical study. There are three test specimen models, two of which are plates with openings and one test specimen is a full plate used as a comparison. Loading is given statically monotonically until it reaches a displacement of 40 mm, or equivalent to a 4% drift. The analysis results show that openings significantly reduce the plate's capacity to withstand lateral loads by more than 50%.

Abstract

Indonesia is a country that has a very high level of seismicity. It is necessary to plan a building structure that can withstand the earthquake load. Indonesia has adopted guidelines on earthquake resistance planning procedures for buildings and non-buildings. This guideline uses the Performance-Based Seismic Design (PBSD) concept. Performance-Based Plastic Design (PBPD) is a structural analysis with the concept of energy methods which was initially used on steel structures. For reinforced concrete structures this method can also be used using the C2 coefficient. To determine the performance level of structures designed using the Performance-Based Plastic Design method, an analysis of the five-story reinforced concrete structure was carried out. Next, the structure will be analyzed using pushover loads. From the structural performance analysis, the structural ductility value based on Performance-Based Plastic Design (PBPD) was 3.014. The performance level is based on the capacity spectrum at the immediate occupancy level.
