Abstract

Indonesia menjadi salahhsatu negara yanggberada di antara tiga lempeng bumi (Eurasia, Indoaustralia, dan Pasifik) sehingga rawan akan terjadinya gempa. Sehingga dalam perencanaan sebuah bangunan, beban gempa menjadi faktor penting didalamnya agar terhindar dari kerusakan akibat gempa. Berbagai material telah melalui pengujian dan penggunaan sebagai bahan konstruksi untuk bangunan tahan gempa, salah satunya baja canai dingin. Penelitian ini bertujuan untuk mengetahui besarnya beban lateral maksimum yang mampu ditahan, energi disipasi, dan kegagalan struktur agar dapat dianalisis kegagalan pada struktur portal canai dingin dengan panel dinding sebagai salah satu contoh struktur tahan gempa. Baja canai dingin berdimensi 58x106 cm yang digunakan penelitian ini adalah baja dengan profil hollow square dengan rincian 40.40.0,3 untuk kolom dan 20.30.0,3 untuk balok. Material multiplek tebal 4 mm digunakan sebagai panel dinding dengan variasi bukaan 0%, 25%, 50%, dan 100%. Drift rasio 1-13% dengan-interval-1% diberikan dengan pembebanannsiklikk(dua arah). Hasilppenelitianmmenunjukkan bahwaasemua bendaauji, nilai beban lateral maksimum dan energi disipasi tertinggi dimiliki benda uji berdinding panel bukaan 0%(S-T-0) dan nilai beban lateral maksimum dan energi disipasi yang terendah dimiliki benda uji yang tidak berdinding panel. Nilai beban maksimum dan energi disipasi benda uji berdinding panel dengan bukaan 50% (S-T-50) lebih rendah dibandingkan benda uji berdinding panel bukaan 25% (S-T-25). Disimpulkan jika bukaan panel dinding benda uji bertambah besar, berdampak pada energi disipasinya semakin kecil, dan beban lateral yang dapat ditahannya semakin kecil pula. Terjadi kegagalan struktur selama pengujian seperti kegagalan pada sambungan, sobek pada area sambungan, dan panel dinding mengalami retak.

Muhammad Rafly Setiaimani, Department of Civil Engineering, Faculty of Engineering, University of Brawijaya, April 2021. Impact of Multiplex Wall Panel Openings on the Dissipasion Energy under Cyclic Load of 2D Cold-Formed Steel Frame Structures, Academic Supervisor: Ir. Ananda Insan Firdausy, ST., MT., M.Sc and Dr. Eng. Devi Nuralinah, ST., MT. Indonesia is a country located between three earth plates, namely Eurasia, Indoaustralia and the Pacific. Which are rarely occurs for earthquakes. This can affect infrastructure development in Indonesia. So it is important to plan buildings that are resistant to earthquake loads in order to avoid losses such as damage to dwellings and other buildings. Therefore, a construction material that has been researched for earthquake resistance is needed and has been frequently used. One of them is cold rolled steel. The cold rolled steel used in this research has dimensions of 58 cm wide and 106 cm high, consisting of a hollow square profile with dimensions of 40.40.0.3 for columns and dimensions of 20.30.0.3 for beams. For joint plates between columns and beams, these profiles can be used too. For wall panels using multiplex material with a thickness of 4 mm. There are 4 types of portals in this study with variations in wall panel openings of 0%, 25%, 50% and 100%. In each of the variations of the openings there are 3 specimens that have codes such as: S-T-0, S-T-25, S-T-50 and S-T-100. ST-0 for test specimens that have panel walls and no openings, S-T-25 for test specimens that have panel walls and have an opening of 25%, S-T-50 for test specimens that have panel walls and have an opening of 50% and ST-100 for specimens that do not have panel walls. The loading given is cyclic loading (twoway) with a drift ratio of 1% to 13% and an interval of 1%. By reading the magnitude of the lateral load that occurs and the amount of horizontal displacement, this research is conducted to determine the maximum lateral load that can be withheld, the energy dissipation, and the structural failure of the specimen. The results showed that the test object which has panel walls and no openings (S-T0) has the biggest maximum lateral load value and the biggest energy dissipation and the test object without panel walls (S-T-100) has the smallest maximum load value and smallest energy dissipation. For test objects that have panel walls and openings of 50% (S-T-50) have a maximum load value and energy dissipation that is smaller than the test objects that have panel walls and there are 25% openings (S-T-25) which has a biggest maximum load value and biggest energy dissipation. This shows that the larger the wall panel opening on the test object, the smaller the energy dissipation, and the smaller the lateral load it can withstand. When observed visually, the cyclic loading test shows that there have been several structural failures in the specimen such as failure of joints in wall panels, tears in wall panels around the joints, and cracks in wall panels.
