“…Salah satu faktor yang memengaruhi struktur dalam menerima beban yaitu konfigurasi struktur, dimana bangunan yang berkonfigurasi teratur lebih baik dalam menahan gaya gempa sehingga kerusakan struktur dapat dihindari [1] [2]. Selain itu, besarnya gaya gempa juga memengaruhi respons struktur yang terjadi diakibatkan karena gaya gempa akan diterima oleh dasar bangunan [3] [4]. Dari gaya gempa yang diberikan pada struktur, dapat ditentukan respons dan kinerja struktur pada setiap wilayah Indonesia yang mewakili wilayah dengan resiko gempa rendah sampai dengan tinggi.…”

[ID] Indonesia merupakan negara dengan resiko gempa tinggi, hal ini diakibatkan oleh pertemuan lempeng-lempeng tektonik utama dan lempeng kecil lainnya yang mengelilingi Indonesia. Setiap wilayah indonesia memiliki tingkat resiko gempa yang berbeda-beda, mulai dari resiko gempa rendah hingga resiko gempa tinggi. Tujuan dari penelitian ini adalah mengetahui perbandingan respons dan kinerja struktur suatu bangunan gedung di beberapa wilayah yang mewakili tingkat resiko gempa rendah hingga tinggi. Adapun wilayah-wilayah yang ditinjau dalam penelitian ini yaitu wilayah Pontianak, Palembang, Jakarta, Bandar Lampung, dan Palu. Analisis dilakukan pada bangunan beton bertulang empat lantai dengan dinding geser dengan menggunakan bantuan program SAP 2000 guna mendapatkan repons dan kinerja struktur. Hasil respons struktur dari penelitian menunjukkan nilai simpangan lateral lantai dari yang terbesar hingga terkecil yaitu dimulai dari wilayah Palu, Bandar Lampung, Jakarta, Palembang, dan Pontianak. Wilayah Palu memiliki nilai simpangan lateral lantai yang terbesar yaitu 23,745 mm dan 23,690 mm untuk arah X dan Y sedangkan wilayah Pontianak memiliki nilai simpangan lateral lantai terkecil dengan besar simpangan lateral 7,571 mm dan 7,439 mm untuk arah X dan Y. Berdasarkan analisis pushover didapatkan level kinerja struktur memiliki level kinerja B untuk Wilayah Palu dan IO untuk wilayah lainnya. [EN] Indonesia is a country with a high risk of earthquake due to the meeting of the main tectonic plates and other small plates that surround Indonesia. Each area in this country has a different level of earthquake risk, ranging from low to high earthquake risk. This study aims to compare the response and structural performance of buildings in some areas with low to high earthquake risk levels. The areas covered Pontianak, Palembang, Jakarta, Bandar Lampung, and Palu. The analysis was carried out on a four-story reinforced concrete with shear walls using the SAP 2000 program to obtain the response and performance of the building structure. The results of the structural response showed the value of the floor lateral deviation from the largest to the smallest, starting from Palu, Bandar Lampung, Jakarta, Palembang, and Pontianak. Pulu has the largest floor lateral deviation values of 23.745 mm and 23.690 mm for the X and Y directions, while Pontianak has the smallest floor lateral deviation values of 7.571 mm and 7.439 mm for the X and Y directions. Based on the pushover analysis, the structure has a performance level of B for Palu areas and IO for other areas.

“…Pushover analysis is one of the practical and effective methods to determine seismic capacities of structures in the design and evaluation process (Hsiao et al, 2015;Estêvão and Oliveira 2015;Krawinkler and Seneviratna, 1998). This analysis method was developed to understand the nonlinear behaviour characteristics and performance of structures under horizontal loads (Chopra and Goel, 2002;Elnashai, 2001).…”

In this study, we present the effect of various negativity parameters on steel structures that cause postearthquake damage based on performance-based assessment. In accordance with this purpose, eigenvalue and pushover analysis are carried out for different negativity parameters such as number of story, soft story, short column, hill-slope effect and irregularity in plan for a sample steel structure in this study. Structural models were created over the reference building to cover each negativity parameter within the scope of this study. Natural vibration period, base shear force, target displacements for damage estimation and stiffness values are obtained for each structural model separately. The comparisons with the reference building model results are made. The effect to behavior of structures is determined and a reduction coefficient is proposed, for each negativity parameter, respectively. The proposed coefficients can be used to determine the risk priority in steel structures. It was concluded that each negativity parameter considered in this study reduces the behavior of the building under the effect of earthquakes.

“…A regularly configured building is better at resisting earthquake forces, preventing structural damage [4] [5]. As a result of the earthquake force being absorbed by the building's base, the magnitude of the earthquake force also influences how the structure reacts [6] [7]. The response and performance of the structure in each Indonesian region, which represents regions with low to high earthquake risk, can be calculated from the earthquake force applied to the structure.…”

South Sulawesi is one of the areas prone to earthquakes. The Walanae Fault extends from the Makassar Strait to the Bone Bay. This fault stretches along the Walanae River and passes through the districts of Pinrang, Sidrap, Bone, to the Gulf of Bone. The structure of the stilt house is one that is earthquake resistant because it does not directly receive earthquake energy. Traditional techniques on the structure of houses on stilts in Bima district for earthquake resistance researched by Agus Hariyanto, Sugeng Tiyadi, and Andy Widyowijatnoko, stated that the local structural technique, namely pa’a which was empirically developed by the community over the years can reduce the vulnerability of houses. against earthquakes. This technique turns out to have similarities with the framework of the Bugis-Makassar stilt structure, which is classified as a rigid joint truss system. The purpose of this study was to determine the response and performance of the Bugis-Makassar stilt house structure in the Bone region which represents a high level of earthquake risk. The analysis was carried out on the structure of a Bugis stilt house in Bone using the ETABS v.20 program to obtain the response and performance of the structure. The results of the structural response from the study indicate the value of the lateral deviation of the floor. The Bone region has a floor lateral deviation of 3.64 mm and 6.45 mm for the X and Y directions. Based on the pushover analysis, the structure performance level has a B performance level for the Bone Region.
