Abstract

This study examines the minimum effective separation distance between buildings necessary to avert structural damage from building pounding in Padang City, an area particularly vulnerable to seismic events. The study examines 45 structures throughout five districts, classified into three categories according to their height-to-width (H/L) ratio: (0.5–1.0), (1.1–1.5), and (1.51–2.0). Three pairs of ground acceleration records—Imperial Valley-06, Tokachi-Oki Aftershock, and Tokachi-Oki Mainshock—were selected and calibrated to align with the target response spectrum of Padang City using linear time-history analysis. The research assesses structural displacement capacity and drift ratio to ascertain the necessary minimum separation distances. The findings reveal that the minimum separation distance for Category A (H/L: 0.5–1.0), Category B (H/L: 1.1–1.5), and Category C (H/L: 1.51–2.0) spans from 40 cm to 48.4 cm, with a suggested practical separation of 50 cm per building. A separation distance of 1 meter is recommended to reduce the risk of structural collisions during earthquakes. These findings serve as a technical reference for urban planners, engineers, and legislators, facilitating safer building designs, enhanced seismic resilience, and diminished structural damage in earthquake-prone regions.

Abstract

One of the widely implemented seismic-resistant structural systems is the Eccentrically Braced Frame (EBF) system, which combines elastic stiffness with high ductility through a specialized component known as the link. The link is designed to undergo plastic deformation and dissipate seismic energy, while the other structural elements remain within the elastic range. This mechanism makes EBF an effective solution for enhancing the seismic performance of buildings, particularly in regions with high seismic activity. This study aims to design a five-story steel structure located in Padang City by applying the EBF system using an eccentric bracing configuration with short links. The design process focuses on the primary structural elements, namely beams and columns, in accordance with applicable Indonesian national standards, specifically SNI 1729:2020. In addition, SNI 1726:2019 and SNI 1727:2020 are used for seismic and gravitational load analysis, respectively. The design of the link component refers to AISC 341-16, particularly for determining link categories and the required stiffener thickness. The results of this study include detailed drawings of the designed links based on the aforementioned codes, along with a discussion on the significance of using eccentric bracing in influencing the structural response

Abstract

Concrete beams on structures sometimes have to be covered for utility lines. For the case of concrete beams with openings, special calculations must be made because the lengths of the dimensions no longer have the same dimensions. One of the approaches is with the strut and tie model. Currently, there are no standard provisions in the manufacture of the strut and tie model, as it is an approach to calculating in areas where Bernoulli's law does not apply. In order to facilitate the creation of a strut and tie model, the study used a simple software tool called BESO2D. The number of samples of the test model is 4 variations with different position and size of the hole. The dimensions of the beam used are 150x300 mm with a length of 2000 mm. Each of the beams will be given a reinforced based on the working load and from the strut and tie model frame. The behavior of each beam will be analyzed using the software of the finite element method to specific concrete named ATENA.

Abstract

Pemanfaatan lahan yang terbatas menghasilkan desain bangunan/gedung yang tak beraturan. Bangunan/gedung tak beraturan akan memiliki perilaku serta kinerja tersendiri dalam menerima beban. Karena itu diperlukan sistem struktur dinding geser dalam memerima beban gempa. Posisi dinding geser yang tepat akan menghasilkan perilaku dan kinerja yang ideal bagi struktur. Tujuan penelitian ini untuk menentukan posisi dinding geser yang ideal dalam menerima bebaan gempa. Metode penelitian ini adalah studi numerik dengan analisis pushover menggunaka program ETABS V 16. Terdapat satu model tanpa dinding geser dan lima model dengan posisi dinding geser yang berbeda-beda. Layout model penelitian ini berbentuk L berlokasi di Kota Padang dengan kondisi tanah sedang. Hasil penelitian menunjukkan posisi dinding geser model 1 yang berada pada ujung bangunan memiliki perilaku yang ideal dalam menerima beban gempa berdasarkan pengecekan persyaratan SNI 1726 2019 dan memiliki tingkat kinerja kategori damage control berdasarkan ATC-40 1996 yang berarti bahwa bangunan mengalami kerusakan tetapi tidak diperkenankan mengalami keruntuhan yang menyebabkan korban jiwa manusia (resiko korban jiwa sangat rendah).
