Abstract

Eccentrically Braced Frames (EBFs) are earthquake-resistant steel structures with excellent shear capacity and ductility. During earthquakes, the EBF link yields first, protecting other structural elements. Traditionally, the link is integrated with the main beam and separated by bracing. However, if the link is damaged, replacing the entire beam becomes necessary. To address this, a vertical link design allows for link replacement without altering the beam section. This study evaluates two vertical link options: a Wide Flange (WF) link section and a Hysteretic Steel Damper (HSD) type Metallic Yielding Damper. Results suggest the WF link is preferable due to superior shear capacity and energy dissipation compared to the HSD link. The findings recommend the WF link for vertical link EBFs to optimize earthquake performance.

Abstract

Runway construction on soft soil presents significant engineering challenges due to excessive settlement, which can affect structural stability and long-term performance of transportation infrastructure. This study investigates the settlement of a runway in Sumbawa, Indonesia using the Finite Element Method (FEM) in Plaxis 2D. The Hardening Soil Model was applied to realistically capture nonlinear soil behavior. Input parameters were derived from a series of N-SPT data and laboratory test results. The findings indicate that during the operational phase, the maximum and minimum settlement were 307.1 mm and 2.491x10-3 mm, respectively. Meanwhile, consolidation-induced settlement reached a maximum of 357.97 mm and a minimum of 10.6 mm. The distribution of total settlement along the runway varied depending on soil characteristics. Sections with predominantly clayey soil exhibited greater settlement, whereas areas with sandy soil experienced significantly lower settlement.
