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.

Abstract

This study investigates the seismic performance of slit link configurations using wide-flange (WF) sections within eccentrically braced frames (EBFs), addressing the limited application of slit geometries in practical steel construction. The objective is to evaluate the influence of slit shape and width on shear strength, ductility, and energy dissipation, while ensuring damage localization within the link element. Six analytical models were developed, including conventional links (CV and CV-ST) and slit variants (SL-1 to SL-4), and analyzed through nonlinear finite element simulations in ABAQUS under the AISC 341-22 cyclic loading protocol. The analysis focused on stress distribution, hysteretic response, backbone curve stability, and energy dissipation. Results show that conventional links provide higher peak shear strength and energy absorption but transmit stresses into adjacent members, increasing repair complexity. In contrast, slit links confine plastic deformation within the link region, enhancing ductility and repairability at the expense of reduced strength. Among the slit variants, the parabolic slit (SL-4) demonstrated smoother stress redistribution and improved cyclic stability compared to rectangular slits. The novelty of this research lies in embedding slit geometries directly into WF profiles, offering a cost-effective fuse mechanism that bridges theoretical slit damper concepts with real-world EBF applications.
