Abstract

Generally the concrete behavior can be observed by the experimental analysis. However, since the computer technology development has been increased rapidly, the computer simulations are also able to represent the detail behavior of concrete. This paper presents the modeling response of concrete material subjected to biaxial loading using finite element method software based. The plain concrete plates with dimensions 200mm x 200mm x 50mm and 150mm x 150mm x 50mm are analyzed using various combinations of biaxial loading. The results of the biaxial load combinations are covering the three non-linear regions of compression–compression, compression–tension, and tension–tension. The results of finite element analysis are also show good agreement to the experimental results that been taken from the previous study. The comparison results the difference between analytical and experimental study are less than 5%. Therefore, the concrete material model based on this finite element method software can be used to simulate the responses in the real condition.

Abstract

The use of stiffening elements in steel plate shear wall (SPSW) systems enhances lateral stiffness and energy dissipation capacity; however, it also significantly increases material and labor costs due to the complexity of fabrication and installation. As an alternative, the Corrugated Steel Plate Shear Wall (CoSPSW) system has been proposed as a more efficient and practical solution that maintains sufficient stiffness and strength without requiring additional stiffeners. This study investigates the structural performance of CoSPSWs with varying corrugation geometries using the finite element method. The analysis focuses on the influence of the corrugation angle on the overall structural behavior, including buckling stability, lateral stiffness, ultimate strength, and energy dissipation capacity. Nonlinear finite element simulations were conducted using ABAQUS software to capture the influence of geometric nonlinearities under lateral cyclic loading. The results show that increasing the corrugation angle significantly improves lateral stiffness and energy dissipation capacity, while maintaining stable post-buckling behavior. An optimal corrugation angle of approximately 60° provides the maximum strength and ductility among the specimens. This study contributes to understanding the behavior of corrugated steel shear walls and provides valuable insights for the design of efficient, cost-effective steel structures.

Abstract

Shear walls serve as the primary structural elements for resisting lateral loads induced by earthquakes; however, slender shear walls remain susceptible to shear failure and buckling, particularly in structures designed according to older design codes. One strengthening technique that has gained increasing attention is the application of Ultra-High Performance Fiber Reinforced Concrete (UHPFRC) overlays, which offer high strength and effective crack control capabilities. This study aims to analyze the cyclic behavior of slender shear walls strengthened with a two-layer UHPFRC overlay with a total thickness of 40 mm using a finite element method based on the Concrete Damage Plasticity (CDP) model implemented in Abaqus. The numerical model is validated using experimental data from conventional reinforced concrete shear walls and UHPFRC-strengthened shear walls by comparing force–displacement responses, hysteresis curves, and tensile damage (Damage) distributions. The validation results indicate that the numerical model accurately captures the structural response, as evidenced by the close agreement in maximum displacement and damage mechanisms, with displacement differences of 2.97% for the conventional shear wall and 0.18% for the UHPFRC-strengthened shear wall. Parametric analysis shows that the UHPFRC overlay significantly increases the maximum load capacity from 328.22 kN to 525.37 kN, enhances the initial stiffness and first-yield capacity, and reduces the maximum displacement from 127.79 mm to 112.50 mm. Furthermore, the UHPFRC-strengthened shear wall exhibits a more stable post-peak response, fuller hysteresis loops, higher energy dissipation capacity, and more localized and gradually developing tensile damage compared to the conventional shear wall. These results demonstrate that a 40 mm-thick two-layer UHPFRC overlay effectively improves the shear capacity, cyclic stability, and seismic resistance of slender shear walls.

Abstract

Castella steel beams are among the most efficient solutions in steel construction; they can increase beam height, moment of inertia ( ), and section modulus ( ) without adding weight itself. Based on a previous study, sinusoidal openings have better structural performance than hexagonal openings due to their curved profile and minimal stress concentration. However, research on sinusoidal openings is still limited. This study uses the Finite Element Method (FEM) approach with ABAQUS software for a static load test. The numerical model was developed based on previous experimental studies and modified with variations in opening spacing of 100–300 mm (specimens A–E). The modeling was carried out on beams with spans of 2000 mm (short), 5000 mm (medium), and 10000 mm (long). The results of the study show that structural performance decreases as span length increases, with average load capacities of 140.14 kN, 116.99 kN, and 116.37 kN for short, medium, and long spans, respectively. Specimen D showed the highest ductility in all span variations. Based on the moment-curvature response and energy absorption, short-span beams performed the best, while long-span beams performed the worst. The span-to-beam height ratio recommendation is 0.56, because it has the best ductility performance.
