Recommendations for Active-Learning Kriging Reliability Analysis of Bridge Structures
(American Society of Civil Engineers, 2025)Active-learning Kriging (AK) was developed as a surrogate-aided reliability technique to address the need for efficient reliability estimation when assessing complex limit states. The results of AK analyses are sensitive ... -
Bridge Maintenance Management Based on Routine Inspection Data: A Quantitative Approach
(American Society of Civil Engineers, 2025)Mainstream bridge management systems use Markov chains of bridge condition ratings (CRs) to simulate temporal bridge health degradations and apply Markov decision processes to find optimal repair schemes. However, CR-based ... -
Dynamic Effect of Bidirectional Crowd Behavior on Footbridges Considering Human–Structure Interaction
(American Society of Civil Engineers, 2025)This study employed an enhanced social force model to investigate the impact of bidirectional crowd load on the vertical vibration characteristics of pedestrian bridges. The research incorporated a two-step prejudgment ... -
Bespoke Footbridge for Studying Pedestrian–Structure Interaction with Vertical Vibration
(American Society of Civil Engineers, 2025)Progress in quantifying and codifying pedestrian–structure interaction with a vertical structural vibration and the effects on both human beings and structures has been slow, primarily owing to a lack of experimental ... -
Impact of Concrete Interfaces on the Mechanical Performance of 3D Printed Concrete Structures
(American Society of Civil Engineers, 2025)This study primarily aims to investigate the influence of concrete interface properties on the anisotropic behavior of three-dimensional (3D) printed concrete (3DPC). A numerical model employing the traction-separation law ... -
Predicting Buildability Using the Surface Texture of 3D Printed Concrete Elements
(American Society of Civil Engineers, 2025)The buildability of three-dimensional (3D) printable concrete is commonly measured by the number of layers that can be printed before a collapse or excessive deformations. Buildability depends on rheological properties and ... -
Finite-Element Modeling of Concrete-Filled Steel Tubular Columns under Axial Compression
(American Society of Civil Engineers, 2025)Concrete-filled steel tubular (CFST) structures involve pouring concrete into steel tubes, which exert a constraining role, significantly enhancing the ductility of the concrete. Such structures are gaining popularity in ... -
Orientation-Based Analysis of Trombe Walls with Enhanced Glazing Systems across Different Annual Thermal Periods
(American Society of Civil Engineers, 2025)Trombe walls (TWs) are among the principal energy-efficient passive alternatives for use in building envelopes. This study was carried out as a result of the dearth and limits of previous research on TW glazing units, as ... -
Daylighting Design Optimization of Complex Fenestration Systems with External Shading and Horizontal Slats in Tropical Elementary School Classrooms
