Foundation of Building
Abstract: Recent trends in civil engineering underscore the importance of designing foundations that can withstand varying load conditions and environmental challenges. Selecting the appropriate foundation depth is critical for stability, particularly under intense loads. In regions with high rainfall, understanding maximum precipitation levels and water infiltration is vital. Water penetration into the soil can significantly reduce its load-bearing capacity, with saturation potentially lowering it by up to 50%. Foundations must also …

Structural Behavior of Flexible and Semi-Rigid Beam-Column Joint Connections by FEM
Abstract: This study investigates the structural behavior of flexible and semi-rigid beam-column joint connections in cold-formed steel (CFS) structures, focusing on the use of Finite Element Modeling (FEM) to simulate their performance under various loading conditions. Traditional analysis methods often oversimplify beam-column connections, treating them as either perfectly rigid or fully flexible, which does not accurately capture real-world joint behavior. In reality, many beam-column joints exhibit semi-rigid characteristics, where the stiffness …
