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 …

Finite Element Analysis and Validation of Axial Capacity of RC Columns Made of Steel Fiber Reinforced Concrete (SFRC)
Abstract: Steel Fiber Reinforced Concrete (SFRC) possesses many excellent dynamic performances such as; high resistance to explosion and penetration. It has little effect on pre-cracking behavior in uniaxial compression, but substantially enhances its post cracking response. This response leads to a greatly improved ductility and toughness. Steel fibers in SFRC are capable of preventing crack propagation as well as brittle failure of columns under uniaxial compression. To this end, four reinforced …

Esterification in Reactive Distillation Column Using Software Packages: A Review
Abstract: Abstract: Reactive distillation is the combination of reaction and separation in a same column. This represents an exciting alternative to traditional liquid phase chemical reaction processing. In reactive distillation, separation of products from unconverted reactants allows for better conversion, because produce elimination put out of place equilibrium and forces the reaction towards completion. The energy requirement of the conventional column is very and requires large recycling costs. Reactive Distillation is …
