Analysis of the aluminum multi-particle impact in the cold spraying process

Introduction Cold spraying is an advanced coating technique that involves the acceleration of solid powder particles—typically metals like aluminum—to supersonic velocities using a high-pressure gas stream, usually at relatively low temperatures (below the melting point of the material). These particles impact a substrate and bond with it through plastic deformation rather than melting and solidifying, […]
Analysis of the UHPC beam-column joint reinforced with steel angle and bolts

Introduction Beam-column joints are critical components in reinforced concrete (RC) frame structures, especially in seismic regions where they are subjected to complex loading conditions such as bending, shear, and torsion. The integrity and ductility of these joints significantly influence the overall seismic performance and structural resilience of buildings. Conventional concrete often struggles to meet the […]
Analysis of ceramic plates as shielding for the UHPC panel against projectile penetration

Introduction In modern protective structures, the threat posed by high-velocity projectiles—whether from military weaponry or industrial accidents—has necessitated the development of advanced armor systems. Among these, Ultra-High-Performance Concrete (UHPC) has emerged as a promising material due to its exceptional compressive strength, ductility, and energy-absorbing capabilities. However, UHPC alone may not provide sufficient resistance against high-speed […]
Bending test analysis of the steel-concrete composite beam in the SRC structure

1. Introduction Steel-Reinforced-Concrete (SRC) structures are hybrid structural systems that combine the compressive strength of concrete with the tensile and ductile capabilities of embedded steel elements. A key component of SRC systems is the steel-concrete composite beam, which integrates structural steel sections (I-beams or H-sections) and reinforced concrete into a unified structural member. The bending […]
Analysis of aluminum-wood composite panels under high-velocity impact

Introduction Aluminum-wood composite panels are hybrid materials that combine the high strength and lightweight characteristics of aluminum with the natural energy absorption and aesthetic qualities of wood. These materials are increasingly used in sectors such as construction, transportation, and protective structures where both structural performance and impact resistance are critical. One area of growing interest […]
Fire and bending analysis of hollow-core concrete slab-DCT method

1. Introduction Hollow-core concrete slabs (also called precast prestressed hollow-core slabs) are widely used in building construction for floor and roof systems due to their high structural efficiency, cost-effectiveness, and speed of installation. These slabs are characterized by continuous voids (or cores) running through their length, reducing self-weight while maintaining strength. However, their behavior under […]
Analysis of the Seismic Behavior of Semirigid Steel Frame with X-Shaped Brace

Introduction Steel frame structures are widely used in modern construction due to their high strength, ductility, and adaptability to various architectural designs. Traditionally, these frames are modeled as either rigid or pinned; however, real-world behavior often falls between these extremes, hence the term “semirigid connections.” These semirigid joints exhibit partial moment resistance and rotational flexibility, which significantly […]
Cyclic Loading Analysis of an Open-Leg Steel Beam-Column Joints

Introduction to Cyclic Loading Analysis of an Open-Leg Steel Column Cyclic loading analysis refers to the study of a structure’s behavior when subjected to repeated or fluctuating loads over time. This kind of analysis is particularly important for steel structures, which may experience dynamic or seismic events, wind loads, vehicle vibrations, or machinery-induced forces. One […]
Cyclic loading analysis of a steel beam-column joint with a welded steel angle

Introduction to Cyclic Loading Analysis of Steel Beam-Column Joints with Welded Steel Angles In structural engineering, beam-column joints play a critical role in transferring forces and ensuring stability within steel frame structures. When subjected to cyclic loading, such as those experienced during earthquakes or wind loads, these joints must withstand repeated stress reversals without significant […]
Numerical analysis of the CFRP blanket effect on reducing the deformation of pipelines in soil exposed to the Coupled Eulerian-Lagrangian subsurface explosion

Introduction Pipelines are critical infrastructures for the transportation of oil, gas, and other essential resources. Among these, API 5L X65 grade steel pipelines are commonly used due to their strength and cost-efficiency. However, pipelines buried in soil are vulnerable to extreme events such as subsurface explosions, which may result from accidental or intentional detonations. These […]
