Seismic Analysis of a Steel Building Frame with Accordion Dampers
Introduction to Seismic Analysis of a Steel Building Frame with Accordion Dampers Seismic analysis is a critical part of structural engineering, aimed at evaluating how buildings respond to earthquake-induced forces. Steel building frames are widely used in seismic regions due to their ductility, high strength-to-weight ratio, and ease of construction. However, even these robust structures […]
Pull-out test analysis of a 3D ribbed steel bar from the UHPFRC
Abstract In this tutorial, the Simulation pull-out test of a ribbed steel bar from Ultra-High-Performance-Fiber-Reinforced Concrete in Abaqus has been investigated. The steel bar is a three-dimensional model with full details. The UHPFRC part is modeled as a three-dimensional solid part. To model UHPFRC, the Concrete Damaged Plasticity material behavior with strain damage option is […]
Analysis of an ice sheet in interaction with water subjected to underwater explosion load
In this tutorial, the simulation of an ice sheet in interaction with water subjected to underwater explosion(UNDEX) load by using the CEL method has been studied. To model ice failure and damage, the Johnson-Holmquist brittle damage model is considered. In polar and subpolar regions, floating ice sheets often interact with man-made structures and activities, including […]
Analysis of the bolted wood-steel panel under tension load
Analysis of Bolted Wood-Steel Panels under Tension Load In modern timber construction, hybrid systems that combine wood and steel elements are increasingly used to optimize structural performance and material efficiency. One such hybrid system is the bolted wood-steel panel, where steel plates are bolted to timber elements to transfer loads, improve stiffness, and enhance connection […]
Simulation and analysis of subsurface tunnel with GFRP protection against internal blast using CEL method
Introduction In recent years, the threat of internal explosions within critical underground infrastructure, such as transportation tunnels, utility corridors, and military bunkers, has underscored the need for advanced protective measures. Subsurface tunnels, though naturally shielded from surface threats, are particularly vulnerable to internal blasts due to their enclosed geometry and confined environment. The resulting overpressure […]
Analysis of shock pressure and shock-wave attenuation near a blast hole in rock with CEL method
Introduction Blasting is a widely employed technique in mining, tunneling, and civil engineering to fragment rock masses for excavation and material handling. When an explosive charge is detonated within a blast hole, it generates an intense shock wave that propagates through the surrounding rock medium. The initial shock pressure is extremely high near the borehole, […]
Axial compression test of a composite panel made of profiled steel skin and concrete core
Introduction Composite panels comprising profiled steel skins and a concrete core have gained increasing attention in modern structural engineering due to their high strength-to-weight ratio, rapid assembly, and favorable mechanical properties. These sandwich-type panels, often referred to as steel-concrete composite panels (SCCPs), are commonly used in applications such as modular construction, prefabricated buildings, and protective […]
Analysis of interior voided slab-column connections using steel sheets under low-velocity impact
Introduction Flat slab systems are increasingly utilized in contemporary construction due to their architectural flexibility, reduced formwork complexity, and efficient space utilization. However, the absence of deep beams and drop panels renders slab-column connections particularly susceptible to punching shear failures. This vulnerability is further exacerbated when the structure is subjected to dynamic actions such as […]
Analysis of reinforcement of timber beam with steel bars and epoxy glue
Introduction Timber has been a traditional construction material for centuries due to its availability, ease of use, and aesthetic appeal. However, its inherent limitations in tensile strength, stiffness, and long-term durability under varying environmental conditions have led to the exploration of reinforcement techniques to enhance its structural performance. Among these, the use of steel bars […]
Strengthening of reinforced concrete slabs using carbon fiber reinforced polymers rods and concrete jacket with a mechanical anchorage system under rigid impact load
Abstract This study presents the development of a new method for strengthening Reinforced Concrete (RC) slabs using Carbon Fiber Reinforced Polymer (CFRP) rods and an Ultra-High Performance Fiber Reinforced Concrete (UHPFRC) external jacket with a Mechanical Anchorage System (MAS) under impact loading. Introduction Over the past few decades, the challenges associated with ageing and deterioration […]
