The pull-out behavior of steel fibers embedded in concrete is a fundamental mechanism governing the post-cracking performance, toughness, and ductility of fiber-reinforced concrete (FRC). When cracks initiate and propagate, the bridging action provided by steel fibers transfers stresses across crack faces, enhancing energy absorption capacity and residual strength. Therefore, understanding ...

The four-point bending test is a widely adopted experimental and numerical method for evaluating the flexural performance of reinforced concrete (RC) beams, particularly when investigating advanced cementitious materials such as Ultra-High-Performance Geopolymer Concrete (UHPGC). This test configuration is especially suitable for studying crack propagation, flexural strength, ductility, and load–deflection behavior ...

Masonry walls are among the most widely used structural elements in residential, commercial, and heritage construction worldwide. Composed of masonry units (brick, block, or stone) bonded with mortar, these walls exhibit complex mechanical behavior due to their heterogeneous and anisotropic nature. Understanding their structural response under different loading conditions is ...

Flat reinforced concrete slabs are widely used in building construction due to their architectural flexibility, reduced story height, and simplified formwork. However, their structural performance is often governed by punching shear failure at slab–column connections. This failure mode is brittle, occurs with little warning, and can lead to progressive collapse. ...

Concrete-filled steel tube (CFST) shear walls have been widely applied in high-rise and seismic-resistant structures due to their excellent load-bearing capacity, ductility, and energy dissipation performance. By combining the advantages of steel and concrete, CFST systems effectively delay local buckling of steel tubes while enhancing the compressive strength and confinement ...

Interlocking masonry constructed from rubberized concrete represents a sustainable alternative to traditional masonry systems, offering benefits such as reduced material waste, improved deformability, and enhanced energy absorption. The incorporation of recycled rubber into concrete alters its mechanical behavior, introducing nonlinear characteristics that influence the performance of interlocking block assemblies under ...

In this tutorial, the Simulation of an RC slab reinforced with CFRP rods and fiber concrete jacket with a mechanical anchorage member under impact load has been done. Over the past few decades, the challenges associated with ageing and deterioration have become prominent issues in the construction field. Reinforced concrete ...

In this tutorial, the Analysis of a Thin-walled C-section Steel Encased Concrete Composite column under compression load has been investigated. Thin-walled C-section steel encased concrete composite columns represent an innovative structural system that combines the advantages of both steel and concrete materials. These columns consist of cold-formed thin-walled steel C-sections ...

Introduction to Bolts as Shear Connectors in Concrete-Filled Steel Columns Overview In concrete-filled steel tube (CFST) columns, shear connectors are crucial for ensuring composite action between the steel tube and the enclosed concrete core. Bolts are increasingly used as shear connectors due to their ease of installation, adjustability, and effectiveness in transferring shear forces Role ...

Introduction to Flexural Behavior of Steel-Polypropylene Hybrid Fiber Reinforced Concrete Reinforced with GFRP Sheet The flexural behavior of steel-polypropylene hybrid fiber reinforced concrete (SP-HFRC) reinforced with glass fiber reinforced polymer (GFRP) sheets represents an advanced composite material system that combines multiple reinforcement mechanisms to improve the mechanical performance of concrete ...

Introduction to Numerical Study on CFRP-Lined Concrete Cylinder Pipe (CCP) Under Internal Explosion Concrete Cylinder Pipes (CCPs) are widely used in water transmission systems due to their high load-bearing capacity and durability. However, they are vulnerable to internal explosions caused by accidental gas ignition or deliberate attacks, leading to catastrophic ...

This tutorial investigates the Simulation behavior of a new type of reinforced concrete composite slab with a joint in Abaqus. The precast plank concrete and in-situ concrete topping are modeled as three-dimensional solid parts. The steel reinforcements are modeled as wire parts. You can see a figure of the assembled ...
