Introduction to Pull-out Test Analysis of a Hooked GFRP Bar Embedded in Timber with Epoxy Interface Background and Significance Fiber-reinforced polymer (FRP) bars, particularly glass-FRP (GFRP), are increasingly used as reinforcement in timber structures due to their high strength-to-weight ratio, corrosion resistance, and compatibility with wood. However, the bond behavior ...

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 the Concrete Cylinder Compression Test The concrete cylinder compression test is a standard method used to determine the compressive strength of hardened concrete, which is a key indicator of its quality and structural performance. This test is performed according to established standards such as ASTM C39 (American Society for Testing and Materials) or EN 12390-3 ...

Introduction to Simulation of Blast Resistance Behavior of Adhesively Bonded Cross-Laminated Timber-Concrete Composite (CLT-CC) Overview The simulation of blast resistance behavior in adhesively bonded cross-laminated timber-concrete composites (CLT-CC) represents an emerging area of research in structural engineering and blast mitigation. This composite system combines the advantages of cross-laminated timber (CLT) ...

Introduction to Blast Resistance Behavior of Interior Voided Slab-Column Connections Using Steel Sheets and CFRP Reinforcement Background and Significance Modern structures, particularly those in high-risk environments, require enhanced resistance to extreme loading conditions such as blast loads. Slab-column connections are critical zones in reinforced concrete (RC) frames, often susceptible to ...

Introduction to Flexural Testing of Timber Beams Reinforced with Steel Bars Overview The flexural test of timber beams reinforced with steel bars is an experimental procedure used to evaluate composite timber-steel structural elements’ bending strength, stiffness, and ductility. This test is essential for assessing how steel reinforcement enhances the mechanical ...

Introduction to Bullet Ballistic Impact on Hybrid Fiber-Reinforced Concrete (HFRC) Reinforced with CFRP Sheets Background Hybrid Fiber-Reinforced Concrete (HFRC) combines different types of fibers (e.g., steel, polypropylene, basalt, or glass) to enhance mechanical properties such as tensile strength, ductility, and impact resistance. When further reinforced with Carbon Fiber-Reinforced Polymer (CFRP) ...

Introduction to Modeling Steel Beam-to-CFDST Column Connection with Bolts Overview of CFDST Columns and Steel Beam Connections Concrete-Filled Double-Skin Steel Tubular (CFDST) columns consist of two concentric steel tubes with concrete sandwiched between them. These columns offer high strength, ductility, and excellent seismic performance. When connecting a steel beam to ...

Flexural Behavior of Adhesively Bonded Cross-Laminated Timber–Ultra-High-Performance Concrete (CLT-UHPC) Composite Panels Introduction Composite structural systems combining cross-laminated timber (CLT) and ultra-high-performance concrete (UHPC) have gained attention due to their potential to enhance structural efficiency, sustainability, and performance. CLT provides a high strength-to-weight ratio, carbon sequestration benefits, and ease of prefabrication, while UHPC contributes ...

Introduction to Low-Velocity Impact Behavior of Interior Voided Slab-Column Connections Using Steel Sheets Background Slab-column connections are critical structural elements in modern construction, particularly in flat-plate systems where shear resistance and punching strength are major concerns. Introducing voids within the slab (voided slabs) can reduce weight, improve material efficiency, and ...
