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 ...

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 ...
