Pull-Out test analysis of a ribbed steel bar from the UHPC
1. Introduction The Pull-Out Test is a commonly used experimental method to evaluate the bond behavior between reinforcement (typically steel bars) and concrete. When using Ultra-High Performance Concrete (UHPC), a class of advanced cementitious composite materials with superior mechanical and durability properties, the bond characteristics can differ significantly from conventional concrete due to UHPC’s dense […]
Analysis of a reinforced concrete (RC) beam with an embedded spiral GFRP bar subjected to air blast loading
🔷 Introduction Reinforced concrete (RC) structures are widely used in both civilian and military infrastructure due to their strength, durability, and cost-effectiveness. However, under extreme loading conditions such as air blast loads—resulting from accidental or deliberate explosions—conventional RC beams may experience severe damage, including spalling, cracking, or even failure. To improve blast resistance, advanced composite […]
