Experimental investigation on the moment-rotation performance of pultruded FRP web-flange junctions

This paper aims to present an experimental investigation on the behavior of web-flange junctions (WFJs) rotational stiffness of pultruded fiber-reinforced polymer composites (FRP). Channels and I-sections were tested using a simple set-up, which was develo ...

Web buckling mechanism of pultruded GFRP bridge deck profiles subjected to concentrated load

Congzhe Wang, Yun Sun, Yuqing Liu

The web's local buckling is a major failure type of pultruded glass fiber-reinforced polymer (GFRP) bridge deck subjected to concentrated wheel loads. Three kinds of external actions-that is, in-plane shear force, local compressive force and bending moment ...

Shear-bending failure modeling of concrete ribbed slabs strengthened with UHPFRC

The use of Reinforced Ultra High Performance Fiber Reinforced Cementitious Composite (R-UHPFRC) materials in the strengthening of existing infrastructure has been more broadly exploited in recent years, although the main domain of application pertains to t ...

Long-term behaviour and ductility analysis of standard and fibre-reinforced concrete beams

Michele Albertini

Long-term concrete behaviour are two subjects of current interest in many studies published over the last decade. This thesis project is dedicated to the study of both the above mentioned topics, developing a comprehensive work that can further bring a hig ...

Hysteretic Behavior of Moment-Resisting Frames Considering Slab Restraint and Framing Action

Dimitrios Lignos, Ahmed Mohamed Ahmed Elkady, Hammad El Jisr

This paper examines the influence of framing action and slab continuity on the hysteretic behavior of composite steel moment-resisting frames (MRFs) by means of high-fidelity continuum finite-element (CFE) analyses of two-bay subsystems and typical crucifo ...

Application of Sustainable Bamboo-Based Composite Reinforcement in Structural-Concrete Beams: Design and Evaluation

Ian Smith

Reinforced concrete is the most widely used building material in history. However, alternative natural and synthetic materials are being investigated for reinforcing concrete structures, given the limited availability of steel in developing countries, the ...

Strengthening of steel beams using iron-based shape memory alloy (Fe-SMA) strips

Ardalan Hosseini, Masoud Motavalli, Elyas Ghafoori, Julien Michels

The current study presents a retrofit system, which can be used for strengthening of steel bridge beams using (un-bonded) mechanically-anchored iron-based shape memory alloy (Fe-SMA, ‘memory-steel’) strips. After anchoring, the Fe-SMA strips are activated ...

Composite steel beam database for seismic design and performance assessment of composite-steel moment-resisting frame systems

Dimitrios Lignos, Ahmed Mohamed Ahmed Elkady, Hammad El Jisr

This paper discusses the development of a publicly available database of composite steel beam-to-column connections under cyclic loading. The database is utilized to develop recommendations for the seismic design and nonlinear performance assessment of ste ...

Thermally activated iron-based shape memory alloy for strengthening metallic girders

Ardalan Hosseini, Masoud Motavalli, Elyas Ghafoori, Julien Michels

The study presents a new retrofit solution for strengthening metallic I-girders. The retrofit system involves two iron-based shape memory alloy (Fe-SMA, ‘memory-steel’) strips (each with a width and thickness of 50 and 1.5 mm, respectively) that are mechan ...

Flat prestressed unbonded retrofit system for strengthening of existing metallic I-Girders

Alain Nussbaumer, Ardalan Hosseini, Masoud Motavalli, Elyas Ghafoori

In this study, a novel retrofitting system is developed to strengthen existing metallic I-girders using prestressed unbonded carbon fiber reinforced polymer (CFRP) plates. The system relies on a pair of mechanical clamps. Each clamp holds two CFRP plates ( ...
