Exploring the potential of the critical shear crack theory for reinforced and post-tensioned glass beams: Initial analysis and experiments

Alain Nussbaumer, Pieter Christian Louter, Jagoda Cupac

In the evolution of structural glass beam elements, the requirements for post-fracture load bearing capacity and safe failure behaviour have led to the development of reinforced and post-tensioned beams. Maximum bending capacity in the post-fracture state ...

Flexural behaviour of post-tensioned glass beams: Experimental and analytical study of three beam typologies

Alain Nussbaumer, Pieter Christian Louter, Jagoda Cupac

The concept of post-tensioned glass beams builds on the concrete analogy of the reinforced glass beams. By additionally prestressing the reinforcement in a post-tensioned system, a compressive pre-stress is applied on the glass, enhancing the initial fract ...

Life Cycle Analysis of Strengthening Existing RC Structures with R-PE-UHPFRC

Emmanuel Denarié, Amir Hajiesmaeili, Guillaume Habert

(PE)-UHPFRC, a novel strain hardening ultra high-performance fiber reinforced concrete (UHPFRC) with low clinker content, using Ultra-High MolecularWeight Polyethylene (UHMW-PE) fibers, was developed for structural applications of rehabilitation. A compreh ...

Stability Requirements of Deep Steel Wide-Flange Columns under Cyclic Loading

Dimitrios Lignos, Ahmed Mohamed Ahmed Elkady

Just recently, valuable experimental data that characterized the hysteretic behavior of deep wide-flange steel columns (i.e., column depth, d >16 inches) at full-scale became available. Such members are typically used in steel moment-resisting frames (MRFs ...

Post-tensioned glass beams

Jagoda Cupac

Over the last few decades, the application of glass in building construction has extended from small four-side supported windowpanes to areas traditionally reserved for other materials, such as roofs, floors, staircases and full building envelopes. Glass i ...

Effect of composite beam action on the hysteretic behavior of fully-restrained beam-to-column connections under cyclic loading

Dimitrios Lignos, Ahmed Mohamed Ahmed Elkady

This paper assesses the composite beam effects on the hysteretic behavior of fully-restrained beam-to-column connections as part of steel moment-resisting frames (MRFs) designed in highly seismic regions. A practical approach is developed based on availabl ...

Post-Tensioned Structural Glass Beams - Comparative Experimental Study

Pieter Christian Louter, Jagoda Cupac

This paper presents a study of a system of post-tensioned structural glass beams. In order to increase the initial fracture strength of glass beams and provide residual load-carrying capacity in the event of glass failure, annealed laminated glass beams ar ...

Performance limits of brick masonry spandrels

Katrin Beyer

Spandrel elements in unreinforced brick masonry buildings with timber floors consist of a masonry spandrel supported by either a timber lintel or a masonry arch. When subjected to seismic loading, the force-deformation relationship of such spandrel element ...

Post-tensioned girders with low amounts of shear reinforcement: Shear strength and influence of flanges

Aurelio Muttoni, Miguel Fernández Ruiz, Michael Markus Rupf

Assessing the strength of existing structures has become a major issue for structural engineers. Such analyses are often performed after changes of use of the structure or due to new design codes requirements. This is particularly relevant with respect to ...

Exploratory experimental investigations on post-tensioned structural glass beams

Pieter Christian Louter

This paper discusses two projects on post-tensioned glass beams, performed at EPFL and DTU, respectively. In these projects small scale glass beams (length of 1.5m and 1m) are post-tensioned by means of steel threaded rods tensioned at the beam ends. The p ...
