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 ...

Study on Mechanical Performance of Prestressed UHPFRC U-Beam Bridges

Eugen Brühwiler

The forms of U-shaped UHPFRC beams have not been investigated for the highway footbridge. Compared with the traditional section forms, the U-shaped UHPFRC beams can reduce the material consumption under the condition of providing the same bearing capacity. ...

Experimental and Numerical Evaluation of Steel Columns for Performance-Based Seismic Assessment of Steel Moment Frames

Dimitrios Lignos, Alexander Riley Hartloper, Ahmed Mohamed Ahmed Elkady

This paper summarizes the findings of a long term experimental program corroborated with detailed finite element simulations that investigated the hysteretic behavior of wide-flange columns in steel moment-resisting frames (MRFs) designed in highly seismic ...

Comparison of Seismic Design Requirements for Steel Moment Resisting Frames with Emphasis on Stability of Columns in North America, New Zealand, and Europe

Ali Imanpour, Dimitrios Lignos

The seismic design provisions and stability requirements for steel columns used at the first storey of MRFs as specified is Canadian steel design standard (CSA S16), U.S. design provisions for steel buildings (AISC 341 and AISC 360), the New Zealand steel ...

Finite element simulation of buckling of extended beam-to-girder shear tab connections under gravity induced shear force

Dimitrios Lignos

Extended shear tab connections (either in full-depth or partial-depth configurations) have been widely used to connect simply supported beams to the web of supporting girders. Full-scale laboratory tests of extended beam-to-girder shear tab connections dem ...

Bonded sleeve connections for joining tubular GFRP beam to steel member: Numerical investigation with experimental validation

Yu Bai, Chao Wu, Zhujing Zhang

This paper investigates an innovative bonded sleeve connection for joining tubular GFRP and steel members. Experimental results focused on mechanical responses of beam-to-column specimens using bonded sleeve connections and conventional steel angle connect ...

Pre-buckling and post-buckling failure at web-flange junction of pultruded GFRP beams

Thomas Keller, Yu Bai, Chao Wu

Separation at the web-flange junction is a common failure mode of pultruded glass fiber-reinforced (GFRP) beams subjected to bending. The causes of this separation appear to depend on the presence of lateral supports to prevent lateral buckling. To clarify ...

Contribution to shear wrinkling of GFRP webs in cell-core sandwiches

Julia De Castro San Roman Fest, Thomas Keller, Behzad Dehghan Manshadi, Anastasios Vassilopoulos

Glass-fiber-reinforced polymer (GFRP) cell-core sandwiches are composed of outer GFRP face sheets, a foam core, and a grid of GFRP webs integrated into the core to reinforce the shear load capacity. One of the critical failure modes of cell-core sandwich s ...

Shear wrinkling of GFRP webs in cell-core sanwiches

Thomas Keller, Behzad Dehghan Manshadi, Anastasios Vassilopoulos

Glass fiber-reinforced (GFRP) cell-core sandwich structures are increasingly used in bridge deck and roof construction. GFRP cell-core sandwiches are composed of the outer GFRP face sheets, a foam core and a grid of GFRP webs integrated into the core in or ...

Zum Querkraftwiderstand von Stahl- und Spannbetonträgern mit dünnen Stegen

Eckart Hars

The design of reinforced and prestressed concrete girders is usually performed so as to avoid any non ductile failure mode. Amongst these failure modes, one of the most undesirable occurs by crushing of concrete in the web. To avoid this brittle type of fa ...
