Cyclic Shear Resistance of Expanded Beam-Column Joint

Numerical Analysis of Cyclic Behavior of Beam-To-Column Bolted Connections in Steel Frames

This article considers the seismic behavior of beam-to-column joints in steel frames for different bolt arrangements by using of finite element modeling. As the most important beam-to-column joint type, the beam-to-column joints with end-plate is chosen for the analysis. Four different specimens have been analyzed. These models had some differences such as bolt arrangement and the presence or a...

Retrofitting of Beam-Column Joint Using CFRP and Steel Plate

─This paper presents the retrofitting of beam-column joint using CFRP (Carbon Fiber Reinforced Polymer) and steel plate. This specimen was tested until failure up to 1.0% drift. This joint suffered severe damages and diagonal cracks at upper crack at upper column before retrofitted. CFRP were wrapped at corbel, bottom and top of the column. Steel plates with bonding were attached to the two bea...

Numerical Simulation with Fibre Beam-column Models of Thin Rc Column Behaviour under Cyclic Tension-compression

Damage to structural walls in the recent earthquakes in Chile (2010) and New Zealand (2011) demonstrated that modern reinforced concrete (RC) wall behaviour can be largely governed by out-of-plane displacements triggered by instability. Thin walls are the most vulnerable to this deformation mechanism, especially if they have a single layer of reinforcement. These wall types can be easily found ...

Cyclic Evolution of Damage and Beam-column Interaction Strength of Concrete-filled Steel Tube Beam-columns

The assessment of response of composite seismic force resisting systems requires accurate nonlinear formulations for the composite members. In this work, reporting the first phase of a NEES project, a three-dimensional distributed plasticity formulation is presented for both circular and rectangular composite concrete-filled steel tubes (CFTs) that includes new constitutive models for the concr...
