چکیده

Abstract The paper shows the results of an experimental campaign aimed at investigating cyclic behavior a column-to-foundation joint for precast concrete elements. tested connection is realized adopting corrugated steel ducts embedded into foundation, in which column protruding rebars are anchored by grouting high performance mortar. program consists testing six full-scale reinforced square-section columns subject to quasi-static lateral load with constant axial compression. A preliminary series bond tests was carried out define some variables, i.e., longitudinal rebar diameter and anchorage length. Results joints compared those two reference cast-in-place specimens same geometric characteristics, showing similar hysteretic behavior, energy dissipation ductility values. Lastly, plastic hinge height computed all based on strains, current codes formulations.

Seismic Design Considerations for Precast Concrete Shear Wall Connections

The performance of precast shear wall panel structures subjected to earthquakes relies on the behaviour and integrity of the connections between the panels. The current lack of knowledge on the seismic behaviour of precast wall connections limits the use of such systems in earthquake areas. This paper presents results of an extensive experimental program undertaken at the University of Manitoba...

Seismic Behavior of Steel Reinforced Concrete Beam-Columns and Frames

The ability to perform accurate nonlinear simulations is a key component in the assessment of the behavior of seismic force resisting systems. A three-dimensional distributed plasticity formulation for composite beam-columns suitable for nonlinear static and dynamic analyses of composite seismic force resisting systems has been developed. New uniaxial constitutive relations are developed for th...
