Behavior of Slender GFRP Reinforced Concrete Columns

Khorramian, Koosha; Sadeghian, Pedram (American Society of Civil Engineers, 2019-04-24)

This paper presents an experimental and analytical study on slender concrete columns reinforced with glass fiber-reinforced polymer (GFRP) bars. The experimental program included ten concrete columns with rectangular ...

Benchmarking numerical freeze/thaw models

Ruhaak, Wolfram; Anbergen, Hauke; Grenier, Christophe; McKenzie, Jeffrey; Kurylyk, Barret; Molson, John; Roux, Nicolas; Sass, Ingo (Elsevier, 2015-08-28)

Bond-Slip Analytical Formulation toward Optimal Embedment of Concrete-Filled Circular FRP Tubes into Concrete Footings

Sadeghian, Pedram; Fam, Amir (American Society of Civil Engineers, 2010-03-15)

This paper presents a robust analytical model for a moment connection of concrete-filled fiber reinforced-polymer (FRP) tubes (CFFTs) to concrete footings. The CFFT connection is based on a simple approach of direct embedment ...

Calibration of Reduction Factor for Concrete Columns Strengthened with Unidirectional Fiber-Reinforced Wrapping

Khorramian, Koosha; Oudah, Fadi; Sadeghian, Pedram (2019-06-04)

Strengthening with fiber-reinforced polymer (FRP) wrapping is a well-established method of retorifiting or upgrading existing concrete columns. The available test data cooreponding to FRP wrapped concrete columns has ...

Characterization of Combined Longitudinal and Transverse FRPs for Strengthening Concrete Columns

Sadeghian, Pedram; Fillmore, Brandon (NRC Research Press, 2019-09-04)

This paper presents the results of a study on the characterization of combined longitudinal near-surface-mounted (NSM) fiber-reinforced polymer (FRP) bars and transverse FRP wraps for strengthening concrete columns. A total ...

Characterizing Porosity and Diffusive Properties of Monolithic Cement-Based Solidified/Stabilized Materials

Goreham, V.; Lake, C. B.; Yuet, P. K. (2012-07)

This paper presents the application of a single reservoir diffusion test to determine both the effective porosity of a soil-cement matrix and the diffusivity of tritium through saturated, monolithic, cement solidified/stabilized ...

Climate change impacts on groundwater and soil temperatures in cold and temperate regions: Implications, mathematical theory, and emerging simulation tools

Kurylyk, Barret L.; MacQuarrie, Kerry T. B.; McKenzie, Jeffrey M. (Elsevier, 2014-11-15)

Climate change impacts on the temperature and magnitude of groundwater discharge from shallow, unconfined aquifers

Kurylyk, Barret L.; MacQuarrie, Kerry T. B.; Voss, Clifford I. (Wiley (AGU publications), 2014-05-15)

Closed-Form Model and Parametric Study on Connection of Concrete-Filled FRP Tubes to Concrete Footings by Direct Embedment

Sadeghian, Pedram; Fam, Amir (American Society of Civil Engineers, 2010-10-30)

Concrete-filled fiber reinforced polymer (FRP) tubes (CFFTs) have been introduced as a new system for piles, columns and poles. A simple moment connection based on direct embedment of the CFFT into concrete footings or ...

Competition model for aperiodic stochastic resonance in a Fitzhugh-Nagumo model of cardiac sensory neurons

Kember, G. C.; Fenton, G. A.; Armour, J. A.; Kalyaniwalla, N. (American Institute of Physics Inc, 2001)

A model is presented to access the cause and effect between noisy threshold inputs and the average firing rate generated by neuron. The neural control in the heart in aperiodic stochastic resonance (ASR) was partially ...

Compressive Behaviour of Concrete Cylinders Reinforced with Glass Fiber Reinforced Polymer Bars

Fillmore, Brandon; Sadeghian, Pedram (Canadian Society for Civil Engineering:, 2017-05-31)

Current design standards ignore any contribution of glass fiber reinforced polymer (GFRP) bars in concrete in a state of compression. This paper challenged this convention by testing 30 cylinders of 36 MPa concrete to ...

Consensus formation control for a class of networked multiple mobile robot systems

Sheng, Long; Pan, Ya-Jun; Gong, Xiang (Hindawi Publishing Corporation, 2012)

Contribution of Longitudinal GFRP Bars in Concrete Cylinders under Axial Compression

Fillmore, Brandon; Sadeghian, Pedram (NRC Research Press, 2018-01-15)

Contribution of longitudinal glass fiber-reinforced polymer (GFRP) bars in concrete columns under compression has been ignored by current design guidelines. This paper challenges this convention by testing 21 concrete ...

Control of cardiac function and noise from a decaying power spectrum

Kember, G. C.; Armour, J. A.; Fenton, G. A.; Malhotra, A. (American Physical Society, 2004)

The transduction capability of cardiac affected neurons situated to the heart to control cardiac function was described. It was observed that the through in situ cardiac afferent activity shows evidence of independent and ...
