Characterization of Fresh and Hardened Properties of 3D Printable Cementitious Materials Produced with Ground-Granulated Blast-Furnace Slag
(University of Waterloo, 2021-09-24)Application of additive manufacturing technology to promote the digital construction practice in civil engineering has been gaining momentum, especially during the past 5 years. To this end, three dimensionalconcrete ... -
Correlation of Tensile Strength to Flexural Rupture Modulus of GFRP Bars
(University of Waterloo, 2021-05-04)Glass fibre reinforcing polymer (GFRP) bars are becoming a more comparable alternative to steel rebar used as tensile reinforcement for concrete, due to their cost effectiveness compared to other alternatives. GFRP has ... -
Effect of Unbalanced Moment on Punching Shear Strength of Slab-Column Joints
(University of Waterloo, 2020-05-27)The design of reinforced concrete flat plate slab-column connections subjected to unbalanced moments varies greatly between national design codes. Specific to Canada and the United States (U.S.), assumptions relating to ... -
The effects of curing- and service- conditions on durability of reinforced concrete structures
(University of Waterloo, 2020-06-01)Reinforced structural concrete is a critical building block of our civil infrastructure, especially our roads and bridges. As the transportation network grows, and our current infrastructure continues to age, the social ... -
Experimental Investigation of the Shear Behaviour of Slender Concrete Beams Reinforced with GFRP
(University of Waterloo, 2019-09-19)Glass fibre-reinforced polymers (GFRP) are being used as longitudinal and shear reinforcement in specialized concrete applications. GFRP products are designed as direct replacements for conventional steel reinforcement and ... -
Finite Element Modelling of FRP Reinforced Concrete Beams and Comparative Analysis of Current Strength Prediction Methods
(University of Waterloo, 2017-05-23)The modelling of glass fibre reinforced polymer (GFRP) reinforced, concrete beams was conducted by the author in the finite element analysis software ABAQUS. The study extended upon the work done by Joseph Stoner (2015) ... -
Large Scale Testing and Modelling of Reinforced Concrete Flat Plate Systems in Seismic Areas
(University of Waterloo, 2015-11-12)The focus of this research is on developing new punching shear retrofit techniques for slab-column connections to improve the seismic response of flat-plate systems. Previous tests have shown the effectiveness of using ... -
A NEW PUNCHING SHEAR STRENGTHENING TECHNIQUE FOR REINFORCED CONCRETE SLABS AT INTERIOR SLAB-COLUMN CONNECTIONS
(University of Waterloo, 2016-10-27)In certain situations the punching strength of a connection may become inadequate after construction due to changes of connection geometry from drilling or coring, or from changes of building use, or construction and ... -
Nonlinear Finite Element Analysis of Influence of Support Geometry on the Punching Shear Behaviour of Reinforced Concrete Slabs
(University of Waterloo, 2023-06-23)Due to their many benefits including ease of construction, open floor plans and reduced cost reinforced concrete flat slabs are one of the most common structural systems. However, these systems, particularly flat slabs ... -
Nonlinear Finite Element Analysis of Punching Shear of Reinforced Concrete Slab-Column Connections
(University of Waterloo, 2016-01-08)The code provisions for the design of reinforced concrete slabs are based on empirical and mostly statistical formulations derived from the tests. The available testing database consists of different types of slabs and in ... -
Nonlinear Finite Element Analysis of Punching Shear of Reinforced Concrete Slabs Supported on Rectangular Columns
(University of Waterloo, 2018-08-22)Historical and current design code provisions for the punching shear of reinforced concrete slabs supported on rectangular columns vary greatly and are primarily based on empirical results. Additionally, the existing ... -
Nonlinear Finite Element Analysis of Reinforced Concrete Slab-Column Connections with Headed Stud/Bolt Shear Reinforcement Subjected to Punching Shear
(University of Waterloo, 2022-08-29)While many experimental tests have been conducted by various researchers on the punching behaviour of reinforced concrete flat slabs supported on columns with headed stud/bolt shear reinforcement, there are still many ... -
