CFRP Tendons For The Repair Of Post-Tensioned, Ubonded Concrete Buildings
Amato, Lucio Roger (2009-04-23)The deterioration of prestressed concrete structures due to corrosion is a costly problem. This problem is accelerated in cold weather climates where de-icing salts are used. These salts accelerate the corrosion of the ... -
Cyclic Testing of Pre-engineered Beam-Hanger Connections & Reinforcement of Holes in Glulam Beams Using Self-tapping Screws
Vojtila, GabriellaThis thesis is split into two sections: the first evaluates the performance of pre-engineered beam-hanger connections under cyclic loading, and the second evaluates the reinforcement of holes in glulam beams using self-tapping ... -
Earthbag Housing: Structural Behaviour and Applicability in Developing Countries
Daigle, Bryce Callaghan (2008-09-12)Global awareness of environmental issues such as climate change and resource depletion has grown dramatically in recent years. As a result, there has been a surge of interest in developing alternative building techniques ... -
Evaluation of Polygonal Hollow Structural Steel Sections via Experimental and Finite Element Analyses
Kabanda, JohnThin-walled hollow sections such as rectangular hollow sections (RHS) have very high torsional rigidity, and thus make a very economic choice for applications which are susceptible to lateral torsional buckling. However, ... -
Evaluation of the Thermal and Structural Performance of Straw Bale Construction
Beaudry, KyleThis thesis is primarily divided into two distinct experimental programs evaluating: 1) the thermal performance and, 2) the structural performance of straw bale construction. The thermal performance chapter describes ... -
Fatigue Performance of a Hybrid CFRP/STEEL Splice Detail for Modular Bridge Expansion Joints
Arcovio, Stefano (2013-07-24)As traffic demand on bridges increases, loading cycles on critical components will increase, reducing their service life. Modular bridge expansion joints, which are imperative to allowing the bridge superstructure to move, ... -
Innovative Hybrid FRP/STEEL Splice Details for Modular Bridge Expansion Joints
Rameshni, Ramin (2011-12-01)Bridge expansion joints are directly subjected to traffic load, and thus prone to premature fatigue failure. Replacement of components such as modular bridge expansion joints is typically done in a staggered schedule to ... -
Interstorey Drift Performance of Timber Beam-Hanger Connections
Leach, HarrisonThis thesis is split into two distinct sections. The first describes the design of a testing setup for applying simulated earthquake loads to a timber beam-hanger connection, and the second evaluates the performance of ... -
Out-Of-Plane Bending Of Masonry Walls With Near-Surface-Mounted And Externally-Bonded Corrosion-Resistant Reinforcement
Mierzejewski, Wojciech (2010-05-31)Masonry walls subjected to out-of-plane loading, such as in a seismic event, require reinforcement to improve the ductility of the system. In current masonry construction practice, reinforcement is placed internally and ... -
Parallel-to-Grain Withdrawal Resistance of Structural Self-Tapping Screws in Canadian Timber
Gutknecht, ManoahThis thesis investigates the withdrawal capacity of self-tapping screws (STS) inserted parallel-to-grain. An experimental study was conducted with 100 screws tested in total. The experimental program includes two main test ... -
Post-Fire Assessment of Unbonded Post-Tensioned Concrete Slabs: Strand Deterioration and Prestress Loss
MacLean, Kevin J. N. (2007-12-21)Unbonded post-tensioned concrete slabs have been widely used in Canada and the United States since the 1960s, as they allow increased span-to-depth ratios and excellent control of deflections compared to non-prestressed ... -
Short- and Long-Term Performance of Compressed Earth Blocks and Sandwich Panels with Natural Skins
Mak, Kenneth (2014-11-05)A drastic increase in environmental awareness has increased demand for renewable materials, energy efficient design and low embodied energy. Two technologies that purport to address this demand are Compressed Earth Blocks ... -
Strengthening Slender S-Section Steel Columns Using CFRP Plates of Various Moduli
Ritchie, Allison (2014-07-02)This thesis investigates strengthening slender steel columns with carbon fibre reinforced polymer (CFRP) plates of various moduli. Three different types of CFRP were used in the study: Ultra-high modulus (430GPa), High ... -
Structural Behaviour of Plastered Straw Bale Assemblies Under Concentric and Eccentric Loading
Vardy, Stephen (2009-05-29)The use of plastered straw bale walls in residential construction is growing as builders and owners seek environmentally friendly alternatives to typical timber construction practices. Straw has excellent insulation ... -
Structural Behaviour of Plastered Straw Bale Panels Under Non-Uniform Loading
Rakowski, Michael Robert (2010-09-30)The search for more sustainable construction methods has created a renewed interest in straw bales technology. Straw bales are a composite material that is energy efficient and durable. Rectangular straw bales stacked in ... -
Structural Benefits of Hempcrete Infill in Timber Stud Walls
Mukherjee, Agnita (2012-01-31)Due to an increase in environmental consciousness in the construction industry there has been increasing interest in using natural building materials like rammed earth construction, straw bale construction and hempcrete ... -
Structural Testing of Compressed Earth Blocks and Straw Bale Panels
Tattersall, Graham (2013-10-30)Globally, there is a need for alternative building materials that require less energy to produce than conventional materials. These alternative materials have gained popularity in recent years, however there is a need to ... -
Transient High-Temperature Prestress Relaxation of Unbonded Prestressing Tendons for use in Concrete Slabs
Gales, John (2009-09-26)Unbonded post-tensioned (UPT) flat plate concrete slabs have seen widespread use in multi-storey office and condominium buildings since the 1960s. The popularity of these systems can be attributed to various economic and ...
