1. El-Sayed, Yasmine. Behaviour of GFRP prestressed concrete straps.

Degree: Civil Engineering, 2011, University of Manitoba

Steel straps are being used for confinement purposes of steel-free bridge deck slab. The objective of this study was to use GFRP prestressed concrete straps as an alternative to steel straps, and assess the effect of the alkaline concrete environment on the long-term performance of GFRP. Each strap was 160 x100 mm2 in cross section, 2000 mm in length and pre-tensioned with two 16 mm diameter GFRP strands. The experimental study included testing three sets of concrete straps, pre-stressed at 35%, 45%, and 55% of ultimate strength of GFRP. The straps were tested in tension after being subjected to temperatures from -25 °C to +40 °C in an environmental chamber. Another two sets of straps were cast and tested two and a half years later. The control and conditioned samples achieved comparable results proving that GFRP can withstand prestressing levels higher than 25% and up to 35% of their ultimate strength.

2. Lynch, Matthew Erin. Compressive and flexural performance of masonry strengthened with eco-friendly ductile cementitious composites (EDCC).

Degree: Civil Engineering, 2018, University of Manitoba

The behaviour of masonry prisms and beams strengthened with eco-friendly ductile cementitious composite (EDCC), which is a form of engineered cementitious composite (ECC), was investigated in this thesis. Compression and out-of-plane bending tests were performed to measure compressive resistance, modulus of elasticity, and flexural capacity. It was concluded that the compressive resistance of strengthened masonry prisms remained similar in load, while ultimate stress decreased due to the increased cross sectional area. In out-of-plane bending, the strengthened concrete masonry unit (CMU) beams showed a strength increase from 11 to 26 times and the strengthened brick showed an increase from 4 to 8 times versus the beams plain counterparts. The linear strength increase was dependent on EDCC thickness, although doubling the EDCC thickness did not double the strength. Overall, masonry strengthened with EDCC is a viable alternative to ECC strengthening due to the performance and reduction in cement content.

3. Murison, Evangeline Rivera. Anchored Log Decks.

Degree: Civil Engineering, 2014, University of Manitoba

To improve the performance of the conventional nail laminated bridge deck, three generations of innovative decks have been developed during the last three decades: (a) the stress laminated wood deck, (b) the stressed log bridge, and (c) the grout laminated wood deck. The grout laminated wood deck, the most recent wood deck, consists of trimmed logs interconnected with internal grout cylinders, in compression or tension. Previous research has shown that the grout cylinders have superior load distribution characteristics, but the cost of trimming the treated logs was found to be relatively high. Recently, research has been conducted to develop the next generation of the bridge wood decks, called the anchored log decks. The anchored log deck, meant for use as decking of steel girder bridges, consists of untrimmed discarded utility timber poles which have been treated with preservatives. The logs are held together by means of unstressed transverse proprietary Cintec anchors. The anchors consist of stainless steel rods encased in grout cylinders. Panels, each comprising of 5 to 6 logs, are preassembled to fit on a flatbed trailer for shipping. The smooth wearing surface over the log deck is provided by longitudinal sawn timber planks, with high-density foam filling the gap between the logs and the planks. The panels are inter-connected through inclined anchors passing through adjacent logs. At the University of Manitoba, an anchored log deck with five preassembled panels was constructed and tested to failure at several locations under both static and fatigue loads. The test results have shown that anchored log decks have the potential of being economical preassembled decks for steel girder bridges.
