Structural Safety and Reliability of Post-Tensioned Floor-Slabs
Gilbert Raynard, BASc, P.Eng., Struct.Eng., PE, SE | Principal

Post-tensioning with unbonded tendons offers great advantages for floor-slabs. Design and construction have to consider that a local damage accounts to the total loss of the tendon. The paper puts emphasis on the combination of prestressed and mild reinforcement and makes suggestions how to improve the reliability, ductility and redundancy of post-tensioned floor-slabs.

Sustainable Building Design Case history C.K. Choi Building, UBC
Gilbert Raynard, BASc, P.Eng., Struct.Eng., PE, SE | Principal

This paper describes the challenges and successes of the design of the C.K. Choi Building, for the University of British Columbia in Vancouver, Canada. The University wanted a building which would set new standards for sustainable design, construction and operation.

Modern infrastructure often incorporates very thick reinforced concrete members that are critical elements in the load-carrying system of the structure. Transfer slabs, footings, and mat foundations in high-rise construction are examples of such members. As building heights increase, demands on these members generally become greater, resulting in larger member depths.

Structural engineers always seek for smart materials and innovative strengthening techniques to effectively and efficiently address the escalating deterioration of structures. Recent assessment reports found that 50% of bridges in Canada are over 60 yeears old, and most of these bridges are classified as structurally deficient and/or functionally obsolete.

Recent catastrophic failures due to earthquakes revealed the vulnerability of our infrastructure as investigations conducted on these structures showed the main cause of failure was associated with the collapse of concrete columns leading to progressive failure of the structure

The present study investigated the dynamic behaviour of an irregular 32-storey reinforced concrete, Vancouver-style, high-rise, podium tower by assessing the influence of the floor diaphragm modelling stiffness assumptions on the structure’s modal properties.

Analysis of Field-Measured Reversible Deformations in Masonry Cavity Walls | DECEMBER 2015
Nick Trovato, BSc, MEng, P.Eng., FEC, FGC(Hon) | Managing Principal

Distress and failure of clay brick masonry facades is often believed to be the result of high compressive stresses arising from excessive vertical differential movement between the clay brick masonry facade and structural backing wall.
