Michael Patrick Collins CM FRSC is a Canadian structural engineer [1] whose research is focused on the design and evaluation of reinforced and prestressed concrete buildings, bridges, nuclear containment structures and offshore oil platforms.
Collins received his BE from the University of Canterbury in New Zealand in 1964 and his PhD from the University of New South Wales in Australia in 1968. He joined the University of Toronto in 1969, was appointed to the Bahen-Tanenbaum Chair in Civil Engineering in 1995 and was selected as a University Professor in 1999. He is currently working on his Doctorate of Science [ citation needed ].
Collins has concentrated his research effort on understanding how cracked reinforced concrete resists shear stress. Shear failures can cause concrete structures to collapse without warning and hence, accurate analytical models for shear behaviour are critical for public safety. Unfortunately, most traditional shear design procedures rely upon empirical design rules which lack a rigorous theoretical basis and can be dangerous if applied to new situations. The Compression Field Theory, and subsequently the Modified Compression Field Theory, developed by Professor Collins and his colleagues at the University of Toronto, Division of Engineering Science, provides a rational basis for shear design and has received worldwide recognition. A Simplified Modified Compression Field Theory is currently the design standard in the Canadian CAN/CSA A23.3-04 which is the basic truss model, and soon to be updated and included in the European Building Code. [2] He is the author of over 80 technical papers, 8 of which have received a research prize.
In 2005, Collins was chosen as one of 10 provincial finalists in TVOntario’s first Best Lecturer competition. [3] [4] In 2011, Collins was elected as a Fellow of the Royal Society of Canada. [5]
John James Rickard Macleod,, was a Scottish biochemist and physiologist. He devoted his career to diverse topics in physiology and biochemistry, but was chiefly interested in carbohydrate metabolism. He is noted for his role in the discovery and isolation of insulin during his tenure as a lecturer at the University of Toronto, for which he and Frederick Banting received the 1923 Nobel prize in Physiology or Medicine. Awarding the prize to Macleod was controversial at the time, because according to Banting's version of events, Macleod's role in the discovery was negligible. It was not until decades after the events that an independent review acknowledged a far greater role than was attributed to him at first.
Reinforced concrete, also called ferroconcrete, is a composite material in which concrete's relatively low tensile strength and ductility are compensated for by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel bars (rebar) and is usually embedded passively in the concrete before the concrete sets. However, post-tensioning is also employed as a technique to reinforce the concrete. In terms of volume used annually, it is one of the most common engineering materials. In corrosion engineering terms, when designed correctly, the alkalinity of the concrete protects the steel rebar from corrosion.
The University of Toronto Scarborough, also known as U of T Scarborough or UTSC, is one of the three campuses that make up the tri-campus system of the University of Toronto. Located in the Scarborough district, Toronto, Ontario, Canada, the campus is set upon suburban parkland next to Highland Creek. It was established in 1964 as Scarborough College, a constituent college of the Faculty of Arts and Science. The college expanded following its designation as an autonomic division of the university in 1972 and gradually became an independent institution. It ranks last in enrolment size among the three University of Toronto campuses, the other two being the St. George campus in Downtown Toronto and the University of Toronto Mississauga.
Frank Martin Baron served as professor of civil engineering at the University of California, Berkeley and held an international reputation as an expert in the fields of bridge and roof-structure design, and seismic and wind analysis. He was twice the recipient of the prized Leon S. Moisseiff Award issued annually by the American Society of Civil Engineers (ASCE), and among his manifold professional affiliations, served as chairman of the US Council of the International Association for Bridge and Structural Engineering.
Zdeněk Pavel Bažant is McCormick School Professor and Walter P. Murphy Professor of Civil Engineering and Materials Science in the Department of Civil and Environmental Engineering at Northwestern University's Robert R. McCormick School of Engineering and Applied Science.

Anastasios (Tas) Venetsanopoulos was a professor of electrical and computer engineering at Toronto Metropolitan University in Toronto, Ontario and a professor emeritus with the Edward S. Rogers Department of Electrical and Computer Engineering at the University of Toronto. In October 2006, Venetsanopoulos joined what was then Ryerson University and served as the founding vice-president of research and innovation. His portfolio included oversight of the university's international activities, research ethics, Office of Research Services, and Office of Innovation and Commercialization. He retired from that position in 2010, but remained a distinguished advisor to the role. Tas Venetsanopoulos continued to actively supervise his research group at the University of Toronto, and was a highly sought-after consultant throughout his career.
A T-beam, used in construction, is a load-bearing structure of reinforced concrete, wood or metal, with a T-shaped cross section. The top of the T-shaped cross section serves as a flange or compression member in resisting compressive stresses. The web of the beam below the compression flange serves to resist shear stress. When used for highway bridges the beam incorporates reinforcing bars in the bottom of the beam to resist the tensile stresses which occur during bending.

Mete Avni Sözen was Kettelhut Distinguished Professor of Structural Engineering at Purdue University, Indiana, United States from 1992 to 2018.
The modified compression field theory (MCFT) is a general model for the load-deformation behaviour of two-dimensional cracked reinforced concrete subjected to shear. It models concrete considering concrete stresses in principal directions summed with reinforcing stresses assumed to be only axial. The concrete stress-strain behaviour was derived originally from Vecchio's tests and has since been confirmed with about 250 experiments performed on two large special purpose testing machines at the University of Toronto. Similar machines have been built in Japan and the United States, providing additional confirmation of the quality of the method's predictions.
Arching or compressive membrane action (CMA) in reinforced concrete slabs occurs as a result of the great difference between the tensile and compressive strength of concrete. Cracking of the concrete causes a migration of the neutral axis which is accompanied by in-plane expansion of the slab at its boundaries. If this natural tendency to expand is restrained, the development of arching action enhances the strength of the slab. The term arching action is normally used to describe the arching phenomenon in one-way spanning slabs and compressive membrane action is normally used to describe the arching phenomenon in two-way spanning slabs.
