CIV510H1 
Solid Mechanics II
This course provides a continuing study of the mechanics of deformable solids. Stress and equilibrium conditions, strain and compatibility conditions, stressstrain relations and yield/failure criteria are considered in the context of civil engineering materials. Twoand threedimensional elasticity theory is developed, with an introduction to the use of tensor notation. Advanced topics in bending, shear and torsion of beams are also covered, as is elementary plate bending theory. The course concludes with a further development and application of energy methods including virtual work, potential energy, strain energy, and related approaches.

Mechanics of Reinforced Concrete
Theories of elasticity and plasticity, as applied to reinforced concrete, are examined. Topics include: mechanical properties of concrete and reinforcement; constitutive relations; failure criteria; linearelastic models; nonlinearelastic models; elasticplastic models; limit analysis theorems; and an introduction to fracture mechanics of concrete. Compression field and smeared crack models are discussed, as are methods of their implementation and application in nonlinear finite element analyses. Prerequisites: CIV313H1, CIV510H1.

Research
Current Themes and Projects:
Further development of the software program VecTor4, a nonlinear finite element analysis program for reinforced concrete shell structures, focused on incorporating SC analysis capabilities is currently underway. The resulting analysis procedure will be used to perform a preliminary assessment regarding the behaviour of SC composite shell elements under seismic loading conditions, a research area not previously investigated. The capability of SC elements to achieve desirable ductility levels, specifically under threedimensional shear critical loading conditions, will be investigated.
In addition, work is being done to make the VecTor programs compatible with hybrid simulation tests. Hybrid simulation testing requires the use of a continuous feedback system between the physical model and the numerical model, often in realtime. Enabling the use of the VecTor programs as the numerical model will result in more accurate simulations of the complex nonlinear behaviour of concrete structural elements and, thus, more accurate hybrid simulations.
The VecTor programs, developed at the University of Toronto, are nonlinear finite element analysis programs for RC structures. These programs are capable of the analysis of shear critical structures accurately using less degrees of freedom than typically required by a hydrocode. This study focusses on improvement of VecTor programs to increase their capability and performance to handle missile impact analyses, where localized severe shear failure is observed.
For both materials the research is driven towards the behavior in shear under monotonic and cyclic loading. Our ability in effectively designing the structures above rides on the development of appropriate constitutive models for the characterization of the novel cracked composite. To more clearly isolate and study the shear behaviour, a series of panel specimens will be tested using the Panel Element Tester facility. The models to be developed will be implemented to facilitate use in the VecTor 2 Finite Element analysis program.
As part of the ICIMPACTS initiative, existing statistical distributions will be implemented into VecTor2 to randomize the program inputs and allow the user to conduct Monte Carlo simulations. Behaviour models for corroded reinforced concrete, the effect of corrosioninduced cracking, deterioration of bond strength, and variation in the area of steel will be researched and implemented into VecTor2 providing the ability to analyze corroded reinforced concrete. The ability to quantify the reliability of deteriorating infrastructure will provide engineers with the tools to assess the safety of such infrastructure and potentially predict and prevent events like the collapse of the reinforced concrete factory structure in Bangladesh in April 2013, or the Laval bridge collapse in September 2006. These tools will ultimate contribute to increased public safety in Canada and India.
However, it still represents an important durability issue that causes significant economic damage worldwide. Numerical simulation of AAR effects on concrete plays an important role in determining the behavior of AARaffected structures. As such, constitutive models for AARaffected concrete were implemented within the architecture of VecTor2. The AAR expansion was treated as a nonrecoverable offset strain using a computational procedure previously developed for elastic and plastic offset strains. Two distinct mechanisms were taken into consideration to fully capture the effects of AAR on concrete: material expansion and the accompanying changes in mechanical properties. Verification studies are being performed at two levels: materiallevel (cylinders, prisms, and cubes) and structurallevel (beams, shear walls) by modelling AARaffected specimens reported in the literature. The analytically determined responses currently show good agreement with the experimental results. The current accuracy will be improved once conclusions are drawn from the materiallevel investigation and the structural testing, parts of the study that is currently underway.
