Behaviour and Analysis of Strain Hardening Fiber Reinforced Cementitious Composites Under Shear and Flexure

Significant effort has been vested over the years in quantifying the contribution of concrete to the shear strength of concrete members. By introduction of novel cementitious material, a much greater need to develop a standard to treat the concrete in a systematic manner is felt. In this thesis, an alternative framework of analysis to interpret the shear failure and the corresponding strength of the failure mechanism is suggested which gives an insight into a new interpretation of shear failure and relates to the state of bond of reinforcement over the entire span of a member. This approach is adaptable to be used for new concrete materials such as Strain Hardening Fiber Reinforced Cementitious Composites. An experimental program is also designed to provide a basis for the development of design rules which are prerequisite for the introduction of these novel materials in new construction. All experiments are conducted at York University.
