Strengthening of Existing Concrete Structures: Options, Design, and Installation Case Studies

Restoration and renovation projects often include the need to increase the capacity of existing structural members to accommodate increased design loads or address deficiencies in the original design or construction. This presentation will provide an overview of various options to increase the shear and flexural capacity of existing reinforced concrete members. The presentation will discuss current design procedures, review installation factors that impact the feasibility and selection of the various strengthening options, and discuss project case studies utilizing the various options.

By the end of this webinar, participants will be able to:
– Understand the available options for strengthening existing concrete structures.
– Describe the current design procedures for FRP and supplemental steel reinforcement.
– Understand the limitations of specific reinforcement options with regards to strengthening limits, including fire considerations.
– Describe the installation factors that may impact the feasibility or performance of the various strengthening options.
