CE 529 FRP Strengthening and Repair of Concrete Structures

3 Credit Hours

This course emphasizes the fundamental behavior of FRP strengthened/repaired reinforced concrete structures contributing towards sustainable and resilient civil infrastructure by extending the useful life of existing structures using advanced materials. As appropriate, reference is made to ACI440.2R: Guide for the Design and Construction of Externally Bonded FRP Systems for Strengthening Concrete Structures. The course material is applied to a practical strengthening design of a realistic reinforced concrete structure.

Prerequisite

Undergraduate reinforced concrete design (eg. CE327 or similar) and structural analysis (eg. CE325 or similar).

Course Objectives

Students will be able to analyze, design and/or assess rational strengthening or repair solutions for existing reinforced concrete structures using FRP materials based on sound fundamental principles. In addition, students will be able to effectively communicate strengthening analysis/design of a realistic reinforced concrete structure in a written report.

Course Topics

Topics will be selected from:

Overview of FRP material: basic material properties; manufacture of FRP products; durability considerations.

Flexural strengthening/repair of beams/slabs: fundamental interface bond-slip behavior; sectional analysis; debonding due to flexure and shear in RC beams/slabs; plate-end debonding; detailing considerations; retrofitting for serviceability; ductility.

Shear strengthening of beams: transverse FRP; debonding mechanism; interaction with internal steel stirrups.

Confinement of columns: FRP confined circular reinforced concrete columns; repair of seismically damaged columns.

Miscellaneous topics: case studies; FRP anchor design.

Textbook

No text book is required.

Class notes and other reference materials will be distributed as required.
