CORROSION AND STRUCTURAL BEHAVIOUR OF CORRODED REINFORCED CONCRETE COLUMNS

This book aims at introducing corrosion and earthquake engineering to master students in civil engineering and structural engineering  who do not have a particular background in this area.

The main objective of the book is to provide basic information for effects of corrosion on reinforced concrete members. This book has been completed from a research study on 30 corroded reinforced concrete columns. It also provides information for establishing on experimental test set up for corrosion studies for graduate students. 

Structural Engineers can use the developed models to predict the displacement ductility, yield and ultimate loads, energy dissipation capacities and viscous damping ratios of corroded RC columns as a function of corrosion levels. 

Organization of Chapters

Chapter 1 discusses the basic effects of corrosion on structural members.

Chapter 2 introduces the developed models on bond-slip relationships for corroded and uncorroded members

Chapter 3 presents a case study on cyclic loading of corroded reinforced concrete columns. This chapter includes, corrosion measurement techniques, Faraday Law, corrosion test setup, mechanical properties of corroded steel bars at different conditions, establishing a test setup for cyclic loading, FEMA 461 protocol for cyclic loading.

Chapter 4 introduces the measurement of actual corrosion levels from experimental studies, obtaining idealized load-displacement curves based on energy equilavence method, measurement of strain values from cyclic loading to be used in bond-slip and actual development length calculations.

Chapter 5 extends and summarize the previous models on corroded RC columns and presents the new models to be used for the prediction of the structural behaviour of corroded RC columns

Chapter 6 represents the rapid screening tool to predict the seismic performance levels of corroded RC columns based on recorded corrosion crack widths in situ.
