Structural Upgrading Systems for Sustainable and Resilient Concrete Infrastructure

Abstract

Reinforced concrete is the most commonly-used construction material worldwide. However, the life span of typical concrete infrastructures is normally less than 100 years. Concrete structures may be damaged during their service life due to various attacks from wind, earthquake, waves, or fire, as well as different aggressive agents, such as chlorides and carbon dioxides. It will create very serious environmental problems if most of the deteriorated infrastructures need to be demolished. The aim of this Special Issue is to review the available structural upgrading systems for improving the resilience and prolonging the service life of infrastructure. Topics of interests for this Special Issue include, but are not limited to, the following: New approaches and technologies for enhancing the strength, stiffness, ductility and durability of concrete infrastructure, new theories and applications of seismic retrofitting systems, new systems for upgrading corroded reinforced concrete structures and repairing fire-damaged concrete buildings.
