Abstract
In this chapter, the author presents the basic principles and behavioral aspects of reinforced concrete (RC) strengthening with textile-reinforced mortar (TRM); the author also reviews a number of studies that have provided fundamental knowledge on the use of TRM as a strengthening and seismic retrofitting material of RC structures. In most cases, the effectiveness of TRM systems is quantified through comparison with equivalent fiber-reinforced polymer systems. The chapter covers: flexural strengthening of RC beams and two-way slabs; shear strengthening of RC beams with rectangular or T-sections using closed or three-sided jackets, respectively; confinement of axially loaded concrete subjected to concentric compression; seismic retrofitting of columns by improving plastic hinge behavior and seismic retrofitting of masonry infilled reinforced concrete frames. The author demonstrates that, in all cases, TRM jacketing offers a substantial increase in mechanical performance, which is quantified through strength and/or ductility calculations.
