To develop an accurate design model that calculates the contribution of textile reinforced mortar (TRM) jackets to the total shear resistance of reinforced concrete beams based on governing failure modes.
Compiled and classified experimental literature data on TRM-strengthened concrete beams based on observed failure mechanisms.
Identified recurring failure modes, including fiber slippage through mortar, jacket debonding with concrete cover peel-off, and jacket tensile fracture.
Defined key mechanical and geometric parameters governing each failure mode to derive mode-specific analytical formulations.
Established analytical formulations to quantify TRM shear resistance contributions corresponding to each specific failure mode.
Defined a predictive criterion to identify the prevailing failure mechanism for a given TRM system, enabling selection of the appropriate design formulation.
