A simplified design approach for predicting the flexural behavior of TRM-strengthened RC beams under cyclic loads

This paper proposes a simplified design approach to predict the flexural behavior of reinforced concrete (RC) beams strengthened by high-performance textile mortar (TRM) under cyclic loads. Based on experimental results, effect main factors as well effectiveness and reliability TRM strengthening layer loads were examined per ACI 437 method. The reinforcement ratio original RC beams, layer, interface bond between beam all have significant influence failure modes TRM-strengthened beams. models based fib model Architectural Institute Japan (AIJ) standard suggested capacity These also used evaluate curve while employing calculation deflection capacities results verified that presented good accuracy
