Abstract:Based on the collected existing test data of shear performance and calculation formula of the shear strength of masonry wall strengthened by horizontal-paste and horizontal-vertical-paste fiber reinforce polymer laminate, factors considered in above calculation formula and distribution of test data were analyzed and sorted. According to the collected test data, the accuracy of shear bearing capacity formula was discussed and the calculation formula of efficiency coefficient of fiber reinforce polymer laminate was proposed based on the analysis of test data. By comparing the measured and calculated values of the shear capacity of masonry walls strengthened by horizontal-paste and horizontal-vertical-paste fiber reinforce polymer laminate, the applicability and accuracy of the formulas for calculating the shear capacity of reinforced concrete walls were verified. The results show that the accuracy of each formula is different, considering the influence factors such as axial compression ratio, wall aspect ratio, patch ratio and other factors, the calculation formula of efficiency coefficient of fiber reinforce polymer laminate can better reflect the utilization rate of fiber reinforce polymer laminate in reinforced masonry walls strengthened by horizontal-paste and horizontal-vertical-paste fiber reinforce polymer laminate. The calculation results of the shear strength of masonry walls reinforced with horizontal-vertical-paste fiber reinforce polymer laminate obtained by using efficiency coefficient of fiber reinforce polymer laminate are in good agreement with the experimental values.

Keywords:fiber reinforce polymer laminate; reinforcement; masonry wall; shear capacity
