Abstract |
In this study, the effects of the mortar plaster thickness on shear strength of a masonry infill wall were investigated. Specimens of the masonry wall were collected from existing school buildings and shear strength tests were conducted. The test results were compared with the masonry wall specifications of the ‘seismic performance evaluation and retrofit manual for school facilities (2019)’. In addition, finite element (FE) analysis was performed to analyze the shear strength variation with regard to the material conditions of the masonry walls and the mortar plaster. The experimental and analytical results indicated that the manual underestimates the shear strengths compared to the experimentally obtained values, which means that masonry wall strength can be significantly increased due to mortar plaster. Finally, FE analysis considering the mortar plaster provided results relatively similar to the experimentally obtained ones.
