- Abstract
Background: Masonry infrastructure has been found to be deficient in resisting out-of-plane loads, such as vehicular collisions, rockfalls, and debris impact. Therefore, the manuscript is focused on studying the behaviour of clay and concrete brick masonry walls against low velocity out of plane impact loading. The influence of varying aspect ratio and boundary conditions were studied in detail for both clay and concrete brick walls. Methodology: The impact tests were conducted using a pendulum drop weight impact testing machine. Four different types of wall configuration were tested in order to check the influence of boundary conditions and aspect ratio. The aspect ratio of the clay brick wall designated as CW1, CW3 and CW4, whereas the concrete brick wall designed as CoW1, CoW3 and CoW4 was varied as 1, 2 and 4.8, respectively. The effect of boundary conditions was studied with respect to the parallel and perpendicular to the bed joint of clay brick masonry walls are designed as CW1 and CW2, respectively. Similarly, the boundary conditions were studied on concrete brick masonry walls designed as CoW1 and CoW2, respectively. Objective: The study focused to understand the impact response of masonry walls with concrete bricks that incorporate crumb rubber and fibers and compared with clay brick walls. The effect of boundary conditions was studied with respect to the parallel and perpendicular to the bed joint of masonry walls in terms of force-time history, failure mechanism and energy absorption. The influence of aspect ratio on the response of masonry walls are also studied in detail. Conclusion: It was concluded that the resistance offered by concrete brick walls was more as compared to the clay brick wall, however, the difference become insignifiacnt when aspect ratio is increased. The orientation of bed joint affects the energy absorption characteristics of walls as energy absorption was more when bed joint was in perpendicular to boundary conditions as compared to parallel orientation for both clay and concrete brick walls.
