- Description
- Over recent years there has been a trend toward the use of hit-and-miss masonry (also known as lattice masonry, see-through masonry, perforated masonry, and masonry screens) by architects in Australia. Hit-and-miss masonry is a unique brickwork technique in which mortar perpend or head joints are left unfilled by leaving gaps between adjacent masonry units along the courses. The openings provide ventilation by allowing the passage of light and air through the wall and also create an interesting texture of the building when dividing space both externally and internally. In Australia, hit-and-miss masonry is widely used for non-loadbearing walls, however, it is still some subject to some force (if it is situated outside the perimeter of a building) as a result of wind or earthquake loads that are may be applied to the wall. Structural engineers have the challenge of designing this special form of masonry due to the lack of global design guidance. To aid in the design of hit-and-miss masonry, the Centre for Infrastructure Performance and Reliability at The University of Newcastle, Australia has constructed and tested 21 single leaf hit-and-miss masonry walls using extruded clay bricks (230 mm long x 110 mm wide x 76 mm high) and 1:1:6 (cement: lime: sand) mortar. Those walls were tested in one way horizontal bending, one way vertical bending and two way bending. This paper presents three dimensional (3D) finite element (FE) modelling of the out-of-plane behavior of the hit-and-miss masonry for one way vertical bending only. The results obtained from the FE analyses were compared to the experimental results and Australian standards. A relationship between the out-of-plane capacity and bedded area of the mortar is also established and compared to current Australian standards.
