Blockwork Masonry Compressed in Two Orthogonal Directions
Publication: Journal of Structural Engineering
Volume 123, Issue 5
Abstract
An experimental investigation was conducted to study the difference in strength and behavior of unfilled and filled blocks and prisms compressed in two orthogonal directions, normal and parallel, to unit bed face. In some codes and standards no consideration has been given to the way the prisms should be constructed, nor to the way the blocks or prisms should be loaded to meet situations where the acting external forces are applied in a direction parallel to the unit bed face. This paper recommends methods of determining the specified compressive strength of blockwork masonry, , be used in the preceding and in strength design theory for masonry structures. The effects of using different grout mixes and mortar joint types on the samples' strength were also investigated. The results show that changing the mortar strengths have little influence on unfilled prisms strength compressed parallel to bed face compared to those compressed normal to bed face. The presence of grout significantly increased the filled prisms section capacity compared to unfilled prisms, but for the range of grout strengths used, the contribution of grout to the prisms section capacity was small.
