Torsional Behavior of Reinforced Brick Beams
Publication: Journal of Structural Engineering
Volume 116, Issue 6
Abstract
Laboratory tests of 21 reinforced brick masonry beams under pure torsion are described. Also, an ultimate torsional strength theory for brick masonry beams subjected to pure torsion is developed. The study described has been undertaken to obtain information about the behavior of reinforced brick masonry beams subjected to pure torsion. Beam specimens are rectangular in cross section and composed of two wythes of brick facings with a grout core reinforced with varying percentages of steel. Three types of brick are used with type S Portland cement lime mortar to provide different ranges of the ultimate compressive strength of masonry. Specimens are grouped into four series of tests in which the reinforcement patterns were different between each series. An ultimate strength theory is developed based on the failure mechanism using elastic bending theory and transformation of the cross section. Although comparison of the predicted ultimate strength theory of beams under pure torsion to actual beam test values show appreciable scatter, the results are predictable to an acceptable degree of confidence.
