An Investigation of Concrete Masonry Wall and Concrete Slab Interaction

📖 The Scoop

Masonry building codes such as CSA Standard S304-1977[superscript 1] present simple and easy to use methods for the design of masonry bearing walls once the end moments and end loads on the wall are known. However, these codes do not present any method or guidelines to assist the designer in determining the wall end loadings that result from the interaction between a vertical masonry wall and a horizontal floor slab. The designer must use his engineering judgment and expertise in selecting the end moments and loads. The purpose of this study is to test various full-scale masonry wall-floor slab specimens in an attempt to better understand joint behavior and performance as it relates to moment resistance. Sixteen full-scale masonry wall-floor slab specimens were tested in the I.F. Morrison Structural Engineering Laboratory at the University of Alberta under the guidance and supervision of Dr. J. Warwaruk and Dr. J. Longworth. The variables investigated in this study included: 1. The level of axial load on the wall. 2. The amound of vertical reinforcement in the wall. 3. The mortar strength. 4. The degree of slab penetration into the wall cross-section. 5. The block size, i.e. wall thickness.
