Structural Behaviour Of Veneer Walls With Thin Layer Mortar

Summary

A brief overview of the possibilities of using thin layer mortar masonry for veneer walls is given, and a design method for such lintels is described.   During the last decade, in the Netherlands and Belgium, an increasing number  of veneer walls have been erected in clay brick and concrete  block masonry with thin layer mortar. Owing to the homogeneous appearance of such masonry, architects are especially fond of this new building technique.  Compared to  traditionally erected veneer walls, these walls have a higher stiffness and strength.  As a result, larger window openings can be spanned by thin layer mortar masonry without  additional supports such as concrete or steel lintels.  The real strength and stiffness of these "thin layer mortar masonry lintels" was evaluated.  For safety reasons, it is recommended that a light woven steel wire reinforcement be introduced into the thin layer mortar bed joints. The influence of different reinforcement ratios was evaluated analytically and experimentally with four-point bending  tests. Finally, design rules were developed.  5 refs.
