Furthermore, the adoption of low-cost materials, such as earth bricks (or tiles) enables relatively cheaper construction than that associated with ‘typical’ materials. However, earth masonry is very weak in tension and flexure; hence, there is a need to eliminate tension forces when designing these structures. In this paper the results of a series of experimental investigations, which focus primarily on wind loading are discussed. An important finding is that wind loading may govern the design of masonry catenary shells—particularly those with steep profiles. It is also presented that elements such as gable walls and window frames, which are often attached to these shells, have a tendency to cause cracking if they restrain thermal movement. Finally, shrinkage of mortar may lead to cracking if restraint is generated during construction.
