The Effects of Thermal Loading on Masonry Structures

Abstract:

Thin shell masonry structures are ideal for low-cost housing. Curved structures are ideally suited to resist external forces and are the most efficient structures. In shell structures, the forces are primarily in-plane, referred to as membrane forces. Shells, dominated by compressive stresses, are an absolute requirement in masonry structures, to minimize cracking. However, shell structures which are designed for pure compression still exhibit cracking on the external surface. Cracked shells are unsightly and a precursor to durability problems. For this reason, several studies have been undertaken to determine the cause of cracking in shells. This study is an investigation into the effects of thermal loading. The research includes the mapping of thermal loads by experimentation, an assessment of the effects of thermal loading and possible solutions to prevent cracking in the shell.
