The Building Regulations Safe Span Tables for Timber Members

The Building Regulations for England and Wales, including the span tables for site-cut timber roofs for dwellings, have recently been revised and reissued. This paper demonstrates that the information given in, and with, the span tables is insufficient to form a safe roof of this type and goes on to propose alternative structural configurations. Finally, the paper argues that the span tables should be removed from the Building Regulations and that design of all timber roofs should be entrusted to structural engineers. J.B. Bellamy
