The Structural Engineer, Volume 29, Issue 7, 1951
Gabled rigid frames are becoming increasingly common in single-storey factory construction, but where there are two or more bays the analysis by the usual methods of structural theory presents considerable difficulties in computation. This paper presents a method, based on the general conception of moment and thrust distribution, which greatly simplifies such problems. It is particularly advantageous where the structure consists of a large number of bays, where the roof members are in several straight portions or are curved, and where the members are of variable cross-section. It is also applicable to multi-span portal frame bridges. A.J. Francis
This month's letters include discussion over design checks and suitably experienced engineers as well as seismic design of masonry and more.
The tragedy of the Francis Scott Key Bridge highlights the need for structural engineers to ensure that the risks inherent in our built infrastructure remain acceptable, argues Colin Caprani.
