Prestressed Steel Structures Discussion on Professor Magnel’s Paper

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 additional references for the June issue's Regent Street disease article and discussions about seismic design and minimum qualifications for carrying out structural engineering services.

This book is a must-read for engineering leaders, offering a fresh perspective and practical guidance on embedding diversity, equity and inclusion into the profession, writes Mariska van der Velden.
