The concluding article in this series discusses the span-to-effective-depth method for verifying deflection limits of slabs and beams. (This article was corrected on 1 October 2015. For details, see the corrigendum published on page 37 of the October 2015 issue.)
This article is the first of two which will discuss the problem of corrosion of steel frames behind masonry elevations. It aims to provide an introduction to this form of construction and to consider the ways in which lack of maintenance can lead to corrosion of the steel frame, before setting out how remedial work should be approached.
The Timber Engineering Notebook series concludes by examining the use of glued-in rods for timber connections. The increased use of manufactured timber, such as glued laminated timber (glulam) and laminated veneer lumber (LVL), with improved mechanical properties and the ability to produce cross-sections of almost unlimited size,has driven the timber engineering industry to come up with improved connection systems. Glued-in rods and plates have been used in the UK as a method of connecting timber since the 1970s. They offer the possibility of creating concealed connections that are capable of transferring large forces and moments with minimal slip due to their high stiffness.
