Correspondence on The Longitudinal Bending Behaviour of Composite Box Girder Bridges Having Incomple

The parameters affecting the ultimate shear capacity of two-bay prototype beams have been examined using dimensional analysis; in particular, the importance of web slenderness and flange stiffness has been demonstrated. Design charts, which take into account the postbuckling behaviour of the web, have been proposed for beams having a clear web depth up to 600 mm. Values taken from the charts indicate that the current design procedure for beams with slender webs grossly underestimates their shear capacity. B.O. Hilson and P.D. Rodd

This month's letters cover legislation for design checks, embodied carbon of modular construction approaches, and assessment of masonry buildings for earthquake resilience in New Zealand.

This career-spanning book offers insight for anyone venturing into engineering, and how to build on the life lessons you learn along the way, writes Patrick Augustin.
