Correspondence on The Elastic Buckling of Beams Under Mixed Gravity Loading by Professor B.K. Doughe

This paper describes the process by which Flyover House, 1960s office block, was changed into Vantage West, an office building satisfying current institutional requirements. A review of some of the more unusual features of the design is included. P.F. Winfield and S.J. Harvey

The line of thrust has been popular in describing the stability of masonry structures since Hooke first described it. Many methods of computation have been developed which allow the derivation of a line of thrust for a particular set of loads on a structure. Most of these are flawed in that they neglect the many aspects of the problem which are not defined. W.J. Harvey

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.
