Book review: Equilibrium Finite Element Formulations

This month's letters discuss 3D printing and its future in construction, defining 'risk', British Standards versus Eurocodes, fire regulations in the wake of the Grenfell Tower tragedy, professional scrutiny on site, load factors, and the merits of the now-defunct Institution Yearbook.

Malcolm Turpin takes issue with the view that the structural engineering and construction sector is the ‘poor man’ of innovation, arguing that change is largely effected through an evolutionary approach of incremental steps.

This month's winner is Alasdair Massie of Peter Brett Associates, who receives an e-book of his choice from the Institution’s current catalogue. Alasdair's sketches reproduced here illustrate how part of a chimney might be removed and re-supported.
