At the Concrete Elegance event Bruce discussed the horizontal cantilever stair at the new Institution of Structural Engineers head-quarters.  He enjoyed presenting with Adam Knight from our collaborators Hugh Broughton Architects.

During the development of the design much effort went in to assessing the dynamic performance of the stair.  The best moment of the project was when we first walked the stair and knew that vibrations were indeed OK.  We then used smart phones to measure the vibrations as Expedition’s Pete jumped at strategic points … after post processing, the data recorded by the phones demonstrated that the behaviour very closely matches the design calculations.  Since then, Expedition has developed an app “Vibrate It” which will soon be available on the Google Play store for instant initial assessment of the dynamic performance of structures.
