The Structural Engineer, Volume 76, Issue 9, 1998
Today’s enlightened businesses are already claiming to be customer focused. But what does this mean? - at best, higher levels of customer service and, at worst, higher training costs in customer care with no lasting payback. Being customer focused means understanding your customer’s aims and objectives and developing products and services to help achieve them; but it also means understanding the factors and nuances of the sectors which your customer is targeting. J.R. Johnson
A radical investigation of concrete frame design and construction is being carried out at BRE ’S Large-Building Test Facility at Cardington where once airships were built and the late Sir Alfred Pugsley learnt the value of structural testing on aeronautical frames. This assessment of BRE’s in situ concrete project, the first of four planned with Government support and the help of the concrete industry, has been compiled for The Structural Engineer by John D. Allen.
The shear capacity of headed studs in precast concrete hollow-core slab construction has been determined experimentally in 12 full-scale push-off tests. The tests were used to study the effects of the size of the gap between the ends of the precast slabs, and the amount of tie steel placed transversely across the joint, and the strength of concrete infill. Under certain situations the capacity of the stud is reduced compared with that in a solid reinforced concrete slab. Maximum resistances are compared with the predictions of BS 5950 and EC4, and a reduction formula for the precast effect is derived. D. Lam, K.S. Elliott and Professor D.A. Nethercot
