Coventry Cathedral was completed in the early 1960s and has some prestressed concrete elements to resist lateral thrust from the roof. Other prestressed structures of a similar age have had corrosion problems and this has drawn attention to the fact

To determine the load at which FRPs debond from concrete beams using global-energy-balance-based fracture mechanics concepts, the single most important parameter is the fracture energy of the concrete–FRP interface, which is easy to define but diff

Fibre-reinforced polymers (FRPs) have not captured the market for reinforcing bars, or found uses even as external prestressing tendons, despite their obvious advantages in terms of lack of corrosion. This paper considers the constraints that underli

Creep tests at ambient conditions have been carried out on Kevlar 49 and Technora yarns cover- ing a wide stress spectrum (10-70% average breaking load) for a long period of time (up to a year). The results confirm that Kevlar 49 and Technora yarns s

This article presents results from conven- tional creep tests (CCT) and two accelerated test methods (the stepped isothermal method (SIM) and the stepped isostress method (SSM)) to determine the creep and creep- rupture behavior of two different aram

A new accelerated technique, called the stepped isostress method (SSM), is presented that allows accelerated testing of materials to determine their creep response, and in particular, their creep-rupture behaviour. The approach in SSM testing is simi

The debonding of FRP plates from concrete beams is not amenable to finite-element analysis; fracture mechanics, based on a global energy balance, offers a better alternative. An analytical model with energy calculations based on a revised version of

Vast governmental budgets are spent annually to face corrosion problems of steel reinforcement in concrete bridges attributable to the extensive use of deicing salts. Corrosion controls the lifetime of a bridge, which has two distinct periods. During

This paper examines the environmental conditions under which the time to cracking of concrete, due to pressure caused by rust production on the surface of steel bars, is short. To determine this time, volume compatibility is assumed, which allows for

Hip fracture risk rises 100- to 1000-fold over six decades of age, but only a minor part of this increase is explained by declining BMD. A potentially independent cause of fragility is cortical thinning predisposing to local crushing, in which bone t
