Abstract This paper describes an experimental investigation into confinement effects provided by circular tubular sections to rubberised concrete materials under combined loading. The tests include specimens with 0%, 30% and 60% rubber replacement of mineral aggregates volume. After describing the arrangements specimen details, results bending eccentric compression are presented, together compl...

This paper provides both an analytical and a finite element models aiming at better predicting possible perforation of reinforced concrete slabs submitted to impacts. Both account for free water saturation ratio high triaxial stress induced into by the impact. Finite simulations are performed with Abaqus explicit code using revised constitutive model concrete; this coupled damage plasticity (PR...

Lightweight foamed concrete (LFC) is a low-density with numerous applications. However, because its weight nearly half that of traditional concrete, strength can also be expected to reduced. This research investigates the possibility using LFC reinforced alkali-resistant woven fibre mesh improve mechanical properties. One key issues lightweight construction deterioration steel, which has consid...

In recent years, the Lamb wave analysis by the multi-channel analysis of surface waves (MASW) for concrete structures has been an effective nondestructive evaluation, such as the condition assessment and dimension identification by the elastic wave velocities and their reflections from boundaries. This study proposes an effective Lamb wave analysis by the practical application of MASW to concre...

We analyze the concrete security provided by a signature scheme described in a recent Internet Draft by McGrew and Curcio.
