The Algerian seismic code assumes that the beam-column joints in monolithic reinforced concrete (RC) buildings are fully rigid. However, many experiments have proven the existence of relative rotations in these connections, and then the…

Impact response of different materials for sports mouthguards

Maria Moreira, João Carlos Ramos, Ana Messias, Maria Augusta Neto, Ana Paula Amaro, Paulo NB Reis

Up to this moment, there is no guideline regarding the materials to produce mouthguards. The most used is Ethylene-Vinyl Acetate (EVA). Studies indicate that laminating EVA sheets with rigid components could increase the protection…

Degradation of the first frequency of an RC frame with damage levels

Quy Nguyen, Ramazan Livaoğlu

Damage in RC structures causes the degradation of stiffness and frequency parameters. In this study, the relationship between the two coefficients and damage severities is numerically investigated considering a three-dimensional (3D)…

Residual stresses caused by static and dynamic contact interaction of composite plate and steel spherical indenter

Sviatoslav Eleonsky, Vladimir Pisarev

A new approach has been developed and implemented to determine the main components of residual stresses that arise as a result of the contact interaction of a spherical indenter and a flat surface of composite plate made. The experimental…
