this article considers the seismic behavior of beam-to-column joints in steel frames for different bolt arrangements by using of finite element modeling. as the most important beam-to-column joint type, the beam-to-column joints with end-plate is chosen for the analysis. four different specimens have been analyzed. these models had some differences such as bolt arrangement and the presence or a...

In this paper, an experimental and numerical study was adopted to investigate the effect geogrid soil reinforcement prestressing on the pressure settlement relation of sand bed supporting a strip foundation. The studied parameters include foundation depth and pre-stress ratio for the cases of one and two pre-stressed reinforcement layers. The study reflected that pre-stressing of soil reinforce...

Residual stresses in fibre reinforced composites can give rise to a number of undesired effects such as loss of dimensional stability and premature fracture. Hence, there is significant merit in developing processing techniques to mitigate the development of residual stresses. However, tracking and quantifying the development of these fabrication-induced stresses in real-time using conventional...
