In 2009–2022, to meet the requirement of resilient bridge pier structure (e.g., earthquake resistance, energy dissipation, isolation, resilience) for rapid repair after earthquakes and improve suitability precast segmental piers in medium- high-intensity areas, a assembled CFST with external replaceable dissipator was proposed. Based on ABAQUS finite element analysis software, model is establis...

One of the important issues in hydraulic engineering is inspection of local scour depth around bridge pier. Using piles is one of the ways for confronting local scour and erosion. In this study, the experiments were conducted in an 8m long, 0.5m deep and 0.25m wide flume. And the effectof using piles and number of them observed on the amount of scour in three different Frude numbers. The shape ...

Bridges are one the most important and useful river structure and as a key of Communication ways are very significant. Local Scouring is one the most reason of Instability of bridges and finally its failure annually immense human and financial cost to the government imposes. So far, several studies on ways to control and reduce scouring around piers of the bridges has been done among them, the ...
