The AASHTO code of practice for design of bridges shows that the ductility level for foundation is given equal to one. Bridges are classified in three classes. For class of essential and normal bridges a question for not to use ductility level due to the importance of bridges’ costs is become an important item in different countries particularly in Middle east. This paper aimed to study on pe...

The article considers peculiarities of operation and monitoring low-level bridges which are found on highways regional, intermunicipal, local significance. vibrations the bridge superstructure considered in detail taking into account its interaction with other elements structure environment. It is proposed to use natural frequency vibration as a characteristic, change takes condition structure.

ALTHOUGH MANY STUDIES HAVE SHOWN an association between operating heavy construction equipment and symptoms of musculoskeletal disorders (MSDs), little research has been performed that systematically characterizes the exposure of operating engineers to ergonomic hazards. This study evaluated: 1) vibration at the seat/operator interface; 2) transmissibility of vibration in the Z-axis; 3) psy-cho...

Abstract Along with the advancement in sensing and communication technologies, explosion measurement data collected by structural health monitoring (SHM) systems installed bridges brings both opportunities challenges to engineering community for SHM of bridges. Deep learning (DL), based on deep neural networks equipped high-end computer resources, provides a promising way using big address prob...

In Local Area Networks (LAN) connected together by bridges, flow control and smooth traffic in the network is very important. However, congestion at bridges can cause intensive loss of received frames. In addition, the received frames are thrown away and have to be retransmitted by the source station, which causes more congestion and massive reduction in the overall network throughput. The netw...
