Bridge bearings are a small part of the whole bridge structure, but it can affect corner bridge, and stability quality deck, so performance bearing directly determine lifespan entire bridge. The connects upper lower parts In order to improve structure layout selection needs be done well, construction process closely monitored, well-managed. existing problems should analyzed in detail solved tim...

This article studies a concrete hollow slab simply supported-continuous actual engineering project in certain city. Before the reinforcement of bridge, there were cracks and exposed rebars, etc. In order to ensure safe operation method was adopted, prestressed steel strands are used convert simple-supported structure into continuous structure, thereby improving structural load-bearing capacity ...

To improve the limiting capacity of isolation bearings and reduce residual deformation, a new material shape memory alloy (SMA) was introduced into damping device. SMA materials have effect, superelastic properties metal alloys. Although bearing can self-resetting ability bridge, it will increase internal force response substructure compared with ordinary bearing. solve this problem, type negat...

UNLABELLED Implant-supported screw-retained fixed dental prostheses (FDPs) produced by CAD/ CAM have been introduced in recent years for the rehabilitation of partial or total endentulous jaws. However, there is a lack of data about the long-term mechanical characteristics. OBJECTIVE The aim of this study was to investigate the failure mode and the influence of extended cyclic mechanical load...
