Both the bridge girder and the connection between the bridge girder and each pontoon are modelled as equivalent single beams with the cross-section properties listed in Table 1. When extracting the internal forces in the post-processing the effect of local stresses is neglected. For instance the ...

Pressurised wind tunnel observations of the Strouhal Number at high and low Re for the bridge girder cross section in question was supported by observations of vortex induced vibrations of the prototype bridge girder and the corresponding 1:80 scale section model tested in a conventional low speed ...
The numerical technique is applied to two famous long-span bridge decks (the Normandy cable-stayed bridge and the Great Belt suspension bridge), presented by different cross section geometries and various aerodynamic characteristics. The obtained results are compared with each other and with wind-...
The ultimate tensile strength (UTS) equals the maximum stress (Fmax) divided by the cross section value before the tissue failed when being stretched. The strain at maximum force (SFmax) reflects how much the sample was strained at the point of the UTS compared to its initial length. Full ...
GUANGZHOU, Sept. 6 (Xinhua) -- Construction of a bridge section of a highway linking south China's Shenzhen and Zhongshan started Thursday, the Guangdong provincial transportation group said. The total length of Shenzhen-Zhongshan highway will be 24 kilometers and include an underwater tunnel an...
You can use either a crossover cable or a straight-through cable. Step 3 Connect the power injector to the access point/bridge using dual coaxial cables. Step 4 Connect the power injector power cable and power up the access point/bridge. Step 5 Follow the steps in the "Assig...
