Apr 12, 2021 As one of the main load-carrying components of cable-stayed bridges, bridge towers are typically required to remain elastic even when subjected to severe ground motions with a 23 probability of exceedance in 50 years. To fulfill this special requirement imposed by current seismic design codes, reinforcement ratios in the bridge towers have to be kept significantly higher than if
For earthquake simulations, one of the services we provide are shake tables. Currently, there are two, relocatable, 7.0m x 7.0m platforms with six-degrees of freedom. Each table is capable of 50 tons payload. A 3.6 x 3.6 meter table platform of welded steel construction with a weight of ...
