Abstract The parameters optimization of a viscous damper is carried out with cable-stayed bridge single cable plane and tower. Based on five four functions energy dissipation structure, the relationship between each function obtained. Finally, spatial distribution surface multi-parameter objective constructed, final result process shows that reasonable can effectively inhibit vibration structur...

Abstract This article presents the performance of cable-stayed bridge by representing a model using ANSYS program under influence concentrated load and then comparing them with experimental results. One was used in analytical, one (harp type 1) length girder (4,500 mm), height pylon (1,480 depth flange for (40 mm). If bridges are constructed balanced cantilever method, stability problem is more...

Abstract An extradosed cable‐stayed bridge employs a structure that combines the main elements of both prestressed box girder and bridge. In to apply optimization, because this type has hybrid nature; bridges have significant additional complexity oversizing [7]. This research paper evaluated optimum depth with pylon height, angle stay cable, effect concrete grade on those three parameters an c...

Long-span cable-stayed bridges are subjected to the risk of collision from passing ships. Conducting experimental study on and vessels is difficult due high cost limited space. In this paper, behavior a 1[Formula: see text]018-m long-span bridge ship collisions numerically studied. Finite element models entire ships established. Four different dead weight tonnages (DWT), namely, 2[Formula: text...
