Problems solved by technology

[0003] Existing bridge segment model wind tunnel test devices are usually placed outside the wind tunnel wall, which can reduce the influence of the device on the test wind field, and can also realize tests under different wind attack angles, but the segment model cannot be realized. Tests at different wind angles
And the traditional segmental model wind tunnel test device is usually two separate devices for static test and dynamic test, which increases the test cost

Abstract

The invention discloses a testing device with static and dynamic test functions of a bridge segment model. The testing device comprises a bridge segment model static test device and a bridge segment model dynamic test device. According to the invention, the testing device with the static and dynamic test functions can be used for dynamic testing through simple transformation on the basis of an original static testing device. Compared with a traditional segment model wind tunnel test device which is usually divided into two sets of devices for static test and dynamic test, the testing device provided by the invention can greatly save the test cost and improve the test efficiency.

Description

technical field [0001] The invention relates to the technical field of bridge segment model tests, in particular to a test device with both static and dynamic test functions of bridge segment models. Background technique [0002] In recent years, with the construction of offshore bridges, a large number of long-span or even super-long-span bridges have emerged. The increase of bridge span necessarily means the decrease of structural stiffness and damping, which makes such structures more sensitive to wind. Moreover, the environment where the cross-sea bridge is located usually faces severe wind, wave and sea conditions, which makes the stress of the bridge structure even more unfavorable. In the actual wind and wave environment, there will be obvious non-orthogonal phenomena between the incoming wind direction and the bridge in the horizontal direction, that is, there is a wind deflection angle; there will also be obvious non-orthogonal phenomena between the incoming wind d...
