Abstract

The invention provides an anti-seismic composite height adjustable steel support of a high-pile wharf and belongs to the technical field of building earthquake resistance. A top support, a standard module support and a bottom support are overlapped up and down. The lower end of the bottom support is fixed to a pile cap. Fiber-reinforced high-damping elastic rings are arranged between the top support and the standard module support and between the standard module support and the bottom support and are in elastic connection with the top support, the standard module support and the bottom support. The anti-seismic composite height adjustable steel support can resist earthquake loads in all directions well, has certain deformation-recovery capability, can make up the deficiency that the elevation of a pile does not reach the specified value due to the fact that the designed pile length does not satisfy the actual situation or due to the causes of construction through the adjustable heightof the support, is protected against large displacement under the action of an earthquake, has the advantages of being adjustable in height, capable of omni-directionally consuming earthquake energy,suitable for the high requirement for stress deformation of a port engineering structure and the like, is simple in mounting process, low in manufacturing cost and capable of realizing mass productionand has wide applicability.

Description

technical field [0001] The invention relates to an anti-seismic composite height-adjustable steel support for a high-pile wharf, which belongs to the field of anti-seismic technology for buildings. Background technique [0002] Ports are essential transportation hubs that play a vital role in the economic development of societies. However, most of the coastal cities in my country are located in the earthquake zone. The examples of earthquake damage in the past show that once the port project suffers from an earthquake disaster, it will not only have a serious impact on the economy, but also cause a large number of casualties. Due to the softness of the foundation soil of the port project, if the foundation soil liquefies under the action of an earthquake, it will not only amplify the earthquake effect but also cause severe shear failure of the pile foundation. [0003] At present, in engineering practice, it is often considered to install spring isolation bearings between t...
