Joint for prefabricated concrete blocks in non-plastic hinge zone of earthquake-resistant pier

Abstract

A joint for the prefabricated concrete blocks of the quake-resistant pier developed for connecting the prefabricated reinforced concrete blocks employed in the non-plastic hinge zone of the earthquake-resistant reinforced concrete pier comprises mainly an upper prefabricated reinforced concrete block and a lower prefabricated reinforced concrete block, wherein a layer of resin binder is applied between the engaging concave and the engaging convex of the prefabricated reinforced concrete blocks, so as to connect the two prefabricated reinforced concrete blocks to withstand shear stress applied on the pier, and the two prefabricated reinforced concrete blocks are also connected firmly by pre-stressed keys to withstand bending stress applied on the pier. By connecting mechanisms, the present way of prefabricated construction can achieve the same earthquake-resistant capability as the traditional in situ construction.
