| Abstract: |
A socket connection is one of the emerging and most recommended joint connections in prefabricated substructures. At present, a large number of researches on socket connections has been carried out and most of them deal with pier-spread footing in the shallow foundation. This paper aims to study the effect of axial compression ratio using quasi-static tests of 2 specimens with socket connections. Specimen M1 is subjected to vertical and horizontal loading, whereas Specimen M2 is subjected to horizontal loading only. The experimental results showed that the axial compression ratio has a huge influence on the socket wall stress, i.e., the greater the axial compression ratio, the greater the socket maximum wall stress. But under the same horizontal force, the greater the axial compression ratio, the smaller the socket wall stress. And during increment of axial compression ratio, horizontal bearing capacity and horizontal stiffness of pier increase significantly. |
