Test Study on the Axially Pulled Capacity of Prestressed Concrete Pipepile - Pilecap Connection Joints
Using prestressed concrete pipepile with 550mm diameter, the axially pulled capacity of plie-pilecap connections is studied by testing nine members. Pile-pilecap connection types, the failure form of connections, failure mechanism and tension character are discussed. Some formulae for calculating the axially pulled capacity of connection and determining the embedded length of pilebody in pilecap are proposed based on the tests, at the end a reasonable connection type is proposed for engineering.
