Strength and Stiffness of Corrugated Rib Connector

Abstract:

Connectors are the key element in steel and concrete composite structure. To research and develop new type connector for steel and concrete composite structure, a new type connector, corrugated rib connector, was developed. The base mechanical properties of this connector were tested by push-out tests. The test results shown the mechanical properties of this connector are excellent. Comparing to the push-out test results of perfobond rib connector, the shear strength of corrugated rib connector increased 24 percent than that of the perfobond rib connector, and the shear stiffness of corrugated rib connector is larger than that of the perfobond rib connector, Especially the ductility of corrugated rib connector is 1.9 times that of the perfobond rib connector when they reach the ultimate load. Based on the load-slip relation of corrugated rib connector by push-out tests, relative stiffness expressions under normal service state and ultimate bearing capacity state are obtained.
