Behavior of Grout Sleeve Connections under Eccentric Cyclic Load

摘要

The grout sleeve connection offers important complement to traditional steel tube connections and is increasingly applied in structures. To acquire the connection's behavior under eccentric cyclic load, study and tests were conducted at Tongji University on two specific types of grout sleeve connections which were identical except for some construction measures. The load-strain curve, load-deformation curve, elastic limit bearing capacity and stress-strain distribution of each specimen are obtained as results. Those results indicate that this kind of connection has good bearing capacity and stiffness, and those behaviors can be efficiently improved through optimizing its construction measures.
