Influence of Transverse Bar Position in Hole on Mechanical Behavior of Perfobond Rib Connectors

Abstract:

Basic mechanical behavior parameters of perfobond rib connector with transverse bar in the hole are obtained based on the state that transverse bar is located in the center of the hole.However,the position of transverse bar in the hole usually deviates from the hole center during actually construction.Nine groups,totally 27 specimens with perfobond rib connectors are designed and pushout tests are performed to investigate the influence of transverse bar position changes in the hole on mechanical behaviors of perfobond rib connectors.The test results show that transverse bar position changes have much more influence on ductility and stiffness of perfobond rib connectors rather than carrying capacity.Finally,the shear stiffness calculation expressions of perfobond rib connectors under different mechanical behavior are proposed.
