Abstract:
The strength and ductility of several tilt-up concrete wall panel connections are investigated analytically and experimentally in a series of monotonic and cyclic tests. For the connectors loaded in tension, experimental results do not support the capacity predictions based on the analysis, due to cone failure in the thin concrete sections. The tension tests showed good agreement in load-deflection behavior between monotonic and cyclic loading, indicating that simple monotonic testing would be adequate for further investigation of the strength and ductility of these connector types. The shear results demonstrated significant differences in load-deflection behavior between monotonic and cyclic loading. Most of the connector types tested did not show sufficient ductility to be used where ductility was a requirement. Further development is needed to produce economical connectors that demonstrate adequate ductility where required
