Abstract
Experimental results of six full-scale specimens tested to investigate the behavior of mild steel connections for precast concrete shear wall panels are presented. The specimens were subjected to reversed cyclic combined flexure and shear in addition to constant axial stresses normal to the connection. The influence of cyclic vs. static loading, mechanical splicing vs. welding of reinforcement, and mechanical splicing vs. bolting of reinforcement to a tube section are discussed. Effects of the use of shear keys and partial debonding of reinforcement on the behavior of the connection are also presented. A simple analytical procedure is developed to predict the envelope of the cyclic response. Based on the findings, design recommendations for mild steel connections of precast concrete walls in seismic zones are presented. A numerical design example is included to show the application of the proposed design procedure.
