Abstract

Damage observed in existing structures after recent earthquake events pointed out the key importance of beam-to-column joints in influencing the global response of reinforced concrete structures. In the last two decades several theoretical and empirical models have been proposed for evaluating the shear strength of beam-to-column joints. The present paper reports an overview of the models currently available in the scientific literature for evaluating the shear capacity of exterior beam-to-column joints. The present study is the first step of a wide analysis aimed to assessing such models and improving them. Moreover, the uncertainties deriving by applying the mentioned models will be also quantified therein, by means of well-established procedures for probabilistic seismic analysis of structures. The final results of that study are reported within a companion paper.
