Abstract

In reinforced concrete industrial precast structures one of the most common seismic damage is the collapse of the cladding panels because of the failure of the panel-to-structure connections. This damage is caused by the interaction between the panels and the structures, which is usually neglected in the design approach. The present study aims at investigating this interaction. Nonlinear dynamic analyses are performed on several structural models in order to take into account both the panel-to-structure interaction and the roof diaphragm. According to the analyses results, if the current European single-story precast buildings stock is considered, panels stiffness significantly influences the overall structural behavior under seismic actions and the failure of the connections occurs at very low intensity values. The progressive collapse of the panels is also simulated in order to evaluate the redistribution of seismic demand in the columns during the earthquake. In the final part, fragility curves are evaluated in order to generalize the dynamic analyses results.
