Resumo(s)
In recent earthquakes, it has been observed that precast RC structures has shown,
in several cases, a poor performance presenting damages on structural and non-structural
elements, highlighting the vulnerability of industrial buildings. Beam-to-column connection
was pointed as one of the main source of damage. Precast concrete buildings are common in
the industrial parks. One-story industrial building constituted by a frame system of beams and
columns, with hinged beam-to-column connection are the most common structural
configuration. In this way, it is important to characterize this type of buildings to understand
its seismic behavior in order to develop new methodologies and solutions for design this type
of buildings and improve your performance. The presented work is focused on beam-tocolumn connections that play a determining role on precast structures. The proposed work is
the review of the different strategies to model beam-to-column connections in a precast
industrial RC building is presented. To perform the analyses, the structural software
Opensees was chosen. Nonlinear static analyses were performed. The results are presented
and discussed.
