of reinforced precast concrete structures in Italy that were
severely damaged by major earthquakes in May 2012, two
3⁄4-scale two-bay, three-story precast concrete frames with and
without cladding panels were subjected to a quasi-static cyclic
displacement history.

be used for moment resistance in any current building specification, they represent a promising solution when
included in modern steel moment resisting frames (MRFs), showing significant potential to mitigate some of
the major drawbacks inherently related to welded connections.
In order to quantify the influence of this attractive system on the global nonlinear dynamic response of whole
MRF buildings subjected to seismic loads, a numerical procedure, based on detailed three-dimensional solid
and one-dimensional fiber-based finite element (FE)models, has been developed and validated using past experimental
results. High-definition FE analyses, accounting for material and geometric nonlinearities, as well as for
the interaction among connection components via nonlinear contact algorithms, were able to capture stress/
strain concentrations that faithfully reflect experimental observations. By contrast, the mechanical modeling approach
discussed herein was applied to study these systems at a global scale.
This simplified FE idealization has been used to assess the seismic performance of T-stub connection systems,
within four- and eight-storey MRFs. These results were compared to those for other top-and-seat angle joints investigated
in a past research program. A series of conventional and adaptive pushover analyses and incremental
dynamic simulations have been carried out, using a suite of 44 records as seismic input, to quantify behavioral
changes in the response of MRF systems as a function of geometric variations in the connection.
