The objective of this research was to identify the failure modes associated with this type of connection. A subset of all the available beam sizes from the AISC Manual was selected, considering that there are no experimental results for beams under the W21 series. Four prototype buildings were designed according to the Chilean seismic code for buildings, considering the flexibility of the connection, and complying with the seismic compactness and strong column-weak beam requirements set forth by the AISC seismic provisions. The structures designed had the same 36 meters by 54 meters floor plan, uniform story height of 3.5 meters and distance between columns of 9 meters, but different number of stories (three, six, nine, and twelve). A few beam/column combinations were selected from the prototype buildings and different connection configurations were designed for each combination to represent several failure modes reported in the literature. These configurations were represented numerically through 3D finite element models, using ANSYS. The models were subjected to monotonic loading up to the full plastification of the beam cross section in flexure. The results show that it is not possible to draw general design and modeling recommendations for the connection based only on the response of the isolated T stub, and that the conditions imposed by the beam must be considered. The results of the numerical models will be validated with the results of full size beam columnconnection specimens to be tested.
