| This paper presents a thorough investigation into the structural performance of
cold-formed steel column base and beam column connections using single lipped C
sections with bolted moment connections. Two specimens consisting of a column base and
a beam column connection were carried out, and it was found that section failure under
flexural buckling was always critical. Moreover, the proposed connections were
demonstrated to be structurally efficient attaining moment resistances close to those of the
connected sections.
In order to examine the structural behavior of the column base and beam column
connections, finite element models were established using shell and bar elements to model
the sections and the bolted fastenings respectively. Material non-linearity was
incorporated, and comparison between the test and the numerical results was presented in
details. It was shown that the proposed analysis method was structurally adequate to
predict the structural behavior for column base and beam column with similar connection
configurations. |
