Using a specially designed lever arm, full-scale fatigue tests of a cable-to-steel orthotropic bridge deck connection were conducted in the National Center for Research on Earthquake Engineering (NCREE).
A total of 87 cold-formed stainless steel single shear bolted connections was conducted.
Given this limitation, a finite element analysis (FEA) parametric study of steel girders containing idealized connections was conducted to better understand connection demands in this situation.
An experimental study on four full-scale specimens, including two SMA-based bare steel connections and two composite connections, is conducted.
Three series of six full-scale, cyclic tests on post-tensioned (PT) beam-to-column connections were conducted to evaluate the cyclic performance.
Therefore, a parametric study on the compressive strength of BRBF central gusset plate connections is conducted with various gusset plate dimensions and free-edge stiffeners.
Full-hole embedment tests of screw-reinforced LVL specimens up to dowel displacements of two times the dowel diameter and thus, representative for highly ductile dowel connections were conducted.
Full-scale tests on beam-to-column high strength steel endplate connections were conducted at elevated temperature 550 °C under steady state fire condition and at ambient temperature as reference.
Finally, a preliminary numerical prediction of the lateral load carrying capacity of LGM shear walls with these connections is conducted, in order to address the potential of LGM to be used as a structural material in bamboo-framed shear walls, as an alternative to conventional wood-framed construction.
As part of this research, nonlinear pushover and transient analyses of 4-, 8-, and 16-story frames with RBS connections are conducted with the objective of developing a better understanding of RBS frame behavior and exercising as well as critiquing the recently published FEMA-350 design specifications.
