Reliability Analysis of Partially Restrained Steel Connections
Publication: Journal of Structural Engineering
Volume 116, Issue 4
Abstract
The load and resistance factor design (LRFD) specification developed by the American Institute of Steel Construction allows the designer to consider the partial restraint in a steel connection. A generated nonlinear equation is fitted to available experimental data on partially restrained steel connections for six different types of connections. The connections analyzed are single web angle, double web angle, top and seat angle, end plate with column stiffeners, end plate without column stiffeners, and header plate. The statistics of parameters governing the moment‐rotation curves of the connection are determined. Design examples from the American Institute of Steel Construction Load and Resistance Factor Design Manual are used as an application of the use of statistical data in finding the reliability of a uniformly loaded, partially restrained beam. The reliability is evaluated by imposing end rotations and calculating the reliability index for each imposed deformation. The connection reliability index is the maximum reliability index for any imposed deformation. Both elastic and plastic behavior are considered.
