Feasibility Study of Partially Restrained Connections

Abstract

In recent years the idea of using partially restrained connections in building structures has become more practical and economical. Partially restrained connections resist moment and also allow rotation, therefore distributing the moments and stresses more evenly throughout the element. Combining this idea with steel joists, which are also quite common in construction, makes for shallower story heights and lower steel weights. This initial study analyzes partially restrained connections for both hot rolled shapes and steel joists using non-composite and composite construction. The designs are than compared with respect to complexity, practicality, serviceability and economics. The results of this study show that partially restrained joist connections are economically superior to comparable hot rolled member designs.
