Dsk. Lo et Sf. Stiemer, A PRACTICAL METHOD FOR INCORPORATING FLEXIBLE CONNECTIONS IN PLANE FRAME ANALYSIS, Canadian journal of civil engineering, 22(5), 1995, pp. 871-882
A practical method for incorporating realistic flexible connections in
plane frame analysis, including the effect of connection sizes and sh
ear deflection, is presented. The general algorithm can be easily impl
emented in a standard plane frame analysis program and, once implement
ed, it can be an ideal tool for production work in the steel industry.
Connection stiffness is programmed directly into the analysis using t
he moment-rotation equations developed by Frye and Morris or may be en
tered separately as data. practical application of this method of anal
ysis is demonstrated by modifying a standard plane frame analysis prog
ram to include the effect of flexible connections. Solutions obtained
using this modified program, CPlane, were verified against the finding
s of Moncarz and Gerstle. A simple plane frame structure was analyzed
under various lateral load intensities for different connection assump
tions. It was found that the inclusion of connection behavior signific
antly altered the internal force distribution and design of the struct
ure.
