Effect of flexible joints on the stability and large deflections of a triangular frame

Thacker, William I.Wang, Chang Y.Watson, Layne T.2013-06-192013-06-192007http://hdl.handle.net/10919/19615An isosceles triangular frame with rotationally resistive joints under a tip load is studied. The large in-plane deformation elastica equations are formulated. Stability analysis shows the frame can buckle symmetrically or asymmetrically. Post-buckling behavior showing limit load and hysteresis are obtained by shooting and homotopy numerical algorithms. The behavior of a frame with rigid joints is studied in detail. The effects of joint spring constant and base length are found.application/pdfenIn CopyrightProblem solving environmentsEffect of flexible joints on the stability and large deflections of a triangular frameTechnical reportTR-07-07http://eprints.cs.vt.edu/archive/00000942/01/triframe07.pdf
