A STRUCTURAL NON-LINEAR DYNAMIC STABILITY AND A MATRIX FUNCTION METNOD[J]. Journal of Civil and Environmental Engineering, 1994, 16(1). DOI: 10.11835/j.issn.1674-4764.1994.01.014.
This paper presents a mathematical and mechanic model for non-linear dynamicstability analysis of structures on the basis of Liapunov's stability criteria. Due to the complexityand difficulty in numerical calculation
a matrix function to this type of stability problems is selectedand the programing formulations are derived.Applying the method to beam or frame structures un-der the axial period loadings
the geometric non-linear dynamic stability results are obtained.Fromthe results
the basic characteristics of this type of probtems
especially the non-linear effect areshown.The model and matrix function method are valtiable both in theory and in practice for struc-tural non-linear dynamic stability.
