A Method for System Buckling Analysis of Plane Sway Frame Kuinian Li School of Civil and Environmental Engineering University of the Witwatersrand, Johannesburg Private Bag 3, Wits 2050 RSA Email: Kuinian.li@wits.ac.za KEYWORDS: System buckling, Negative stiffness, Modification factor, Second order analysis ARSTRACT: Presented in this paper is a simple and practical method for buckling analysis of the overall structural system.
This interdependency has rarely been accounted and the stability of a whole structural system is still estimated by evaluating the stability of its component members in engineering practice.
It is true that the easy accessibility to computers and availability of computer programs has made the system buckling analysis of a whole structural system closer to engineering practice.
However, such system buckling analysis approach can not be called popular in general engineering practice yet.
However, with this approach, for a two story one bay plan sway frame, to get the buckling load with reasonable accuracy, a stiffness matrix needs to be formed and the eigenvalue problem be solved, which can not make it attractive to practicing engineers.

At the same time, there are still shortcomings affecting the implementation and integration of new engineering approaches to solve the need for new materials and technologies that constantly address issues such as viable product maintenance, performance, costs, and environmental impact concerns.
For example, it was estimated that the average age of the passenger aircraft carrier fleets is approximately seven years, the average age of their cargo counter parts is approximately twenty eight years [7], and the impact of maintenance costs for both civil and military aircraft is at least two to three times greater than initial purchase values, and this trend is expected to increase [8].
