【Abstract】 Aim. In constructing high buildings,it is highly desirable to have a platform that can move quickly up and down to allow workmen gain easy access to the places they are to work on.Such a platform needs to be supported by a steel framework,whose buckling under specified loading must be guarded against in compliance with GB50017-2003,a Chinese government specification on steel framework.In the full paper,we explain in some detail our stability analysis of the steel framework we design and the comparison of the buckling load calculated with our method with that calculated by the commonly used practical engineering method.In this abstract,we just add some pertinent remarks to listing the three topics of explanation.The first topic is: the brief description of the steel framework we design.The second topic is: the simplified model for the stability analysis of the steel framework.The third topic is: the stability analysis of the steel framework.In the third topic,we first explain the calculation of the buckling load with the help of finite element analysis;the buckling loads accurately calculated with ANSYS tool box are summarized in four figures in the full paper.Also in the third topic,we explain how to calculate the buckling load approximately with the commonly used practical engineering method.Still in the third topic,we compare the accurate buckling loads calculated with ANSYS tool box with the approximate buckling loads calculated by the practical engineering method in two figures in the full paper.The comparison shows preliminarily that the two methods are in agreement,thus confirming that the steel framework designed by us has enough reliability.更多还原
