摘　　要：定性结构力学好似进入瓶颈期,为推动定性结构力学的发展,针对超静定桁架进行了定性分析示例,从荷载、支座移动、制造误差、温度改变等四个方面展开分析,以变形趋势作为基本思路,把拉压杆的判断、各点位移的分析以及是否为主要受力构件等作为超静定桁架定性分析的主要指标。Qualitative structural mechanics seemingly is going through a bottleneck period.Some examples of statically indeterminate trusses are analyzed in order to promote qualitative structural mechanics.There are four aspects are considered,such as load,support settlement,manufacturing error,temperature change and so on.The analysis of deformation trend is regarded as basic guideline.The judgments of tension members or compression members,the displacement estimations of some points,and the main stress components whether or not are discussed mainly for the statically indeterminate plane trusses in this paper.
