摘要
基于超静定桁架的内力分布特点 ,调整杆长改变单元应力 ,使结构承载能力得到提高 ,通过几个例题验证了方法的有效性·
Based on the character of the internal force distribution of the statically indeterminate truss, the elements stresses were changed by adjusting the length of bars to increase load capacity of structure. The efficiency of the method is illustrated by several examples.
