摘要
根据势能原理给出了一般层合材料杆自由扭转下的势能表达式,并根据最小势能原理及材料的等效应力应变关系进行了离心钢管混凝土构件在达到极限状态前的弹塑性刚度分析,为工程应用提供了一种方便可行的近似解法.
Based on the potential energy theory,a set of equations indicating the potential energy of the normal indurated layered member under torsion is put forward;And with the veference to the minimun potential energy theory as well as the relationship between effective stress and strain,the elastoplastic torsion rigidity of the centrifuge concrete filled walled steel tube approaching to the limit state is analyzed.Therefore,an approximate solution convenient and feasible for the related practical application in engineers is providod.
