【摘要】 根据势能原理方法,给出了一般硬化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.更多还原

【Abstract】 Based on the potential energy theory,a set of equations are puts forward indicating the potential en- ergy of the normal indurated layered structure under torsion.The elastoplastic torsion rigidity of the centrifuged concrete filled thin-walled steel tubes before achieving the ultimate strength in analized by using the mini- mum potential energy theory as well as the relationship between effective stress and strain.Finally,an approx- imate solution for related practical projects is provided in this paper.更多还原
