【摘要】 从熟知的虚功原理出发,应用单位荷载法,对支座移动作用下板壳结构的位移计算进行了研究,并给出一个定理,板壳结构在只承受支座移动作用时,位移计算公式中不显含结构中的内力项,位移的值仅与支座移动有关。因为不需求出结构中产生的内力,就可计算位移,这样使位移计算大为简化。给出的定理系首次提出,它既有理论意义,也有实用价值。更多还原

【Abstract】 Based upon the principle of virtual work,unit-load method for the research of the displacement calculation of plate and shell which subjected to support’s Transfer loading is presented.A theory is presented that the displacement’s calculation formulation doesn’t explicit content structure’s internal force term and the displacement is only relative to the support’s displacement when plate and shell structure subjected to the support’s transfer loading.The structure’s displacement can be obtained when the structure’s internal force is unknown that would greatly simplify the calculation of structure’s displacement.The theory is provided for the first time,it not only has very important theory significance but also has practical value.更多还原
