摘要
Abstract
According to the theory in basal mechanics, this thesis predigested the mechanical mode of the double reinforced rectangular concrete column, built the mechanical balance equation, and analysed stress process of the pier in theory. Under the condition that regarding concrete is being pulled, we should search the position of neutral axis of the cracking section by "three-phase" theory in order to get function expression of the concrete's resisting power along the length direction of the pier. These calculated results can be applied to the deformation analysis of the reinforced concrete cantilever bridge piers; and " three-phase " theory can be used to calculate stiffness of pier's each section; and the displacement of pier's top; and then be helped to do cracking mechanism of reinforced concrete piers under complex loads.关键词
