摘要
Abstract
In this paper,a finite element method is proposed for mass concrete reinforcement in pre-embedded parts under three-dimensional stress states.Concrete stress-strain relationship and theoretical strength analysis considered the whole concrete stress-strain curve,strength of the failure envelope surface under the triaxial stress states.The steel rebar is simplified as the entity elasto-plastic model of the different nature.The reinforcement adjustment is done indirectly by adjusting the mechanical parameters of the soild elements,and is equivalent to the yield stress with different elastic moduli according to the reinforcement ratios under different elastic moduli.When the load increased steadily under a proportion loading design load,the mechanical parameters were then converted into solid unit amount of steel reinforcement.Combined with ADINA software,the material parameters and material model in the software were employed.关键词
