| Abstract: | This paper studies the stress of the beam column joint with gap graded concrete in supertall reinforced concrete structure,taking into account of the scheme of the distribution of reinforcement using a multi level substructuring technique of the finite element method.The distribution of stresses and the ranges of stress concentration are determined by more than 100,000 freedom analysis of FEM.The numerical results in the present paper are significant for improving the designs of the reinforced concrete beam column joints. |
