| Abstract: | In view of the shortcoming of reinforced concrete plane finite element models,the quadrangle compound models on reinforced concrete plane finite element in various forms of bars arrangement are established And the general expressions of the stiffness matrix of each type of the elements are worked out By the contrastive analysis with the dispersion model,the compound model fits with the basic theory on finite element disperse,and can more exactly reflect the real structural function of bars as well Furthermore,the model has more practicality |
| Keywords: | reinforced concrete finite element model of element stiffness matrix |
