Special Finite Elements Used in Reinforced Concrete Analysis

Abstract

Finite element method was developed to be applied in case of the elastic materials. If this method is applied on reinforced concrete elements and structures, the results are affected by errors because this material doesn’t have an elastic behavior on loads. Because the reinforced concrete has cracks in service, the evaluation of reinforced concrete structures with finite element method requires some improvement of the method to obtain the results without errors. The paper presents a special type of finite element who can describe, with mathematical relations, the behavior of the reinforced concrete.
