More Information
Summary:The hierarchical reinforced concrete element is proposed for efficient global analysis of steel-concrete mixed bridges with prestressed concrete deck slab. In this element, reinforcing bars that are represented by cable elements are embedded in a solid element, and a displacement function of the reinforcing bar is expressed by generalized displacements of a solid element. As such, the element division is not necessary at the position of reinforcing bars and many reinforcing bars can be arranged in any direction into the solid element. Furthermore, a curved tendon is represented by a mapping cable element considering the initial stress.
