Finite element analysis up to failure of composite concrete – corrugated steel cylindrical shells

الملخص EN

This study presents three-dimensional finite element analysis to the behavior of composite concrete-corrugated steel cylindrical shell.

This type of construction utilizes the advantages of both of ordinary reinforced concrete and the composite action of cylindrical shell with corrugated steel plates.

The 8-node brick elements in (ANSYS v.9.0) have been used to represent the concrete, while the steel bars are modeled as discrete axial members connected with concrete elements at shared nodes with the assumption of prefect bond between the concrete and the steel bars.

The corrugated steel plate is modeled by four-node shell elements.

The interface elements are modeled by using three-dimensional surface to surface contact elements connected with the nodes of concrete and steel channel elements.

Comparison is made between the results obtained from the finite element analysis and the available experimental results of previous studies.
