Abstract
A flat shell element is generated by way of the practicable hybrid FE algorithms for high speed engineering applications on a PC. The element is four-noded and is described by a simple stress field and a displacement field characterized by six physical degrees of freedom per node, achieving interelement slope continuity. The performance of the element is tested against typical benchmark test problems and found to be highly accurate. This flat shell element is employed in modeling a bridge structure and the FE results are compared with the in situ test measurements. It is shown that the FE model based on a few hundred flat shell elements can achieve high accuracy on a PC within a few minutes of CPU.
