Drilling degrees of freedom for 2D and 3D elements and applications in building structures

摘要

In analysis of large-scale and complicated structrues, compatibility in rotations of various-types of element, such as frame, membrane, solid element, etc., should be carfully taken into account. Otherwise accuracy will be lost seriously. Introducing drilling degrees of freedom (DOFs) to 2D and 3D continuum elements will solve this problem reliably and conveniently.
