However, among horizontal beams, those that bear horizontal forces and act as part of the framework are sometimes called beams, while those that only bear vertical loads without considering horizontal forces are called lintels. Structures using columns and beams are called rigid frame structures, while those that are not like that and are like simple building blocks are called post-lintel construction. …
