An approximate analysis of rigid frames using a new concept, called the stiffness center, is presented. It has been shown that when a skeletal elastic system is idealized as a configuration of elastic springs, about such a center the stiffness of the system is balanced. The concept of elastic center is closed-ring types of structures, the instantaneous center-of rotation in a group of fasteners, the center of gravity in the centilever method, the neutral axis in solid as well as in composite cross sections are all special interpretations of the stiffness center. The method is compared with the existing approximate methods.
