Dynamic behavior of ancient frames consisting of classical columns with architrave

摘要

This paper deals with the dynamic behavior of ancient frames consisting of two classical columns with an architrave resting on them. This free-to-rock plane frame is studied through a simple analytical process after some generally accepted simplifications. Furthermore, an analytical approach method for the solution of the fully nonlinear system of equations of motion (including the vertical component of earthquake excitation) is proposed, while the corresponding static and dynamic conditions against rocking and sliding are studied in detail. Finally, some characteristic examples are presented and useful conclusions are drawn.
