Abstract

The PDT (pseudo-dynamic test) method for assessing structural performance during a severe dynamic event such as a strong earthquake, combines on-line computer simulation of the dynamic aspects of the problem with experimental information about the structure, acquired quasi-statically, to provide realistic dynamic response histories, even for the non-linear behaviour of severely damaged structures. This allows the time-scale of the test to be extended, thus permitting large scale testing without the need for very high hydraulic power and very fast acting actuators and control systems. An overall description of the PDT method as used in a Reaction-Wall facility is given together with its merits; its limitations and potential developments are also described. The algorithmic aspects of the computer simulation are then explored in more detail and the essentials of the hardware and the servohydraulic control system required are described. Finally some conclusions are drawn as to the current status of the method.
