Abstract
The dynamic response of elasto-plastic frames and arches is investigated using a discrete system approach. The governing equations of motion are formulated through the virtual work principle and supplemented by the compatibility conditions established through the conjugate segment analogy. Time marching is carried out through direct time integration process using backward differences. The method, requiring small core storage and short computer time, can be easily implemented on any personal computer.
