This paper presents a method of using the principle of virtual displacements directly to obtain the ordinates of the influence line for frames. As comparing with routine approaches, its basic concepts are brief and clear, and the process of calculation is fairly simple. The method suits programming well, and can also be used to construct the influences lines for continuous beams with constant cross-section. With some modification, it may be used for frames with variable cross-section....
