Abstract
An adaptive finite element code using the linear Timoshenko beam elements
based upon the adaptively shifted integration (ASI) technique and its refined
version, the ASI-Gauss technique, has been developed to analyze various
dynamic problems of framed structures. It gives highly accurate solutions
with a minimum number of elements per member, by adaptively shifting the
numerical integration point in an element to a location where that of a
plastic hinge can be precisely expressed. The finite element code using
the technique drastically decreases memory resources and computational
time.
