### A Seismic Collapse Analysis Code for Framed Structures using ASI-Gauss Technique

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. In this presentation, capabilities of the numerical code in seismic response
analyses are shown by comparing the results with detailed numerical simulations
performed by the parallel finite element analysis code, the E-Simulator
and experimental results obtained by the full-scale shake-table test using
the world’s largest shaking table, the E-Defense.
