Abstract
A new finite element code using the Adaptively Shifted Integration (ASI) technique with a linear Timoshenko beam element, which can express member fracture by a plastic hinge located at an exact position with a simultaneous release of the resultant forces in the element, is applied to the seismic damage analysis of reinforced concrete (RC) framed structures. Contact between members is also considered in order to obtain results that agree more closely with actual behaviors such as intermediate-layer failure. By using the proposed code, sufficiently reliable solutions have been obtained and the results reveal that this technique can be used in the numerical estimation of structural reliabilities.
