The Adaptively Shifted Integration (ASI) technique with a linear Timoshenko beam element, which can express a plastic hinge located at an exact position by shifting the numerical integration point, is implemented into a seismic collapse analysis code of reinforced concrete (RC) framed structures. Static and dynamic numerical tests are carried out to verify the proposed code as well as the Degrading tri-linear type model for an RC member, which is also implemented into the code. A contact algorithm is added in order to obtain results that agree more closely with actual behaviors such as mid-story failure. By using the developed code, sufficiently reliable solutions have been obtained and the results reveal that this code can be used in the numerical estimation of seismic design of RC framed structures.
