英文摘要
The dynamic stress amplification resulting from a sudden failure of a member has a considerable influence on a progress to the overall collapse. Therefore, this dynamic effect must be included in the conventional static redundancy analysis as an impact factor. The calculated values of the impact factor vary widely from member to member. However, the impact factors for critical members in the redundancy analysis take almost a constant value that ranges from 1.4 to 1.8. In order to predict approximately the magnitude of the member impact factors without carrying out the dynamic response analysis, a simplified method based on the RMS mode combination method is proposed. The accuracy of the member impact factors calculated by this simplified method is moderate.
