A Study of the Damage Estimation Method Based on Monitoring Data of High-rise Steel Buildings

Abstract

This study is about the damage ratio of the fatigue design. The problem of buildings damaged by earthquake has been considered significantly, especially the cumulative damage caused by the long-period ground motion. Recently, building research institutes have designed a new criteria on component cumulative damage. Thanks to the development of the monitoring technology, it is possible to find the cumulative damage ratio that not only exists in the inter-story drift angle but also in the component cumulative damage which is found by dealing with the data appropriately. However, the study has focused on how to continue using the buildings damaged by earthquake.

Besides, by collecting monitoring data, we conduct research on studying building damage condition accurately and quickly. Then it claims that this method is precise when applying the frame model and simple MDOF model.
