Damage States Investigation of Infilled Frame Structure Based on Meso Modeling Approach

The non-linear behavior of infilled frames is very complex. this structure may be studied by experimental and numerical approaches. An test can provide a more realistic output but has the disadvantages high costs, relatively long time specific room usage. A analysis an alternative to analyze frames. One most powerful approaches meso-modeling. This approach advantage being able capture local damage panel. For reason, progressive identified in meso-model used as basis for determining state criteria. grouping states proposed based on initial identification form linked global damage, i.e., IDR. study’s level frame DS1 = 0.17%, DS2 0.52%, DS3 0.79% DS4 1.99%. However, quantification results structural cannot generalized because many complex factors influence Subsequently, parametric study was carried out determine contribution mechanical properties material degree damage.
