Abstract

In this research, the evaluation of progressive damage due to fire in high-rise steel structures with diverging braces has been done. For this purpose, a frame with two openings and one floor has been selected from the reference article, and the fire scenario was implemented in one of the openings, and the horizontal displacement of the middle of the structure and the top of the column with the displacement values obtained from the reference article, comparison and accuracy. was measured In the continuation of the research, 24 samples were analyzed in 3 categories. There are 15 floors in the first category of samples, 20 floors in the second category of samples, and 25 floors in the third category of samples. In each category, the first 4 samples are without braces and the second 4 samples are with divergent braces. In each category, the fire scenario was in the middle column of the first floor in the first sample, in the side column of the first floor in the second sample, in the middle column of the middle floor in the third sample, and in the side column of the middle floor in the fourth sample. The samples were subjected to static load and fire in the desired column, and the following results were obtained from this research.
