Popis: Abstract The purpose of the present study was to investigate the effect of the geometric arrangement of the trusses on the response modification factor of the special truss moment frame. For this purpose, six different geometric arrangements for the three types of trusses (Vierendeel, multiple Vierendeel panels, and X-diagonals) were considered. The results were obtained based on non-linear static analysis of two- and three-span frames for 4- and 8-story structures with the given geometric arrangements. According to the results obtained, different truss arrangements can affect the response modification factor by about 4 to 10%. Additionally, using multiple Vierendeel panels and the X-diagonals can increase the response modification factor by 1.06 and 1.74 times, respectively. Article Highlights 1. Different truss arrangements do not have a significant effect on the coefficient of behavior. 2. The addition of several Vierendeel panels does not have much effect on the behavior of these structures. 3. Adding cross diameters almost doubles the coefficient of behavior and significantly improves the performance of the structure.
