A Pre-engineered steel building (PEB) has become one of the most efficient & simplified building type in the steel construction industry use of tapered members for columns and rafter is one of the basic property of PEB. Use of web tapered member increase the efficiency of PEB. The connection between the tapered member is the crucial factor which decide the efficiency of structure tapered with decide of research, semi-rigid beam to column connections have been widely accepted. It is very interesting to study the effect of semi-rigid connections of the tapered member like PEB during the pushover analysis of structure. The different level of rigidity of joints may changes the behavior of capacity & demand curve of pushover analysis. The variation of results may alter the different values of damage indices, Response reduction factor and even vulnerability assessment factor. So here in the present study, the attempt is being make to study the effect of different levels of rigidity factor of a joint for PEB structure, the aim of the present work is to investigate the different value of Response reduction factor for varying the rigidity levels of a joint of PEB. The pushover analysis (non-linear static analysis) is going to perform for the structure, the performance point is likely to be study for all developed models. The response reduction factor values are mostly given by IS 1893: 2016 Part-I for generalized structure without mentioning the types of connections. So here the attempt is being made to calculate their value by Newmark Hall method as per existing literatures. Lastly the comparison of R Factors is done for all the developed models. From the entire study it is observed that the more value of rigidity of a joint provide more value of response reduction factor. The performance point of capacity & demand curve as per ACT 40 shows much erratic for lesser values of rigidity factors of PEB connections.
