I tried to simulate this attached research to study a new bolt under a moment connectionhttps://us.v-cdn.net/6032193/uploads/FAMVN16NZJ62/image.pngbut there some points I don't know how to apply them:1-"In finite element simulation of the column, the tube section was alienated into two zones, which are the flat and corner zones (seen in Fig. 7). According to Sully and Hancock [19], residual stress of 0.4fy and (0.24–0.0006B) fy can be applied for the corner zone and for the flat zone, respectively."https://us.v-cdn.net/6032193/uploads/PD9LZBMO9D2F/2.jpg2-"To simulate the loading condition a discrete rigid solid element was used to model the loading plate."3-"The base angles at the location of the bolts were also fully constrained by using Tie command in ANSYS."4-"In the first step, an axial load (N) with a constant rate was applied uniformly on the top surface of the columns and then a monotonic load to the tip of beams was applied."I have attached my model also.https://us.v-cdn.net/6032193/uploads/CDVHMF0ER8MY/i-beam-to-square-hollow-column-blind-bolted-moment-connection-experimental-and-numerical-study.wbpzhttps://us.v-cdn.net/6032193/uploads/AFJD5UDNADJ2/i-beam-to-square-hollow-column-blind-bolted-moment-connection-experimental-and-numerical-study.pdfhttps://forum.ansys.com/discussion/23134/how-to-simulate-hss-to-i-beam-boltet-connection
