Hello, Corrosion and insufficient reinforcement clamping or overlapping length multipliers on the curtains are left at 0 and 0.4, respectively. Take these values as 1. If necessary, enter a value between 0 and 1 depending on your system. (item 7.2.3 for corrosion and 7.4.14 for insufficient reinforcement clamping or overlapping length) When performing performance analysis, take the structural importance factor as 1, not 1.5. (item 7.4.2) Good work...
