When doing P-Delta analysis for the design, what does the message "Load Case = 101 Convergence Error (SRSS) = 3.6603E-02 INCH" in the output file mean?

 "Load Case = 101 Convergence Error (SRSS) = 3.6603E-02 INCH" is NOT an error message. It is a measure of the convergence tolerance. If are getting a lot of these messages and you don't want to see so many of them you can set your tolerance to a lower value, say, 1/4 ". This can be done by adding "SET DISP 0.25" into the std file, provided the units has been set to inches.
