PDelta problem
Dear Mr.Silvia, thank you for replying me yestoday and I got a new problem. I performed 2 set of time history analysis for a 9story building with 6 different ground motions. 1st set is with PDelta effect and the 2rd set without PDelta effect, but the results of the 2sets are almost the same. Error o...

Problem due to gravity load
Dear Mr. Silvia. I have a simple problem. It's SDOF subjected to a gravity load and a ground motion. When the gravity load is applied, the results will be completely wrong (lateral displacement is 100times lower than the correct result), while when the gravity load is removed the results are closed ...
