Cyclic load on shallow foundation

Post by sasmalsk » Mon Aug 21, 2017 11:34 pm

A shallow foundation is modeled using beams on non winkler foundation model. first gravity load is applied and analysis is done . then the cyclic load on foundation is applied as follows. what extra can be done/what corrections to be made to find a plot between number of cycles of load vs settlement of shallow foundation?

loadConst -time 0.0
timeSeries Pulse 1 0 100000 1 -factor 71.8;
pattern Plain 2 1 {
load 1 0.0 -1.0 0.0
}
