Re: How to apply cyclic load on shallow foundation in OpenSe

Hello. Thanks for replying. I have applied a pulse of 100000 cycles "timeseries pulse 1 0 100000 -factor 70". Is there anything regarding Rayleigh damping. ? I have not applied any Rayleigh damping.

How to apply cyclic load on shallow foundation in OpenSees?

A shallow foundation is modeled using BNWF model. but when a pulse time series(1 cycle/sec) is applied in vertical direction the displacement is constant after almost 1000 cycles. what can be done to find a plot between number of cycles versus settlement of shallow foundation????
