High all.
There are many books and article which specified spring stiffness for single, mat and also strip foundation for modeling and calculating revised period and damping considering SSI ( Soil structure interaction seismic effects on structure seismic demands) , but i have seen nothing how to do this for grid foundation. would you please advise me :
1-How I can calculate grid foundation springs?
2- Are there any reference?
3- i want to model the effect of SSI in some "equipment supporting structures in petrochemical plant which has RC frame and grid foundation".
thanks in adnavce
