Hello,
TO model a shear key in bridge abutment I have to define a trilinear link in F2 direction, but the third stifness is negative to take acount for the break in shear keys after a defined force limit. Which link type I should use???

I have the same problem how can i send my model? and if you can say what were the errors in mortezarazi's
model so i can myself fix them in mine?
thanks

<r>1-I am modeling a 8 story rc frame in seismostruct and etabs. etabs calculates 1st period as 1.76 but sesimostruct gives only 0.65. <br/>
2-I am using diaphragm constraints for each story but for a 2d 8 storis model why should it found 10!!!! modes?????<br/>
where can i upload my file to get help ...
