Thanks!

Thanks a lot

can one element use different sections？

thanks

Does the 3d corotational transformation consider ele loads in current release--version 2.2.0？
thanks

It seems that concrete fiber number have little influence on the results. Maybe this is because that the reinforcement number is about 200 in section.

About 180 dispbeamcolumn elements, and 700 fibers and 10 integration points in section

a high-pier bridge
this problem appears when I use more fibers or more elements.

following warning is the same?
UmfpackGenLinSOE::UmfpackGenLinSOE:ran out of memory for A and colA with nnz = 109693
What sre A , colA, nnz?

what does this mean?Thanks

Thanks a lot
Do you mean the Figure 30.Steel02 material--Material Parameters of Monotonic Envelop, Figure 31 and Figure 32?

in time-history analysis I use steel02 material, its stress-strain results confuse me, time stress strain 11.7 4.24237e+008 0.0200587 11.72 4.25554e+008 0.0207169 11.74 4.26111e+008 0.0209953 11.76 3.90718e+008 0.0208177 11.78 2.83493e+008 0.0202544 11.8 1.43052e+008 0.0193889 11.82 -3.58221e+006 0....

Can I call the displacement history resulted from transiant analysis as the residual displacement?
Sorry I am cofused by displacement and residual displacement.

the residual displacement is the displacement which is not zero?

The example apple the Sine UniformExcitation--accelaration time history, then how to apply Sine nodal load to some node?
