Secondary structure prediction of DNA is not as well established as for
RNA, but you may be able to use the same algorithms as RNA secondary
structure prediction programs by substituting in the free energy values
determined recently for DNA base stacking. As for DNA bending, I don't
think it is well enough understood to develop prediction algorithms.
There are experimental techniques available to determine the extent of DNA
bending, however. You might begin looking for papers by Richard Sinden or
Jan Klysik. I think they have done some work in this area.
