Here is a few papers dealing with ff96 (I am sure there's more), in
particular check Ono et al that specifically discusses the propensity of
ff96 to form extended structures:
Kamiya N, Higo J, Nakamura H. Conformational transition states of a
beta-hairpin peptide between the ordered and disordered conformations in
explicit water. Protein Science 2002;11(10):2297-2307.
Higo J, Ito N, Kuroda M, Ono S, Nakajima N, Nakamura H. Energy landscape
of a peptide consisting of alpha-helix, 3(10)-helix, beta-turn,
beta-hairpin, and other disordered conformations. Protein Science
2001;10(6):1160-1171.
Ono S, Nakajima N, Higo J, Nakamura H. Peptide free-energy profile is
strongly dependent on the force field: Comparison of C96 and AMBER95. J
Comput Chem 2000;21(9):748-762.
Wang L, Duan Y, Shortle R, Imperiali B, Kollman PA. Study of the
stability and unfolding mechanism of BBA1 by molecular dynamics
simulations at different temperatures. Protein Science 1999;8(6):1292-1304.
