Abstract:FE (finite element) modeling was conducted to 1) provide a better understanding of the
elastic behavior of the end region prior to cracking and 2) to evaluate the effects of bearing pad
stiffness and width on end region elastic stresses. The FEA (finite element analysis) program
Adina (R&D 2009) was used to conduct all modeling and analysis. All models were linear
elastic. Strain gage and displacement data from experimental work reported in Appendix B were
used to validate the FEA model. Hereafter the beams reported in Appendix B are referred to as
the “small beams.”
