The results showed that contact properties and gap size between tiles affected load-displacement relationship and strain of the TeSA beam. The pressure-overclosure relationship for contact properties and gap size were calibrated using the global load-displacement response obtained from testing. Incorporation of large deformations (geometric nonlinearity) in the analyses did not affect the results significantly. Beams with varying friction coefficient between tiles, load and support bearing width, Poisson's ratio and aspect ratios were also analyzed.
