ULTIMATE LOAD TESTS OF CONTINUOUS, COMPOSITE BRIDGE MODELS

The results of ultimate load tests of two models of continuous span slab-girder bridge structures are presented. These tests were intended to provide data for checking a computer program for inelastic behavior of continuous bridges. Of the models tested, one had two spans, the other had three spans and both models consisted of three equally spaced steel "S" beams supporting a poured concrete slab. It was concluded that the computer program provides an excellent means of predicting the behavior of continuous, composite highway bridges. In addition, it was found that the effective widths and load distribution factors at inelastic loads differed from the corresponding elastic values, and that elastic distribution factors for negative moment are different than those for positive moment.
