STRUCTURAL BEHAVIOR OF A SKEW, REINFORCED CONCRETE, BOX GIRDER BRIDGE MODEL-VOLUME 1-DESIGN

A two-span, continuous, reinforced concrete, box girder bridge, with supports skewed 45 degrees, is to be modeled at a scale of 1:2,82, instrumented and tested at the University of California, Berkeley, to assess anomalies in structural behavior by comparison with previously observed behavior of a straight and curved models of the same scale, on orthogonal and radial supports, respectively. In particular, it is desirable to explore variations in support reactions from those observed for structures on normal supports and large diminutions in longitudineal girder resisting moments evidenced by analysis with a finite element program, called CELL, by means of which the model was designed. Methods used in the model design are described in detail in this preliminary report. As an example of the diminution of resisting moments noted above, this model design indicates a quantity of main longitudinal reinforcing bars (#4 bars simulating #11 bars in the prototype) about 81% of that used in the straight model on orthogonal supports. /FHWA/
