ANALYSIS OF BRIDGE PROOF-LOAD DATA. II. NUMERICAL RESULTS

Results from the proof-load testing of 1202 bays of 51 reinforced and prestressed concrete bridges are statistically analyzed in order to: (1) quantify the bias of standard theoretical deflection predictions, (2) compare the behavior of bridges with different deck types, spans, and end-constraints, (3) decompose the total variation of the elastic modulus into various terms (variation from construction company to construction company, from bridge to bridge, and from bay to bay), and (4) analyze the spatial dependence of the bay-to-bay variation term. The numerical results are presented here, whereas the main modeling and statistical analysis issues are addressed in a companion paper. (TRRL)
