摘要：	The main objective of this study was to assess live load e?ects on eight cast-in-place (CIP) reinforced concrete (RC) box culverts by conducting field load tests. Understanding the actual response of the culverts will provide insight as to how the live loads are actually distributed as well as the actual rigidity of the box corner connections. More precisely, the research e?ort goals were to: (1) study the current standard DOTD culvert drawings and the inspection reports for the eight selected culverts, (2) define critical sections and produce culvert specific instrumentation plans, (3) instrument the culvert by installing the sensors at specified locations and evaluate the current condition, (4) conduct the live load test and collect sensor data, (5) build FE models for each culvert and calibrate them using collected sensor data, (6) load rate the selected culverts for design and legal trucks, and (7) provide the rating details and recommendations to assist rating of CIP-RC box culverts.
