Abstract: While most airfield pavements are periodically evaluated to determine their structural capacity, often little thought is given to the structural capacity of the culverts and other drainage structures beneath the pavement. The Department of Defense has never had a standard means of evaluating box culverts under airfields or landing strips This capacity has been needed on several occasions, particularly overseas where landing strips are sometimes built into the local highway system. The research reported herein evaluated several different methods for performing the structural evaluntion of reinforced concrete box culverts under aircraft loads, selected two computer programs (CANDE-1980 and CORTCUL) for detailed testing, and then developed a culvert evaluation methodology based on the CORTCUL program. To assist in determining the aircraft loads , an additional computer program was developed. This program, CULVERT, uses elastic layer theory and predefined aircraft data to calculate the vertical stress acting on the top of the culvert due to the aircraft and also provides output and plotting capabilities . Stress is then applied to the culvert model along with the member loads, soil loads, and other loads such as internal water. The CORTCUL program evaluates the culvert based on the requirements of ACI 318, "Building Code Requirements for Reinforced Concrete."
