Coefficients for a Calculation of Section Force in Several Culverts

Abstract

At present, various analysis techniques are adopted for the structural design of culverts as hydraulic structures. The coefficient values for calculating the section force for culvert cross sections were calculated by the FEM using beam elements, and in this report, those are tabulated.
In the circular cross section of culverts which is shown in the design standard of Agricultural Structure Improvement Bureau, Ministry of Agriculture, Forestry and Fishery, the calculated cross section is shown definitely, therefore, by using this cross section, the validity of the calculation technique was checked up. Thereafter, as for the other types of culvert cross section, the demand of which is paticularly large in the design field, the coefficient values were calculated and tabulated. Further, when the section force is calculated, the condition of calculation at the time of using the coefficient values was shown clearly, and description was made also on the matters to which attention should be paid at the time of the use.
