Key pipe profile properties that influence the performance of the soil/pipestructure interaction include the moment of inertia of the profile (I), distancefrom the inside diameter to the neutral axis (c), and the section area of alongitudinal profile section (As). Pipe stiffness (PS) is also important criteria.The minimum pipe stiffness, defined by AASHTO was used for this analysis.These key properties are summarized in Table 12.section property summarynominalinsidediameter(IN)outsidediameter(IN)pipestiffness,PS (PSI)crosssectionalarea, as(in ˆ 2/in)distancefrominsidediameter toneautralaxis, c (in)moment ofinertia, I(in ˆ 4/in)pitch(IN)4.0 4.7 50 0.076 0.14 0.0012 0.656.0 6.9 50 0.122 0.19 0.0037 0.788.0 9.1 50 0.146 0.28 0.0085 0.9710.0 11.4 50 0.180 0.33 0.0171 1.2912.0 14.3 50 0.183 0.47 0.0366 1.9415.0 17.5 42 0.222 0.51 0.0549 2.5918.0 20.8 40 0.244 0.58 0.0824 3.1024.0 27.5 34 0.330 0.72 0.1593 3.1030.0 34.6 28 0.370 0.95 0.3118 3.8836.0 41.5 22 0.410 1.12 0.4986 5.1742.0 47.4 20 0.448 1.18 0.5531 5.1748.0 53.8 18 0.498 1.21 0.6551 5.1760.0 66.7 14 0.660 1.44 1.2766 7.76Table 12Note: Section property data is considered conservative, however, propertiesmay change based on actual production dimensions.5.5 Construction and Paving Equipment LoadsEAGLE CORR PE INSTALLATION GUIDE55
