The concrete modulus of dowel sup-port also seems to vary with the width of the dowel (Ref. 4 and 5). Fortunately, the concrete modulus of dowel support value is relatively insensitive to the analy-sis and need only be approximate; we have chosen a value of 1,500,000 pounds per cubic inch. This value is what was used in Reference 4 for all ...

Modulus of dowel support K 0 increases with increased concrete strength (fc ′), decreases with increased concrete depth below the dowel, and decreases with increased dowel bar diameter. Yoder and Witczak found that K 0 ranges between 300,000 and 1.5 million pci (8,303.972 and 41,519.858 kg/cm 3 ).

The purpose of this research is to determine the modulus of dowel support, Ko, for the steel elliptical and round epoxy-coated dowel bars. Once Ko is determined it will be used to determine the concrete bearing stress at the face of the joint, b. Once the bearing stress is known the dowel bars can be compared to determine which type of

Loss of support is treated in the design procedure by reducing the composite modulus of subgrade reaction. Figure 301-1 lists the LS factors to be used for ODOT materials.
