The values given in this table are based on hollow core slabs without shear reinforcement. Superscripts (1, 2, etc.) <br />following values in the table indicate the number of filled voids required at the ends of slabs to develop the allowable <br />superimposed load. See page 2, "SHEAR" for discussion. <br />2. Asterisk (*) following values in the table Indicate that the total deflection under all loads is greater than U360 but less <br />than U160. <br />3. interpolation between values is acceptable: Do not extrapolate values into the blank spaces of the table. <br />4. These Span -Load Tables are intended as an aid to preliminary sizing. Sound engineering judgement is required for <br />the application of this information to specific design cases. " <br />
