Scope

This practice is intended to standardize the minimum structural design loading for underground precast concrete utility structures.

The user shall verify the anticipated field conditions and requirements with design loads greater than those specified in this standard.

1.1 This practice describes the minimum live loads and dead loads to be applied when designing monolithic or sectional precast concrete utility structures. Concrete pipe, box culverts, and material covered in Specification C478 are excluded from this practice.

Note 18212;For additional information see AASHTO Standard Specification for Highway Bridges, Seventeenth Edition.

Note 28212;The purchaser is cautioned that he must properly correlate the anticipated loading conditions and the field requirements with the design loads used.

1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
