Abstract:

DIAL PACK Event of the MIDDLE NORTH Series, Bell Laboratories Project LN-318, involved the evaluation of the blast-induced response of the SA Manhole. The SA Manhole was a full-size, segmented, precast-concrete hardened structure, to be used by the Long Lines Department of American Telephone and Telegraph Company, to house electronic repeater equipment. Testing was designed to determine the extent of cracking, equipment environments, and overall structural response. Author
