STANDARD 1: STANDOFF DISTANCES PARAMETERS. Figures B-1 and B-2 have many Qualifications (PAGE 1/2). building structure must meet Conventional Construction Parameters to use the conventional construction standoff distances provided in these tables If the building structure does not meet Conventional Construction Parameters OR if there is not adequate standoff distance, then the structure needs specific analysis or hardening for blast effects at the available standoff distance Windows and doors must be designed for the applicable standoff distance Windows and doors need to be properly anchored to the supporting structure The structures around the window and door openings need to be designed for the increased applied loads due to larger tributary areas to the adjacent supporting elements 13 14.

CCP are fairly well How are we supposed to determine what is the defined for exterior best Standoff Distance for our building ? walls unless you have very tall walls How can we quickly get the window and door Roof systems are supplier to give us a quote? very limited. Most commonly used roof What glazing size and type will work best for our systems will need to project? be designed for blast pressure. 15 16. THE SOLUTION: DESIGN aids STANDOFF DISTANCES.

UFC 4-010-01, Conventional Construction Standoff Distance Those tradeoffs will generally need to be analyzed when standoff distances are less than 82 feet (25 meters) for Explosive Weight I. and 33 feet (10 meters ) for Explosive Weight II. There are tools in UFC 4-020-01 that can assist in evaluating those tradeoffs.
