Structural Screening and Evaluation Guideline

DOE-STD-3014-96

perforation - to prevent perforation, required wall thickness is 120 percent

of the predicted perforation thickness;

punching shear - to prevent punching shear failure, the predicted punching

shear stress should not exceed four times the square root of the

compressive strength of concrete (f'c) at the perimeter one-half the

effective depth away from the load, unless higher values can be justified

Local damage to steel targets:

penetration - to prevent perforation of a steel target, the minimum wall

thickness required is at least 125 percent of the predicted penetration

depth.

Excessive structural deformation or collapse:

for concrete structural components - permissible ductility ratios as

specified in American Concrete Institute (ACI) Code 349;

for steel structural components - permissible ductility ratios as specified in

section Q1.5.8 of American Institute of Steel Construction (AISC) Nuclear

Specifications, American National Standards Institute (ANSI) N690.

Structure, system, and component (SSC) functionality:

for evaluation by analysis - up to code allowable acceptance criteria given

in American Society of Civil Engineers (ASCE-4), American Society of

Mechanical Engineers (ASME) Boiler and Pressure Vessel Code, Institute

of Electrical and Electronic Engineers (IEEE)-344, and NUREG-0800, as

specified for safety-related SSCs;
