IMPACT ANALYSIS OF REINFORCED CONCRETE PANELS FOR WIND-BORNE MISSILES

摘要

USNRC Regulatory Guide 1.76, Design-Basis Tornado and Tornado Missiles for Nuclear Power Plants, identifies a set of missiles and impact velocities to be considered in the design of nuclear power plants. Empirical formulae have been used to calculate local and global responses of reinforced concrete walls and slabs impacted by tornado- and hurricane-borne missiles, where these formulae have been calibrated using a small set of test data. The empirical formulae are assessed for calculations of penetration depth, scabbing thickness, and perforation thickness using data from tests performed by EPRI and Calspan in the 1970s. Data from the tests were used to inform, and validate in part, LS-DYNA models. Lagrangian and Smooth Particle Hydrodynamic (SPH) formulations are used to predict penetration, scabbing and perforation. Limitations on the use of the methods are identified.
