主　　题：RC column scaled disance blast load LS-DYNA 

摘      要：Reinforced concretes(RC)have been widely used in *** construction,one of the eritical elements carrying a high percentage of the weight is columns which were not used 1o design to absorb large dynamic load like surface *** study focuses on investigating blast load parameters to design of RC columns to withstand blast *** numerical model is based on finite element amalysis using *** results are validated against blast feld tests available in the *** of simulations are performed with changing blast parameters *** efects of various scaled distances on the nonlinear bchavior of RC *** to simulation results,the scaled distance has a substantial infuence on the blast response of RC *** lower scaled distance,higher peak pressure and larger pressure impulse are applied on the RC ***,keeping the scaled disance unchanged,increasing the charge weight or shorter standoff distance cause more damage to the RC *** studies are carried out to investigate the efects of scaled distance and charge weight on the damage degree and residual axial load carrying capacity of RC columns with various column width,longitudinal reinforcement ratio and concrete *** of this research will be used to asessmsent the efet of an explosion on the dynamic behavior of RC columns.
