摘要：

This paper presents a stochastic investigation of an impacted reinforced concrete structure. A generalized form is proposed to represent the constitutive surfaces of concrete, i.e. the yield surface and strength surface. A genetic algorithm is used to evaluate the parameters that define the constitutive surfaces. A transient dynamic finite element compute engine is used to simulate the response of a reinforced concrete structure being hit by a projectile. The direct localization pinball approach is used to model the impact mechanics. Sensitivity studies and probabilistic evaluations of structure impacted by a projectile are performed and time dependent compliance probability evaluated.
