摘要：
Existing two-parameter damage models are difficult for application due to a large amount of calculations and more cumulative errors. Here, a semi-analytical and semi-numerical two-parameter model for RC frams was proposed based on displacement damage and energy one. Then the inter-story damage modes calculated with the proposed model were compared with those obtained with Park-Ang model, and the feasibility of the proposed model was verified. The results showed that component damage is composed of displacement damage which plays a major role and energy one; a good linear relationship exists between the two types of damage for RC beams or columns in each layer; the distribution trend of the inter-story damage between a RC frame's beams and columns is the same as that of its cumulative-plastic deformation energy distribution coefficient along layers. © 2016, Editorial Office of Journal of Vibration and Shock.
