摘要

为了弥补既有Park-Ang双参数损伤模型计算工作量大，不便于实际应用，且易产生较大累积误差等方面不足，本文针对RC框架结构，基于构件位移损伤和耗能损伤关系，提出了一种基于层的半解析半数值双参数损伤模型，并通过与Park-Ang模型计算得到的层间损伤模式对比，验证了本文所提出模型的有效性。同时，得出以下结论：构件损伤由位移损伤和耗能损伤两部分组成，其中位移损伤起主要作用，且针对各层梁或柱，二者之间有较好的线性关系；RC框架梁、柱层间损伤模式与结构累积塑性变形能分配系数沿楼层的分布趋势相同。

Abstract

Existing two-parameter damage models are difficult for application because of the large calculation work quantity and tend to the more cumulative errors. Based on this, a semi-analytical and semi-numerical two-parameter model for RC frams is proposed, using the displacement damage and the energy one. Then the inter-story damage types calculed by the model proposed in this paper are compred with those obtained by Park-Ang model, and the feasibility of the proposed model is verified. At the same time, the following conclusions are obtained: the component damage is composed of the displacement damage which plays a major role and the energy one. And a good linear relationship exixtes between the two types of damage for RC columns and columns in each layer. Then the distribution of the inter-story damage betweenthe RC frame beam and the column is the same as the one of the cumulative-plastic deformation distribution coefficient along the layer.
