本文提出了一种新的PARC_CL2.0裂纹模型，这是一种专为剪切敏感结构量身定做的RC模型。然后将该模型应用于SMART 2013试件的地震反应评估，该试件是在振动台上测试的钢筋混凝土核电站设施墙体结构，在强地震输入下进行了试验。研究的目的是从全局和局部响应的角度评估建模的预测能力，以部分填补大型结构非线性计算的需要和建模技术在实践中的适用性的空白。计算结果表明，该方法在顶层位移、楼层加速度谱、层间漂移和固有频率衰减等方面都能得到令人满意的结果。此外，使用壳单元的建模表明，计算成本保持在可接受的水平。
Presented in the paper is the new PARC_CL 2.0 crack model, a physical approach for RC modelling especially tailored to shear sensitive structures. The model is then applied for the seismic response assessment of the SMART 2013 specimen, a scaled RC nuclear power plants facility wall structure tested on a shaking table under strong seismic input. The aim of the research is to evaluate the predictive capacity of the modelling in terms of global and local response, in order to try to partially fill the gap for the need of non linear calculation for large structures and applicability of the modelling technique to the practice. The presented approach demonstrated to be able to provide satisfying results in terms of top displacement, floor acceleration spectra, interstorey drift and eigen frequency drop off. Moreover, the modelling using shell elements demonstrated to keep the amount of computational cost acceptable.
