摘要:
为了验证各种Park-Ang损伤指数修正模型能否对630 MPa级超高强钢筋混凝土柱的地震损伤进行准确评估。在配置630 MPa级高强钢筋的混凝土柱拟静力试验现象和实测数据的基础上,首先利用6种模型分别计算了8根典型试件的损伤指数,并与试验实测损伤指数范围进行了对比,分析了6种模型的适用性;然后在试验实测数据的基础上,对计算结果存在较大偏差的4种模型进行了参数拟合和模型修正。研究结果表明:Kunnath模型、Chai模型、修正的傅剑平模型、修正的王东升模型和修正的付国模型均能准确模拟630 MPa级高强钢筋柱的损伤指数发展规律,而修正后的Kumar模型计算结果反而偏小,效果较差。
Abstract:
In order to verify whether the various Park-Ang damage index correction models can accurately assess the seismic damage of concrete columns with 630 MPa high strength steel bar.Based on the phenomenon of quasi static test and the measured data of column with 630 MPa high strength steel bar the damage index of 8 typical specimens was calculated by using 6 models firstly, and the damage index was compared with the experimental range of damage index, and the applicability of 6 models was analyzed. Then the parameter fitting and model correction of the four models with large deviation in the calculation results were carried out based on the actual data. The results show that Kunnath model, Chai model, Fujianping model(modified), Wangdongsheng model(modified) and Fuguo model(modified) can accurately simulate the development of damage index of column with 630 MPa high strength steel bar, but the calculation results using the modified Kumar model are relatively small and the effect is poor.
