| 摘 要： | CEB-FIP90和CEB-FIP78模型分别是我国新、老桥梁规范所采用的徐变预测模型。这里结合算例从模型结构、环境相对湿度、混凝土理论厚度、加载龄期等7个方面对两个模型进行了对比,分析表明CEB-FIP90模型更多地考虑了徐变的非线性本质,其预测值在多数情况下小于CEB-FIP78模型。

| Abstract: | Combined with the sampling,the two prediction models of concrete creep are compared and analyzed from the aspects,such as the model structure,the relative humidity of the ambient environment,the notional size of the member and the age of the concrete at loading.Results from analysis indicate that the non-(linear) behaviors of the concrete creep are more considered in the CEB-FIP90 model and the predication values are usually less than those from the CEB-FIP78 model in most cases. |
