早期混凝土由于水化反应都会产生体积变化.如果体积变形受到约束就会产生应力,一旦超过混凝土的抗拉强度就会产生裂缝.由于早期混凝土的力学性能是随时间变化的,特别是徐变,它不仅与加载时间有关而且同时随龄期而变化,因此计算早期混凝土结构应力是较为复杂的问题.有限单元法不仅可以考虑混凝土刚度的变化,而且可以考虑温度、徐变、收缩等因素.本文利用初应力法对通用有限元软件ansys进行了二次开发,通过工程实例计算了高层建筑地下室侧墙早期混凝土应力的变化过程,并提出了相应的抗裂措施 | | 6. | Creep analysis methods of high - rise buildings and large span buildings can only refer to creep coefficient method in bridge engineering or the method of degree of creep in hydraulic construction engineering under the present experiment conditions . in this paper , the incremental expressions of concrete creep and shrinkage strain when the initial computational age is not the same as the loading age are derived and corrected from the concept of concrete creep coefficient and the mean value theorem of integral and the principle of superposition . the differences of efficiency and accuracy of creep analysis between the finite element method with creep coefficient and the initial stress method with degree of creep are presented . this paper suggests that engineers should use the initial stress method with degree of creep to estimate the influences of creep on high - rise buildings and large span buildings on the basis of conceptual design
