Study on the influence of non‐load effects during the whole process of construction of setback super‐tall structures
The mechanical characteristics of the setback super‐tall structure are complex, and the design is difficult. In the actual analysis and design process, the relevant influencing factors should be fully considered. In this paper, the fine construction simulation analysis of the super‐tall structure is...

| description | The mechanical characteristics of the setback super‐tall structure are complex, and the design is difficult. In the actual analysis and design process, the relevant influencing factors should be fully considered. In this paper, the fine construction simulation analysis of the super‐tall structure is carried out. Based on the shrinkage test of concrete members, the CEB‐FIP 90 shrinkage model is modified in terms of the parameters of cross‐section shape and size. The modified model is used to calculate the shrinkage strain of concrete, and the influence of uneven settlement of foundation and seasonal temperature on the structure is considered in the construction simulation analysis. The influence proportion of each non‐load effect on the horizontal displacement, vertical displacement, and internal force of key components is obtained. The refined construction analysis results are compared with the field monitoring data, and the data are in good agreement. |
