Wind Analysis of Tall-Reinforced Concrete Chimney Considering the Effect of Soil–Structure Interaction
The dynamic interactions between tall chimney, underlying foundation, and the elastic soil beneath are the focus of this paper’s thorough assessment. This collaboration, known as soil–structure interaction (SSI), is based on the interactions between the features of the chimney and the soil. For tall-reinforced concrete chimneys subjected to wind loads, soil–structure interaction (SSI) analysis is being carried considering the Raft foundation. Based on various material characteristics, three types of soil are taken into consideration in order to comprehend the significance of SSI. Chimneys of different elevations are selected for the parametric study. The raft thickness is being varied. Wind analysis is carried out in accordance with IS: 4998:2015, and the wind speed taken into account during the analysis is 55 m/s. The along-wind force and across-wind force is being calculated in the study. Three-dimensional finite element tool ABAQUS is used for the analysis based on the direct method of SSI. The lateral deflection and base moment of the tall chimney are evaluated through SSI analysis and compared with the response obtained from chimney with fixed base. Base moment decreases significantly with effect of SSI. Performance of chimney considerably depends upon the material characteristics of chimney, foundation and soil. When we considered the effect of SSI as height increases lateral deflection also increases due to flexibility of soil compared to fixed condition.
