Deformation Analysis of Saw-tooth Building Structure Under Seismic Actions

The saw-tooth mill building with skylight window frames as supporting structures is a special bent. This type of building has many advantages. Although it is widely used, its behavior under seismic actions has not been thoroughly understood. Based on the study of three different experiments on a saw-tooth structure, displacement characteristics under horizontal earthquake force and the weaker position for the displacement of saw-tooth structure are discussed. A computer programme to calculate the load-displacement curve and the value of ultimate deformation are developed. At the same time, a simplified method to estimate the deformation capacity of saw-tooth structure for designer is proposed in this paper.
