To cover large areas without the use of intermediate columns or with the use of a small number of intermediate columns, space structures are commonly used. Light weight, elegant appearance, fast development, and ease of erection are all important characteristics of these structures. Barrel vaults are a type of latticed space structure that is arched in only one direction. The dynamic response of square-on-square offset steel barrel vault structures with various angles of curvature and depths is the focus of the analysis. The dynamic responses of the analytical model in the X, Y, and Z directions when exposed to a horizontal earthquake are investigated. Linear dynamic analysis (time history analysis) is carried out using SAP 2000 V22 program to examine the performance of the barrel vault during seismic loading. The barrel vault model with a 90° open angle generated the most efficient results for horizontal ground motions, according to the results.
