Shape-size optimization of single-layer barrel vaults using improved magnetic charged system search

In this paper, the problem of simultaneous shape an d size optimization of single-layer barrel vault fr ames which contains both of discrete and continuous variables is addres sed. In this method, the improved magnetic charged system search (IMCSS) is utilized as the optimization algorithm and the o pen application programming interface (OAPI) plays the role of interfacing analysis software with the programming language. A comparison between the results of the present metho d and some existing algorithms confirms the high ability of this approa ch in simultaneous shape and size optimization of t he practical and largescale spatial structures.
