Abstract: In structural optimization problems, conventional approximations are often used. For this type of approximations, move limits are usually defined as allowable changes in design variables during optimization of the approximate ...

Abstract: Assuming force method analysis formulation, the effect of compatibility conditions on optimal design of trusses is studied. Neglecting the latter conditions, a linear programming (LP) formulation is obtained. The possibility ...

Abstract: Topological design, where the member connectivity is sought in addition to member sizing, is perhaps the most challenging and economically the most rewarding of the structural optimization tasks. ...

Abstract: Some aspects of analysis and design of protective structures are discussed. It is demonstrated that parametric analyses can be used to obtain an approximate model for reanalysis. The latter describes the major phenomena ...

Abstract: The combined approximations approach, developed originally for linear static reanalysis, is used for dynamic reanalysis of structures. The approach is based on the integration of several concepts and methods, including ...
