TOPOLOGY OPTIMIZATION OF PERFORATED STEEL PLATE SHEAR WALLS WITH THICK PLATE IN SIMPLE FRAMES
In this paper, topology optimization (TO) is applied to determine the form, size and location of holes for the special form of perforated steel plate shear wall (PSPSW). The proposed model is based on the recently presented particular form of PSPSW that is called the ring-shaped steel plate shear wall. The strain energy is selected as the objective function in the optimization. Simple Isotropic...
متن کاملTopology and Parametric Optimization of a Lattice Composite Fuselage Structure
Conventional commercial aircraft fuselages use all-aluminium semi-monocoque structures where the skin carries the external loads, the internal fuselage pressurization and is strengthen using frames and stringers. Environmental and economic issues force aircraft designers to minimize weight and costs to keep air transport competitive and safe. But as metal designs have reached a high degree of p...
متن کاملTopology Optimization of Composite Structure Using Bi-Directional Evolutionary Structural Optimization Method
This paper deals with topology optimization of composite structure using Bi-directional Evolutional Structural Optimization (BESO) method. By redefining the criteria of the optimization evolution progress, the proposed method is able to extend current BESO method from isotropic material to anisotropic composite material. The initial modification of BESO method is to allow for inefficient Materi...
متن کاملTopology optimization of planar cross-sections
1 I n t r o d u c t i o n Historically, structural component design has been a complex blend of experience, intuition, and heuristics. The advent of computers has fostered the widespread use ofmore rigorous optimization techniques for both conceptual and detailed phases of design. Structural optimization efforts generally are classified in thr~e categories: (1) size optimization, which allows v...
متن کاملElastic Buckling Analysis of Composite Shells with Elliptical Cross-section under Axial Compression
In the present research, the elastic buckling of composite cross-ply elliptical cylindrical shells under axial compression is studied through finite element approach. The formulation is based on shear deformation theory and the serendipity quadrilateral eight-node element is used to study the elastic behavior of elliptical cylindrical shells. The strain-displacement relations are accurately acc...
