This article presents an evolutionary topology optimization method for compliance minimization of structures under design-dependent pressure loads. In traditional density based methods, intermediate values densities the solid elements arise along iterations. Extra boundary parametrization schemes are demanded when these methods applied to loading problems. An alternative methodology is suggested in this handling type load. With extended bi-directional structural associated with a partially...
Black-box topology optimization (BBTO) uses evolutionary algorithms and other soft computing techniques to generate near-optimal topologies of mechanical structures. Although are widely used compensate the limited applicability conventional gradient techniques, methods based on BBTO have been criticized due numerous drawbacks. In this article, we discuss as a black-box problem. We review main methods, their challenges present approaches relax them. Dealing with those effectively can lead...
This paper presents an evolutionary structural topology optimization method for the design of completely submerged buoyant modules with design-dependent fluid pressure loading. type structure is used to support offshore rig installation and pipeline transportation at all water depths. The proposed seeks identify buoy that has highest stiffness, allowing it withstand deepwater pressure, uses least material a minimum prescribed buoyancy. Laplace's equation simulate underwater polymer buoyancy...

Abstract Glued laminated timber (glulam) beams manufactured with glued steel bars can achieve improvements in their mechanical performance and the effects of arrangement cross-section are technological interest. This study aimed to evaluate behavior symmetric reinforcements (compression tension zones) asymmetric zone), under loading imposed at serviceability limit state. To this goal, glulam reinforcement ratios ranging from 0.5% 4% were simulated using finite element method. When compared...
Glued-Laminated Timber (GLULAM) is a widely-used building material, popular for its strength, durability, and sustainability. It created by bonding together layers of wood, making it common choice civil structures. In this study, Bi-directional Evolutionary Structural Optimization (BESO) proposed to improve the performance GLULAM By positioning steel bars within structure, objective increase structure's stiffness enhance structural integrity. To achieve this, study introduces concept...
