摘要:Abstract(#br)Under axial pressure or shear load, thin-walled plate and shell structures are easily destroyed by buckling. This paper presents the design method for finding the optimal stiffener layout on thin-walled plate and shell structures against the buckling by using th...

摘要:Abstract(#br)A multi-objective collaborative optimal design procedure for steel frames equipped with buckling-restrained braces (BRBs) is proposed under the framework of performance-based seismic design (PBSD) in order to minimize the damage of the primary structure as well as th...

摘要:Abstract(#br)This paper deals with two optimisation problems related to axisymmetric membrane shells made of homogeneous, linear and isotropic materials and subjected to an internal pressure. The design variables are the meridian shape and the thickness distribution (possibly not...

摘要:Abstract(#br)Hygro-thermo-chemical-mechanical models, used to determine the variations over time of temperature, relative humidity and shrinkage induced deformations in concrete components, are characterised by the presence of a large number of input parameters. Some of these par...

摘要:Abstract(#br)This paper proposes a new multi-fidelity bi-level optimization (MFBLO) strategy for shape designs of underwater wings. Firstly, hydrodynamic analyses of the wing planform and sections are decoupled for constructing a bi-level shape optimization frame, which includes ...

摘要:Abstract(#br)We propose an iterative separable augmented Lagrangian algorithm (SALA) for optimal structural design, with SALA being a subset of the alternating directions of multiplier method (ADMM)–type algorithms. Our algorithm solves a sequence of separable quadratic-like...

摘要:Abstract(#br)Reliability analysis accounting for only randomness of input variables often shows a significant error due to the lack of knowledge and insufficient data in the real world. Confidence of reliability indicates that the reliability has uncertainty caused by epistemic u...
