Fatigue Assessment of Panaro Bridge
In this paper, preliminary studies performed on the Italian case study, the Panaro Bridge, are reported. In particular, results of the standard fatigue assessment according to Eurocode rules were compared with the actual fatigue damages occurred to deck secondary components to obtain a preliminary critical review of adopted fatigue assessment methodologies.
Strength Improvement to Composite T-Joints under Bending through Bio-inspired Design
This paper shows that a bio-inspired design methodology is an effective method to strengthen composite T-joints under bending loading, whose ply angles were tailored using an optimisation program mimicking the evolutionary process of adaptive growth.
Prestress optimization of hybrid tensile structures
This paper deals with cable domes design and study the role of the cable prestress and of the prestress optimization. In particular it is shown how, for a generic spatial truss, a suitable cable pretensioning makes us able to assign a geometrical stiffness to the whole structure and, in this way, to improve its overall behavior.
Exploring the potential of climate adaptive building shells
Building shells with adaptive, intuitively offer opportunities for both energy savings and comfort enhancements. Development in this field is still fragmented and the most effective type of climate adaptive building shell (CABS) behaviour is still unknown. This paper explores the potential of CABS by using building performance simulation in combination with multi-objective optimization.
Integrating automatic zone modeling with GA for structural optimization of a composite wing
This work by Embraer and ITA is intended to present a two-step methodology for the structural optimization of a preliminary composite wing based on automatic zone modelling strategy followed by GA iterations.
Multi-objective Optimization of an America's Cup Class Yacht Bulb
modeFRONTIER genetic algorithms were used to define the best possible configuration of an America's Cup class yacht bulb, considering two different objectives and integrating multiple simulation tools, in order to obtain the minimum drag and the lowest center of gravity.
CPP propeller cavitation and noise optimization at different pitches with panel code
In the present paper a multi-objective optimization, carried out in the framework of EU funded project SILENV—Ship-oriented Innovative solutions to reduce Noise & Vibrations, of an existing CPP propeller for a RO–RO ferry is presented.
Efficient Global Optimization Applied to Design and Knowledge Discovery of Supersonic Wing
Efficient global optimization (EGO) was applied to the multi-objective design and knowledge discovery of a supersonic transport (SST) wing. In particular, modeFRONTIER is used for the visualization of multidimensional data. modeFRONTIER creates a map in a 2D hexagonal grid, which can be colored based on the every attribute values (for the design variables, and the objective functions).
Automated design and fabrication of micro-air vehicles
A methodology for an automated design and fabrication of micro-air vehicles (MAVs) is presented. A design optimization framework has been developed that interfaces several software systems to generate MAVs to optimally fulfil specific mission requirements. By means of a multi-objective genetic algorithm, families of MAVs are tailored with respect to objectives such as weight and endurance.
A New Method to Preliminary Design Structural Components
The aim of the hot structure design process is to ensure the structural integrity of the component minimizing two fundamental parameters: mass and thickness. The former influences the total weight of the vehicle, the latter influences the vehicle efficiency.
