1. DESIGN AND IMPLEMENTATION OF FLC APPLIED TO A SMART GREENHOUSE
ABSTRACT Greenhouse cultivation needs an accurate modelling and an optimised control system to ensure an adequate microclimatic condition for plants. It represents a complex task due to the high number of input factors. For this reason, an improved intermediate modelling was established under the platform of the MATLAB/Simulink environment to simulate the en

2. Modelagem da transferência de calor de ambientes subterrâneos no programa de simulação EnergyPlus
Resumo A temperatura do solo é um dos fatores mais influentes nas avaliações de desempenho térmico de ambientes subterrâneos e quase sempre é desconsiderada. Por isso, é necessário avaliar essa influência devido à interação do solo com a edificação, pois a transferência de calor através de paredes e pisos subterrâneos tem uma extensão signi

3. XFEM Modelling in Multi-bolted Joints Using a Unified Bolt Preload
Abstract Multi-bolted joints are adopted and designed to provide efficient load transfer within assembled engineering parts. Bearing failure is favorable during design phase due to more progressive failure mode, however, ability of by-pass stress to be transferred to adjacent bolts in multi-bolted joints prone to catastrophic net-tension failure. Former appr

4. Modelling the Hot Flow Behaviors of AZ80 Alloy by BP-ANN and the Applications in Accuracy Improvement of Computations
Hot compressions of as-cast AZ80 magnesium alloy in a wide temperature range of 523-673 K and strain rate range of 0.01-10 s–1 with a height reduction of 60% were conducted by a Gleeble-1500 thermo-mechanical test simulator. The hot flow behaviors show highly non-linear intrinsic relationships with temperature, strain and strain rate. In order to model the

5. Computational Modelling of RC Slabs Cracking with an Embedded Discontinuity Formulation
Abstract This paper investigates the cracking process of reinforced concrete slabs subjected to vertical load, involving their crack pattern and the load-displacement capacity curve. Concrete was discretized with hexahedral finite elements with embedded discontinuities; whereas steel reinforcement was represented by 3D bar elements, placed along the edges of

6. Numerical study of concrete-filled steel composite (CFSC) stub columns with steel stiffeners
Numerical study of concrete-filled steel composite (CFSC) stub columns with steel stiffeners is presented in this paper. The behaviour of the columns is examined by the use of the finite element software LUSAS. Results from nonlinear finite element analyses are compared with those from corresponding experimental tests which uncover the reasonable accuracy of

7. Analysis of the stresses in corrugated sheets under bending
This paper presents three different numerical models for the evaluation of the stresses in corrugated sheets under bending. Regarding the numerical simulations different approaches can be considered, i.e., a elastic linear analysis or a physical nonlinear analysis, that considers criteria to fail for the sheet material. Moreover, the construction of the fini

8. Compressive stress-strain behaviour of cement mortar-composites reinforced with short sisal fibre
To design building elements using sisal fibre reinforced mortar composites, the stress-strain curves of the composites both under tensile and compression load is needed. In this study short sisal fibre-cement based composites were developed and their stress-strain behaviour under compression characterized experimentally. The composites consisted of two morta

9. Behaviour of stiffened concrete-filled steel composite (CFSC) stub columns
This paper investigates the behaviour of axially loaded stiffened concrete-filled steel composite (CFSC) stub columns using the finite element software LUSAS. Modelling accuracy is established by comparing results of the nonlinear analysis and the experimental test. The CFSC stub columns are extensively developed using different special arrangements, number,

10. Rutting prediction of asphalt mixtures modified by polypropylene fibers via repeated creep testing by utilising genetic programming
A novel application of genetic programming (GP) for modelling and presenting closed form solutions to the rutting prediction for polypropylene (PP) modified asphalt mixtures is investigated. Various PP fibers have been utilised for bitumen modification and repeated creep (RC) tests have been carried out. Marshall specimens, fabricated with multifilament 3 mm
