Nonlinear dynamic analysis of wind turbine towers subject to design wind and seismic loads
… more reliable designs, especially in the case of ultimate loading of horizontal axis wind turbines. The approach is highly nonlinear, and requires advanced numerical techniques to achieve accurate solutions. The programming of these techniques is achieved using the Embarcadero's Delphi, which is a …

Slab-on-girder prestressed concrete bridges: linear and nonlinear finite element analysis and experimental load tests
… bridge were performed in order to predict its ultimate capacity. Two bridge configurations were analyzed. The first one was modeled without any diaphragms or edge stiffeners, while the second one with end diaphragms and edge stiffeners. Ultimate loading results show that AASHTO LRFD presents …

Numerical and Experimental Investigations on Static Behaviour of Composite Cold-Formed Steel and Timber Flooring System
… tested composite specimens, improvements in the ultimate loading capacity and stiffness were found as a result of the mobilisation of composite action. A three-dimensional (3D) finite element model was developed in ANSYS software and validated against the experimental results. The validated …

Foot Deformity and Bone Strength in Charcot Neuropathic Osteoarthropathy
… metatarsals, as well as an ex vivo validation of ultimate loading strength using cadaver samples. Results in Aim 1 showed that BMD and indices of compressive, bending, and buckling strength were strong correlates of metatarsal ultimate strength. Aim 2 provides group comparisons of vQCT-derived …

Numerical and physical modelling of piled rafts on soft clay under combined loading
… combinations of vertical, lateral, and moment loading, under cyclic and seismic conditions. Examples of structures commonly founded on piled rafts include, e.g., high-rise buildings, bridge piers and wind turbines on weak soils, where the possibility of high differential settlements or the lack …

Effect of concrete heterogeneity on FRP-to-concrete bond behaviour
… When the switch of failure mode happens, the ultimate loading capacity of the FRP-to-concrete bonded joint is improved significantly.<br/>To more realistically model the meso-mechanical processes and the effect of concrete heterogeneity, a 3D mesoscale method and its application in the 3D …

Stochastic analysis of structures made of composite materials
A probabilistic methodology for the reliability analysis of composite rotor blades at the ply level was developed. The proposed methodology involves (i) the quantification of the uncertainties (physical, statistical and model) related to the material properties and the extreme aero-elastic loads …
