In the paper, most suitable probability distributions for SCFmax in DKT-Joints stiffened with FRP under axial loading conditions are studied. To this end, 1296 models were generated and then analyzed ANSYS to provide five reliable samples. Created FE validated using previous laboratory data. Afterward, predict appropriate distribution models, 12 different kinds of utilized check fit curve Next, accuracy reliability curves assessed help goodness-of-fit tests, such as Kolmogorov-Smirnov (KS)...
The stress concentration factors (SCFs) in uniplanar fibre-reinforced polymer (FRP) DKT joints are calculated under five axial loading conditions to determine the maximum SCFs. To this end, 108 finite element models of reinforced with different FRPs and geometrical parameters analysed. Available experimental data formulas used validate models. validated utilized investigate effects FRP along on joints. simulations show a reduction SCF by around 40% compared unreinforced effect increases...
With growing concerns about the danger of global climate change and worldwide demand for energy, interest in investigation construction renewable energy technologies has increased. Fixed platforms are a type support structure wind turbines composed different types tubular joints. These structures under kinds cyclic loadings ocean environmental conditions, which must be designed reinforced against fatigue. In present paper, relationships between parameters DKT-joints with FRP axial loads...
An assessment is made of the stress distribution and hydrodynamic response preliminary structural design tension leg platform a 10 MW wind turbine. The supporting turbine modelled analysed by finite element method. determined in still water with at above-rated conditions, estimated time domain. results domain analysis show reasonable agreement between present available data. To check stiffener dimensions, span, spacing against distribution, classification societies’ recommendations are used....
Numerous offshore wave energy converter (WEC) designs have been invented; however, none has achieved full commercialization so far. The primary obstacle impeding WEC is the elevated levelized cost of (LCOE). Consequently, there exists a pressing need to innovate and swiftly diminish LCOE. A critical challenge faced by WECs their susceptibility extreme loads during storms. Promising concepts must demonstrate robust design features ensure resilience in adverse conditions, while maintaining...
The objective of present research was the derivation probability density functions (PDFs) for degree bending (DoB) in tubular KT-joints commonly found jacket-type platforms. A total 243 finite element (FE) analyses were carried out on 81 FE models subjected to three types in-plane (IPB) moment loading. Generated validated using experimental data, previous results, and available parametric equations. Based results study, a sample database prepared DoB values histograms generated respective...
