Frontiers of Structural and Civil Engineering 2020, Volume 14, Issue 6,   Pages 1531-1544 doi: 10.1007/s11709-020-0675-7

Abstract: the current models that adopt two damage variables, the independence of these damage variables during cyclicloading results in the failure to capture the effects of tensile damage on the compressive behaviorThis study presents a cyclic model established by extending an existing monotonic constitutive model.The model describes the cyclic behavior of concrete under multiaxial loading conditions and considersmultiaxial loading conditions including uniaxial tension and confined compression.

Joint slip investigation based on finite element modelling verified by experimental results on wind turbine lattice towers

Saleh YAGHOOBI, Ahmad SHOOSHTARI

Frontiers of Structural and Civil Engineering 2018, Volume 12, Issue 3,   Pages 341-351 doi: 10.1007/s11709-017-0393-y

Abstract:

Slippage corresponds to the relative displacement of a bolted joint subjected to shear loads since the construction clearance between the bolt shank and the bolthole at assembly can cause joint slip. Deflections of towers with joint slippage effects is up to 1.9 times greater than the displacements obtained by linear analytical methods. In this study, 8 different types of joints are modelled and studied in the finite element program, and the results are verified by the experimental results which have been done in the laboratory. Moreover, several types of joints have been modelled and studied and load-deformation curves have also been presented. Finally, joint slip data for different types of angles, bolt diameter and bolt arrangements are generated. Thereupon, damping ratios (z) for different types of connections are reported. The study can be useful to help in designing of wind turbine towers with a higher level of accuracy and safety.
