Substructuring strategy for pseudo-dynamic testing of steel lattice towers
Other titre : Growing with youth / Croître avec les jeunes
(2019)
Abstract: Lattice towers are the most commonly used structures in the field of overhead power transmission lines. In the design process of transmission lines, there are several methods for the evaluation of their capacity. ...
Modeling multilayered wire strands, a strategy based on 3D finite element beam-to-beam contacts - Part II: Application to wind-induced vibration and fatigue analysis of overhead conductors
(2017)
Abstract: Wind-induced loads cause electrical transmission line fatigue. Evaluation procedures consider descriptors such as deflection amplitude (Yb) and far-field vibration (fymax), which cannot relate endurance limits ...
Experimental investigation of multi-material aluminum-to-steel and GFRP-to-steel bonded and bolted/bonded connections
(2016)
Abstract : Through an experimental study, this paper describes the behavior of single-lap bonded, bolted and bolted/bonded connections for configurations with minimum geometric parameters proposed in design references. Two ...
Effect of geometric parameters on the behavior of bolted GFRP pultruded plates
(2016)
Abstract : This paper presents the effect of geometric parameters on the behavior of bolted GFRP pultruded plates for civil engineering applications. After a literature review, results of an experimental analysis investigating ...
Experimental study of dynamic bending stiffness of ACSR overhead conductors
(2015)
Abstract : Aeolian vibrations of transmission line conductors may cause fretting fatigue failure at or near the location of clamped devices. At these locations, the bending stiffness variation of the conductor has a large ...
Effect of geometrical parameters of aluminum-to-steel bolted connections
(2015)
Abstract : Through experimental and numerical studies, this research work aims to provide directions on the optimal geometric configuration for single-lap and double-lap bolted connection between aluminum alloy 6061-T6 and ...
Strengthening of the net section of steel elements under tensile loads with bonded CFRP strips
(2014)
Abstract : The use of CFRP is increasingly common as a solution for the strengthening of structures, but the majority of research and applications have focused on the retrofit of concrete structures. The application of ...
Numerical analysis of ACSR conductor-clamp systems undergoing wind-induced cyclic loads
(2018)
Abstract—Submitted to wind induced vibrations, overhead
conductors are vulnerable to fatigue damage, especially at
restraining fixtures such as the suspension clamp. This paper
proposes an efficient finite element ...
Assessment of the effect of residual stresses on the mechanical behavior of steel lattice transmission towers
Other titre : Building tomorrow’s society / Bâtir la société de demain
(2018)
Abstract: Power transmission lines predominantly involve lattice towers, which are typically composed of steel angle members connected together by means of bolted joints. An effective design of such structures requires the ...
Resistance and failure modes of cold-formed lipped angle subjected to tensile load
Other titre : Building tomorrow’s society / Bâtir la société de demain
(2018)
Abstract: Cold-formed steel angles could be an advantageous alterative to hot rolled steel angle for the application of light-weight electrical transmission towers. However, standard design equations to evaluate the ...
