“…During this period, they are subjected to different environmental conditions. In addition, as indicated in reference [28], there is a direct relationship between temperature changes and the modulus of elasticity of a composite material. Therefore, an advanced measuring system was used to assess the influence of atmospheric effects on the behavior of the full-size pedestrian bridge span.…”

2020

View full text Add to dashboard Cite

The paper presents application of different sensors for the purpose of short and long term measurements, as well as a structural health monitoring (SHM) system to assess the behavior of a novel fiber reinforced plastics (FRP) composite footbridge. The aim is to present a thorough and concise description of these sensors networks and results gathered with their aid during in situ measurement of strains, displacements, and vibrations, as only a few works are available in this field. The bridge geometry, material solutions, and properties are described at first. Then the measurement devices composing the system and subsystems of sensors are elaborated on. Subsequently, the bridge research program is described and the results are shown and discussed. Finally, it is concluded that the use of selected sensors is helpful in assessment of the behavior of the novel structure, and moreover in validation of its numerical models. The collected data confirmed many assumptions made during the bridge design process and allowed us to accept it for exploitation.

“…Quasi-static ±45 • off-axis tension/compression tests were investigated in [7][8][9][10][11][12][13][14][15] on various FRP composite materials with thermoset or thermoplastic matrices at different crosshead displacement ratios [4]. Only short-term displacement-controlled processes were examined.…”

This study presents an experimental investigation of an in-plane shear of a glass lamina composite using a ±45° off-axis tension test. Typically, the shear stress curve, shear modulus, and in-plane shear strength for composite lamina-type materials are identified. Previous research indicated that a loading rate affects the strength of this composite. This study extends the existing literature by utilising a non-contact optical digital image correlation (DIC) method to measure strain distribution during the test. Two cross-head displacement rates were examined. The obtained strain maps reveal an uneven distribution resembling fabric texture. As the deformation progresses, the differences in the strain pattern increase. Subsequently, a quantitative analysis of the differences between regions with extreme (minimum and maximum) strain values and regions with average values was conducted. Based on these measurements, shear stress–strain curves, indicating variations in their courses, were constructed. These differences may reach several percent and may influence the analysis of numerical simulations. The DIC results were validated using strain gauge measurements, a commonly utilised method in this test. It was demonstrated that the location of the strain gauge installation impacts the results. During the tests, the occurrence of multiple microcracks in the resin was observed, which can contribute to the nonlinearity observed in the shear stress–shear strain curve.

“…В [16,17] механические свойства стекловолокон сравнили со свойствами других волокон, а также с помощью динамического механического анализатора исследовали вязкоупругие свойства эпоксидного композита с E-стекловолокнами и трех гибридных эпоксидных композитов (с волокнами S-и Е-стекла; углеродными; органическими и E-стеклянными). Механические свойства композитов, армированных стекловолокном, изучали также в [18][19][20][21] и установили, что их свойства в значительной степени зависят от толщины волокон, их ориентации [22], концентрации [23] и природы [24].…”

Слоистые композиты с разной укладкой S-стекловолокон изготовили методом литьевого прессования с вакуумной инфузией смолы и изучили их механические свойства. Оценили влияние типа укладки и угла несоосности армирующих волокон на прочность композитов при растяжении, изгибе, межслойном сдвиге и прочность при смятии болтовых соединений. Результаты показали, что прочность при растяжении и изгибе однонаправленных стеклопластиков более чувствительна к углу несоосности, чем ортогонально армированных [0°/90°].
