“…Under the same load, the slip value in the static load stage before the test is less than that in the static load stage after 10,000 overload fatigue loads. On the other hand, under the action of repeated load, the concrete near the stud will increase the void displacement between the stud and the concrete, resulting in the total slip amount of static load after 10,000 fatigue cycles under the same load is greater than the slip amount of static load before the test, which also indicates that the test beam has accumulated damage after the overlimit fatigue load [17,18]. 4(a)).…”

In this study, a model of test beam in negative moment area is designed, and the slip characteristics of test beam under overlimit static load and variable amplitude cyclic load are studied, respectively. By constructing the relationship between shear stiffness and slip parameters of the test beam, the deformation calculation method of the test beam under different fatigue cycles is derived, and the accuracy of the calculation model is verified by experiments. The results show that the maximum slip value (0.038 mm) of static load after 10,000 times of limited fatigue load is increased by 58.3% compared with that before overlimit fatigue load is applied (0.024 mm). When the fatigue cycle is 0-2 million times, the total slip is between 0.019 and 0.026 mm and the residual slip percentage is between 4.17 and 8.33%. The maximum residual values are 0.022 mm, 0.027 mm, and 0.028 mm after 1.5 times, 2 times, and 3 times of overload and variable amplitude fatigue loads, respectively, and the slip values have no obvious fluctuation, all of which show good working performance. The average value of the ratio between the deformation value and the measured value of composite beams is 0.89, and the standard deviation is 4.86%. When the fatigue loading times are more than 2.8 million, the ratio between the calculated value and the measured value is less than 0.85, so the adaptability of the calculation model has certain limitations. On the whole, the calculation model proposed in this study fully considers the factors such as the stiffness and fatigue loading times of composite beams, and the error between the calculated results and the measured results is within 5%, with high accuracy, which can be used as a reference for the actual design.

“…with different approaches pursued for representation of the interlayer behaviour. The most common approaches are those that utilise contact or interface elements and those that utilise solid elements [25][26][27][28][29][30][31]. Some few studies assumed a perfect bond/composite action between the faces [34], however such assumption is not valid for most timber-concrete sandwich panels and thus those approaches are not discussed further in this paper.…”

“…[9][10][11][12] Specific applications have been proposed for composite shafts, 13,14 thinwalled laminated box beams, 15 and reinforced concrete structures. 16 Although curved members can be simply discretised by a sequence of short straight beams, [17][18][19] a considerably large number of elements are needed just to capture the displacements correctly. Furthermore, regardless of the mesh density, straight beam elements typically miss the stress variation within the cross section that is associated with a strong curvature of the axis.…”

This paper presents the closed-form formulation for a three-dimensional curved beam element with round bimaterial section. The formulation includes the effects of shear forces on displacements and stresses and of the beam curvature on the distribution of bending and torsional stress over the cross section. The element is coherent with the well-known theory for straight beams, which is obtained exactly as the curvature radius becomes infinite. The numerical predictions for a test case compare favourably with published analytical and experimental results and with the outcome of a purposely developed, large-scale FE brick model
