“…The modelling also neglects the anisotropy of FRP composites. The predominance of tensile stresses, which are relatively low regarding the FRP strength [25], makes the assumed simplifications acceptable for the deformation analysis.…”

Stress-ribbon systems develop the most flexible and slender bridges. A structural system of such elegant bridges consists of cables or ribbons and deck slabs placed to these strips to distribute the live load. Although this structural system is simple, the design of such structures is a challenging issue. Design limitations of the bridge deck slope induce considerable forces in the ribbons, which transfer the tension to massive foundations. The deformation increase under concentrated and asymmetrical loads causes another problem of stress-ribbon bridges—the kinematic component, the design object of such structures, exceeds the dead load-induced vertical displacement several times. This paper introduces a new concept of such a structural system, comprising ribbons made of flexural-stiff profiles. The proposed approach to reduce kinematic displacements is illustrated experimentally by testing two pedestrian bridge prototypes with different flexural stiffness of the steel ribbons. Numerical models calibrated using the test results are used for the parametric analysis of the flexural stiffness effect on the deformation behaviour of the bridge system with steel and fibre-reinforced polymer (FRP) ribbons. A practical approach to the choice of the efficient flexural stiffness of the ribbon-profiles is also proposed.

“…In the model, the steel ribbons between the supports are simulated by the beam elements, and the ribbons on the saddle are simulated by the plate element. The beam element is adopted so that the bending stiffness of the ribbon, which is an important influencing factor [34], is taken into account.…”

There has been a noticeable rise in the construction of lightweight stress-ribbon pedestrian bridges. In regions with a high risk of seismic activity, it is crucial to employ advanced seismic control technology to mitigate the impact of earthquakes and improve the bridge’s performance and durability. The objective of this study is to investigate the effect of tuned mass dampers (TMDs) on a steel-plated stress-ribbon bridge using the finite element method. The study aims to analyze the performance of various TMD designs focusing on both vertical and torsional modes. Multiple TMD configurations are considered and numerically compared. The results indicate that TMDs offer both a tuning effect and a static mass effect for stress-ribbon bridges. The tuning effect is most pronounced when the mass ratio falls between 2% and 4%. Installing a single TMD with a mass ratio of 0.05 can decrease vertical displacement along the entire span by up to 36%. Furthermore, a torsional TMD effectively reduces both the torsion of stress ribbons and the pier forces. As a recommendation, the combination of a single vertical displacement TMD and a torsional TMD can be considered the most appropriate scheme for earthquake response control. Moreover, the addition of TMDs reduces the bridge’s sensitivity to the direction of earthquake excitation. These findings contribute to a broader understanding of the earthquake performance of stress-ribbon bridges and assist designers in selecting appropriate control schemes to address vibrational issues.

“…Axially loaded vertical element acting on a horizontally placed timber plate creates compression perpendicular to the grain and causes its displacement. In buildings with more than three storeys, an element loaded perpendicular to the grain finally undergoes immediate and long-term deformation (Leicester, Fordham, & Breitinger, 2011;Korin, 2011;Sandovic, Juozapaitis, & Gribniak, 2017). Two percent deformations were assumed and proposed in Basta, Gupta, Leichti, and Sinha (2012) to evaluate the limit values (in NDS -National Design Specifications) of stressing perpendicular to the grain.…”

This paper deals with the deformation characteristics of wood-framed residential, small commercial and hotel buildings with sheathing. Recent building structures are based on large panel or modular technology, where elements in the form of diaphragms or modules are constructed in an industrial plant and then transported to the site for assembly. The document presents diagrams of building assembly and technologies for realization. The significant influence of excessive vertical deformations in multistorey wood-framed buildings on their performance and serviceability is underlined. These deformations are caused by different factors which are identified and analytically described. The paper outlines the analytically complex model for the evaluation and control of deformations in the design, construction and exploitation of multistorey wood-framed buildings. An example of the application of the proposed analytical model at the design stage concludes the paper.
