“…The self-vibration frequency under a dynamic load was higher than 15 Hz, which satisfied the requirements of domestic and foreign regulations [15]. The vibration performance and full-scale test data of bamboo composites for construction have not been reported, which limits their applications [16][17][18][19].…”

“…The bamboo bundles were joined from the width direction to form a bamboo bundle fibrillated veneer with a length of 300 mm by using a self-developed bamboo bundle veneer weaving machine. Then, samples were air-dried to a moisture content of 8-12%, and a bamboo bundle veneer with an average light transmittance < 10% and mechanical stiffness > 900 N mm-1 was selected [19] and marked as B for further use.…”

Bamboo engineering materials are green, high-strength, tough, durable, and structurally safe, and have promising application prospects in various modern green and low-carbon buildings. To invest the vibration behavior of new bamboo bundle veneer -laminated lumber (BLVL) for use in floor slabs, this study designed two kinds of full-scale vibration tests under a pedestrian load: an extraction hammer impact test, and a static concentrated load test, it is expected to provide theoretical and data support for the application of bamboo bundle veneer laminated composite materials in the construction field. The results showed that the self-oscillation frequency and mid-span deflection of the BLVL composite met the requirements of multiple relevant regulations when used as the structural material of floor slabs. The BLVL floor slab had a higher flexural stiffness and better vibration-damping performance than the OSB floor slab. The first-order self-oscillation frequency of the BLVL composite floor slab was 13.769 Hz, the damping ratio of the first three orders of modalities was 1.262–2.728%, and the maximum static deflection in the span of the joist was 0.932 mm under a 1 kN concentrated load. The 1 kN static deflection of the BLVL was reduced by 22.33%, and the root mean square (RMS) acceleration of the walking load response was significantly lower than that of the OSB floor slab. The preparation of BLVL composite materials by homogeneous lamination of bamboo bundle veneer and wood veneer may help improve the vibration behavior of bamboo-wood structures such as floor slabs and walls.

Sandwich panels’ exceptional mechanical properties and low density, owing to their multifunctional characteristics and innovative design, made them a popular choice in numerous industries. Sandwich panels with cellular cores are known for their exceptional energy absorption properties, which make them effective energy absorbers for high-impact scenarios such as accidents or explosions. For advancing research on sandwich panels, it is vital to develop innovative designs that can enhance their energy absorption and flexural stiffness. This review outlines the most essential topological parameters that influence the mechanical properties of cellular core structures. This paper gives insight into recent advancements related to optimizing sandwich panel structures for various engineering applications. The topological parameters investigated by researchers include core structure, thickness, number of layers, and material. The choice of core material governs the overall mechanical behavior of the panel. In this paper, various structures, including foam, honeycomb, lattice, corrugated, bioinspired, and various materials, are compared. Functionally graded structures were also explored in the literature as they can significantly optimize the response of sandwich panels in high and low-velocity impact applications. Similarly, a multi-layered core structure can enhance the total stiffness and specific energy absorption of the panel.
