“…To avoid the reduction of living comfort caused by overly soft glulam oors, Reinforcing Ribs Wood Beams (RRTB) are typically installed underneath the wooden oors to improve overall stiffness and meet the requirements of building codes. Because wood structure oors are anisotropic (Zhou et al 2021;Brémaud et al 2011; ; Titirla et al 2020), the vibration characteristics of glulam oors can be easily affected by the size of the beams, which in turn can impact residential comfort (Ding et al 2020). Indeed, it is surprising that there is a scarcity of paper speci cally addressing the impact of RRTB on the vibration comfort of oors.…”

This paper presents the dynamic characteristics of the glued-laminated-timber (glulam) oor in China's tallest wooden o ce building and establishes a Finite Element (FE) model. The FE model's applicability is veri ed through experiments. The study investigates the effect of Reinforced Ribbed Wood Beams (RRTB) on oor vibration characteristics and evaluates the comfort index. Ambient Vibration Test (AVT) and human walking tests was carried out on the speci c oor. The results show that the RRTB signi cantly increase the overall stiffness of the oor, and change the natural frequency and modal vibration shape of the oor. The thickness of the RRTB has a more signi cant effect on the dynamic characteristics of the oor compared to its width. The static de ection of the oor is the most sensitive to the size change of the reinforced ribs, compared to the fundamental frequency and maximum displacement. For high-rise glulam building oors, AVT can be effectively applied to fundamental frequency testing; Even if the fundamental frequency of the oor meets the comfort index, acceleration and velocity amplitude tests are still necessary.

“…The beams of this panel are the parts that are connected with the vertical elements of the structure (columns, facades, etc.). In this study, the panel is investigated for two connection types (see detail 1 of Figure 1), as the connection's stiffness can vary [4,18]. In addition, the case study examines the effects of the porous material on the floor of the panel in order to damp the vibroacoustic response of the structure (see detail 2 of Figure 1).…”

This research aims to investigate the impact of incorporating porous materials on reducing noise and vibration in wooden floor panels, and to analyze the vibroacoustic performance of the assembled panel under different types of excitation and boundary conditions, particularly in the lower frequency range. The study begins with an experimental investigation and numerical modeling to determine the mechanical properties of the orthotropic wood material used in the floor panels. Subsequently, a finite element formulation, based on a variational approach, is presented to study the vibroacoustic response of an elastic structure coupled with a porous material exhibiting realistic behavior. The porous material is characterized by two phases: solid and fluid, represented in the formulation through the displacement field for the solid phase and the pressure for the fluid phase. This formulation offers the advantage of reduced computation cost and simplifies the coupling between all domains. To calculate the acoustic radiation of the structure, the Rayleigh integral is employed. Utilizing the proposed numerical approach, a comprehensive study is conducted to analyze the reduction in vibration–acoustic response of the floor with the incorporated porous layer, taking into account different types of excitation and boundary conditions applied to the system.

“…The beams of the panels are the part that is being connected with the columns of the structures. The stiffness of these connections can varies as it depends on the type of the connection as Titirla et al have been presented [20][21][22][23], but in this study only the case of a rigid connection was presented.…”

The present work concerns the dynamic and vibroacoustic response of timber floor panels as well as the study of the effect of material nonlinearities and damping. Each panel is composed of glued laminated beams and wood constituting the floor. The dimensions of the panels are defined to ensure appropriate implementation and transport conditions. For these reasons, the width of the panels is fixed at 2.40 m, and the length is 7.2 m. Two types of floor panels were investigated with and without struts. A numerical approach based on 3D finite element method is used to solve the problem. Our finite element model and the mechanical properties of the used materials are first validated from comparisons with experimental tests carried out in statics [1]. A dynamic non-linear analysis of the timber floor panels has been then conducted under a walking time history and the vibroacoustic response of the system is finally investigated.
