“…For understanding the characteristics of TMDs and applying them effectively, they have been extensively studied from the 20th century 1 up to the present. [2][3][4][5] Previous studies have investigated the use of TMDs for controlling the response of buildings and civil structures to earthquakes. [6][7][8][9][10][11] The effectiveness of TMDs for reinforced concrete and steel high-rise buildings considering soil-structure interaction has been analyzed.…”

“…To allow for a comprehensive design of pedestrian bridges made of pultruded GFRP profiles, it is thus necessary to understand their dynamic properties compared with conventional materials, such as steel, which is the primary alternative material it aims at replacing. The high damping capacity of polymer‐based materials is well‐known (in some cases, higher than timber‐based structures 7 ) and widely used in the mechanical, automotive and aerospace industries. The vibrations produced in structures and mechanical components are the primary sources of damage in high‐precision instruments, machines, automobiles or aircraft.…”

Slender footbridges are prone to excessive vibrations due to pedestrian effects, and comfort criteria often govern their design. In this sense, composite materials that combine high damping capacity with relatively high stiffness and low mass can provide functional benefits. This paper presents a study of the dynamic behaviour of an 11 m long hybrid footbridge made of two I-shaped pultruded glass fibre reinforced polymer (GFRP) main girders and a thin steel fibre reinforced self-compacting concrete (SFRSCC) deck, in operation since 2015. The main goals were (i) to improve the knowledge of the dynamic properties of composite footbridges and (ii) to assess the benefits of using a structure made of pultruded GFRP instead of a conventional material (steel), namely, considering its greater ability to dissipate energy. The resonant frequencies, damping ratios, and mode shapes of the footbridge were identified based on experimental testing. A finite element (FE) model of the footbridge was developed and calibrated with test data and used to simulate the effects of pedestrian loads. Simulations of the same type were conducted on an equivalent structural system made of steel profiles. The simulation results of the two short-span footbridges with similar natural frequencies enhance the impact of high-order harmonics of the pedestrian load in the dynamic response. It is also shown that polymer-based components can contribute to limiting vibrations in footbridges or even act as self-dampers.

“…e method was further developed by Wang et al [8], concerning factors such as the aspect ratio of the floor, the number, and the walking speed of the occupants. To control the vibration of the CLT floor, Huang et al applied a multituned mass damper to reduce the floor vibration response [11,12]. In summary, the previous research on CLT floors have focused on the characteristics of the floors and vibration control measures.…”

The environment is one of the factors that may influence occupants’ perception of floor vibration and the assessment of floor serviceability. In this study, laboratory tests were conducted on a 3-ply CLT floor. Occupants’ assessment of the floor serviceability under human-induced vibration was investigated. Virtual reality (VR) technique was used as a research method, simulating two common environments in life. First, the correlation between the occupants’ annoyance rating and serviceability indicators (response factor and vibration dose value (VDV)) was compared with existing standards. The results show that the response factor method in ISO 10137:2007 is conservative for timber floors in both bedroom and gym environments. The VDV method in BS 6472-1:2008 can generally reflect the vibration acceptability of timber floor vibration. Then, the effect of acceleration and environment on the floor serviceability assessment was investigated through statistical methods, respectively. A weak positive correlation between the annoyance rating and the acceleration was found. The effect of the environment on floor vibration assessment was found to be significant.
