# Pedestrian Comfort Analysis and Parameterized Optimization Design for Raised Floors
## 5 Conclusions  
The study aimed to enhance the pedestrian comfort of raised floors by proposing a novel parametric design optimization method. Through the integration of experimental modal analysis and theoretical modal analysis, carried out via finite element modeling, the first-order vertical natural frequency of the raised floors was effectively identified. A dynamic response analysis was subsequently employed to ascertain the peak acceleration at critical points during pedestrian activity. Based on these findings, the pedestrian comfort of the raised floors was quantitatively assessed, considering both the first-order vertical natural frequency and the peak acceleration at critical points.  
The principal conclusions drawn from this research are as follows:  
1. All four types of raised floors evaluated in this study satisfy the relevant criteria for pedestrian comfort. Comparative analysis reveals that incorporating an optimal quantity of EPS material into the raised floor significantly enhances pedestrian comfort.
2. In contrast to traditional evaluation standards, this study introduces a novel assessment that calculates the sensitivity of pedestrian comfort on raised floors with respect to pedestrians of varying weights, thereby broadening the evaluation criteria for pedestrian comfort.
3. The optimization design method proposed herein not only improves overall pedestrian comfort of the raised floors but also reduces the thickness of the support plates, thus achieving an equilibrium between pedestrian comfort and thermal performance. During the optimization process, correlation analysis unveiled the intrinsic relationships between characteristic variables and pedestrian comfort performance.
