Induced by unusual events such as people gatherings or furniture stacking, extraordinary loads rarely occur but can exhibit significant amplitudes. Though, sufficient statistical data are required to quantify the stochastic behavior of loads, traditional surveys typically depend on manual on-site questionnaires, leading low efficiency, occupant resistance and problematic weight estimation. In this study, multi-source online therefore used propose a new survey method. Object weights obtained...
The vibration serviceability of an as-built long-span concrete floor was assessed using field measurements taken during the structure's daily use and under controlled human activities including a group people walking jumping at specific frequencies. serves as waiting hall railway station has unique external prestressing system. measured natural frequencies recorded accelerations were compared with threshold values specified in design guidelines. fundamental frequency estimated to be...
Developing a model for the dynamic force generated by pedestrian’s foot on supporting structure (single footfall trace model) is crucial to advanced numerical analysis and vibration serviceability assessment of structure. A reliable needs reflect inter-subject intra-subject randomness human walking. This paper introduces stochastic single in form Fourier series which body weight, walking frequency, first eight harmonics are treated as random variables. An experiment used 73 test subjects, at...
Dozens of human-induced load models for individual walking and jumping have been proposed in the past decades by researchers are recommended various design guidelines. These differ from each other terms function orders, coefficients, phase angles. When designing structures subjected to loads, many cases, a model is subjectively selected engineer. The effects different on prediction structural responses efficiency vibration control devices such as tuned mass damper, however, not clear. This...
Abstract Strong earthquake disasters can cause noticeable damage correlations among regional buildings with similar mechanical properties, termed structure‐to‐structure seismic correlation, which has a pronounced impact on the risk assessment and therefore needs to be properly quantified. This study first introduces time‐domain analytical equivalent frequency‐domain analysis based random vibration theory for calculating correlation coefficients. Subsequently, by employing spatially...
In this study, Ground penetrating radar is used to detect the quality of back-filled grouting in a shield tunnel. A simulated GPR record shows that steel bars lining segments usually generate strong scattering and multiples, thereby obscuring reflections from objects making it difficult locate objects. Various filtering methods for multiple suppression (i.e., predictive deconvolution, f-k attenuation, Karhunen-Loeve transformation) were applied typical defect model. The `wave field...
