| 摘要: |
| 为研究“房桥合一”结构体系在多种动力荷载作用下高架站厅结构的舒适度与传统振动规范的适用性，对某大型客站进行人群、列车荷载下的动力测试，通过现场调查研究了该振动水平下的旅客烦恼反应；基于不同荷载类型与结构跨度，利用已有的考虑了模糊性与随机性的烦恼率模型进行反推计算，建立适合于评价“房桥合一”结构烦恼率的舒适度量化指标.研究结果表明：部分区域振动水平未达到人体感知阀值，实际烦恼率为2%；部分区域振动强度超过70 dB，其理论烦恼率为50%，然而实际烦恼率仍为2%，传统舒适度评价标准并不能准确评价该类新型结构体系.烦恼率模型可以量化任意振动强度下的干扰反应率，给出高架站厅结构的振动限值介于75~90 dB，与ISO规范振动反应描述较为一致，弥补了现行规范关于大跨度“房桥合一”结构舒适度评价的缺失.

| Abstract: |
| To study the comfort of "Building-Bridge Integration" station hall structure under various dynamic loads and the applicability of the existing vibration norms, a large passenger railway station was tested under pedestrian load and transit train load, meanwhile field investigation were implemented to study crowd disturbance response under the vibration level. This paper established comfort quantitative indicators, which is suitable to evaluate the annoyance rate of "Building-Bridge Integration" structure, based on different load styles and structure spans, used the existed annoyance rate model considering the fuzziness and randomness. Results indicate that partial region vibration level is under perception value, practical annoyance rate is 2%; partial region vibration intensity exceeds 70 dB, theory annoyance rate is 50%, but practical annoyance rate is 2%, traditional comfort evaluation standard can't accurately evaluate this structure type. Annoyance rate model can quantify annoyance rate under any vibration intensity, the vibration limit is between 75-90 dB, the result based on measured data is consistent with ISO standard in vibration response description, which make up deficiency of present comfort standard about long span"Building-Bridge Integration".
