中文摘要 | 高層建築由於對耐震、材料輕量化及綠建築等要求標準日漸提升,許多高樓建築設計乃逐漸由傳統的鋼筋混凝土結構RC(Reinforced Concrete Constructure)改採鋼骨結構SC(Steel Constructure)或鋼骨鋼筋混凝土結構SRC(Steel Reinforced Concrete Constructure),此項構造轉變,加上高樓建築對停車位的高需求,一般大樓會將機械式停車塔與之共構,當停車塔運轉使用時,常造成大樓內之結構振動及傳音非常嚴重,此問題乃近年來建築界極待解決的項目。 本文應用類比測試及振動功率流之動性理論,來鑑定機械停車塔運轉時之振動功率流及結構音路徑,建立排序診斷方法,就最大振動功率流傳遞路徑提出 有效之隔振措施,利用隔振量頻譜預估結構音之改善量。本文方法就機座彈性對結構音防制有效度之影響 有獨特之考慮。 |
英文摘要 | Owing to the trend of requirements upgrade for antiearthquake material lightening and green construction utilization, most high-rise buildings are emerging to adopt steel construction (SC) or steel reinforced concrete (SRC) construction instead of the conventional reinforced concrete (RC) construction. In such change of construction material combined with the urgent needs of parking area, it is usually to install a solid mechanical parking tower in a high-rise building to save space. As a consequence, this building frequently results in a serious structure-borne noise and vibration problem during the operation of the parking machine. The article aims at the establishment of the ranking and diagnosis method to identify the sequence of vibration power flow and structure-borne noise transmission path during the system operation by employing the mobility theory and analogy testing. Once the maximum transmitted power flow and transmission path have been found, the amount of vibration isolation and the effective countermeasure of structure-borne noise control can be accordingly selected and designed. The established method has a unique part to take into the consideration of the influence of seating elasticity on the isolation effectiveness of vibration. |
