［摘要］大跨度空間結(jié)構(gòu)樓蓋的人行舒適度問(wèn)題是結(jié)構(gòu)設(shè)計(jì)中不可忽視的重要因素。在對(duì)結(jié)構(gòu)舒適度使用性能的評(píng)價(jià)方法和評(píng)價(jià)標(biāo)準(zhǔn)總結(jié)歸納的基礎(chǔ)上，提出了通過(guò)分析樓蓋結(jié)構(gòu)的振動(dòng)特性，如最小自振頻率、振動(dòng)峰值加速度等，來(lái)控制樓蓋結(jié)構(gòu)的剛度，作為結(jié)構(gòu)舒適度設(shè)計(jì)依據(jù)的方法。設(shè)計(jì)方法成功應(yīng)用于財(cái)富中心的大跨度懸吊樓蓋結(jié)構(gòu)設(shè)計(jì)，并結(jié)合回廊第1階的自振頻率及模態(tài)的工程實(shí)測(cè)結(jié)果，驗(yàn)證了分析方法的可靠性。

Abstract:The vibration comfort design of large-span floor is an important issue of structure design. Based on the summarization of evaluation method and criterion of vibration comfort performance, the vibration comfort design method of adjusting the stiffness of floor through analyzing its vibration behavior was proposed. The method was successfully used in the structure design of the suspended floor of Prosper Center, and it was also proved to be reliable through experiment.

Keywords:suspended floor; vibration comfort; vibration frequency; peak acceleration; vibration detection
