［摘要］建筑使用過程中人員活動引起的樓蓋振動舒適度評估是建筑品質(zhì)設(shè)計(jì)的重要方面，其本質(zhì)為結(jié)構(gòu)動力學(xué)分析設(shè)計(jì)內(nèi)容。樓蓋的舒適度不僅與結(jié)構(gòu)本身的質(zhì)量和剛度特性有關(guān)，還與不同的人員激勵類型及評價標(biāo)準(zhǔn)有關(guān)。某大跨度樓蓋項(xiàng)目在建筑功能上存在人員的行走、跑動、跳躍和跳舞等各種不同的活動類型，同時結(jié)構(gòu)輕質(zhì)且布置較為復(fù)雜，樓板的振動問題得到了各方的重視。通過研究樓板振動分析和設(shè)計(jì)的方法、條件和標(biāo)準(zhǔn)等，對整體和不同功能區(qū)域的樓板進(jìn)行了系統(tǒng)的分析研究以指導(dǎo)深化設(shè)計(jì)，其技術(shù)和經(jīng)驗(yàn)可供類似工程設(shè)計(jì)參考。

Abstract:Assessment of floor vibration caused by human activities during is an important aspect of building quality design, which is the content of structural dynamics analysis. The serviceability of the floor is not only related to the quality and stiffness of the structure itself, but also to different types of human motivation and evaluation criteria. There are various types of human activities of walking, running, jumping and dancing in the building function of a large-span floor project, and at the same time it features light structure and complex layout. The vibration problem of floor has gotten the attention of the parties. Through the study of methods, the conditions and standards for floor vibration analysis and design, systematic analysis and study were conducted on the overall and different functional areas of the floor to guide the deepening design, and its technology and experience can provide reference for similar engineering design.
Keywords:human reduced vibration analysis; large span floor system; walking excitation; running excitation; jumping excitation; crowding excitation; serviceability
