［摘要］大連國(guó)際會(huì)議中心15.30m標(biāo)高平臺(tái)周圈均為大懸挑結(jié)構(gòu)形式，各會(huì)議廳也主要采用大跨度鋼樓蓋，對(duì)人行激勵(lì)可能會(huì)非常敏感。而該建筑功能對(duì)舒適度的要求較高，所以需重視人行激勵(lì)下的樓蓋振動(dòng)問(wèn)題。本工程中較多地采用懸挑與大跨度的結(jié)構(gòu)形式，所以樓蓋的豎向振動(dòng)就成為比較重要的問(wèn)題。對(duì)結(jié)構(gòu)自振特性做了初算，并進(jìn)行了現(xiàn)場(chǎng)測(cè)試，根據(jù)現(xiàn)場(chǎng)測(cè)試結(jié)果調(diào)校模型，將加速度分析結(jié)果與實(shí)測(cè)結(jié)果進(jìn)行比對(duì)。列出了各分區(qū)的自振特性，根據(jù)各分區(qū)的功能情況進(jìn)行加速度分析，并將達(dá)沃斯會(huì)議廳隨機(jī)振動(dòng)分析的加速度情況和國(guó)際標(biāo)準(zhǔn)組織ISO的方法進(jìn)行了比較。

Abstract:The 15.30mplatforms of Dalian International-Conference Center are large cantilevered structures, and the meeting rooms are mainly large-span steel floors, which are sensitive to human excitation. Due to the high comfort performance requirement of the building, the floor vibration problem is important. In this project, long-cantilever and long-span structures are adopted much more, so the vertical vibration of the floor is an important problem. The structural vibration characteristics were analyzed and the field test was done.  Based on the test values, the model was adjusted and the acceleration results of analysis were compared with the test values.  The vibration characteristic of every part was introduced, the acceleration analyses of the parts were done, and the random vibration results of the DCC was compared with the method proposed by ISO.
Keywords:floor vibration；comfort；vibration characteristic；peak acceleration
