摘要: 首先介紹了國內(nèi)外樓蓋舒適度的評價標準. 而后依據(jù)《建筑樓蓋結(jié)構(gòu)振動舒適度技術(shù)標準》 ( JGJ/ T 441—2019) ,對北航青島校區(qū)圖書館懸掛報告廳的吊板的舒適度進行設(shè)計,采用 MIDAS Gen 軟件對懸掛報告廳進行舒適度數(shù)值模擬分析,包括建模參數(shù)取值、吊板基頻確定、局部模型正確性驗證、荷載工況及計算結(jié)果分析. 最后對吊板舒適度設(shè)計的關(guān)鍵控制參數(shù)進行了分析. 結(jié)果表明,局部模型可取包括吊柱、吊板、吊梁及相鄰一跨結(jié)構(gòu)的模型. 應(yīng)以局部模型為基準,通過掃頻的方法確定吊板的基頻. 在進行舒適度設(shè)計時,應(yīng)首先保證吊梁的剛度,再調(diào)整吊板的厚度及邊梁剛度,以使吊板滿足舒適度要求. 吊板的峰值加速度隨吊板厚度及邊梁剛度的增加呈先上升后下降的趨勢. 因此在設(shè)計過程中,不應(yīng)一味地增加構(gòu)件的剛度,應(yīng)根據(jù)實際情況進行具體分析后再進行設(shè)計.
關(guān)鍵詞: 舒適度; 評價標準; 吊板; 剛度

Abstract:Firstly, the evaluation standards of floor comfort at home and abroad were introduced. Then, according to the" Technical Standard for Vibration Comfort of Building Floor Structures " ( JGJ/ T 441—2019 ) , the comfort design ofhanging board of hanging lecture hall in the library of Beihang Qingdao campus was conducted, and the MIDAS Gensoftware was used to carry out the numerical simulation analysis of the hanging lecture hall′s comfort, including the value ofmodeling parameters and the determination of the basic frequency of the hanging board, local model correctnessverification, load conditions and calculation results analysis. Finally, the key control parameters of the comfort design ofthe hanging board were analyzed. The results show that the local model can be a model including hanging column, hangingplate, hanging beam and adjacent span structure. The local model should be used as a benchmark to determine thefundamental frequency of the hanging plate by means of frequency sweeping. In the comfort design, the rigidity of thehanging beam should be ensured first, and then the thickness of the hanging plate and the rigidity of the side beam shouldbe adjusted to make the hanging plate meet the comfort requirements. The peak acceleration of the hanging plate rises firstand then decreases with the increase of the thickness of the hanging plate and the stiffness of the side beam. Therefore, inthe design process, the rigidity of the components should not be increased blindly, and the design should be carried outafter specific analysis according to the actual situation.
