    Realization Of Structural Dynamics


    3.1? 整體流線體型設計

    Overall Streamline And Shape Design


    為了塑造君康軒建筑特有的生生不息運動氣質,結構設計考慮將大懸挑、雙曲面、大跨度和桁架等元素有機結合,輕巧明快而不失層次感,打造出極具視覺沖擊力的建筑結構型體。

    In order to showcase the energizing, vigorous temperament of Royal Harmony Hub, elements such as large cantilever,double curved surface, large span and truss are applied as appropriate, which looks refreshing and structural, and creates a powerful, grand building.


    復雜結構與連續曲面的運用,勢必增大結構的分析難度,為此設計團隊采用多個軟件進行多維度的整體分析以及局部節點分析。立面上的切割線同時也是結構的重要元素,切口的位置是與結構充分討論后確定的,既有效提高結構的剛度,又兼顧了結構的延性。位移比是控制結構扭轉效應的關鍵指標,下表2列出在風荷載和地震荷載作用下結構整體在X和Y方向的位移情況,結果顯示:結構在兩個方向上的層間位移比和位移角均滿足規范要求,說明結構設計合理。

    The complex structure and continuously curved surface add difficulties in analyzing the structure. Therefore, the design team used varieties of software to analyze the overall structure and local joints from multiple dimensions. The cut line on the facade is also an important element of the structure, and the position of the cut is determined after deliberate discussion on the structure, which not only effectively improves the stiffness of the structure, but also takes into account the ductility of the structure.Displacement ratio is the key index to control the torsional effect of the structure. Table 2 below lists the displacement of the whole structure in X and Y directions under wind load and earthquake load action. The results show that the inter-storey displacement ratio and displacement angle of the structure in both directions meet the standard requirements, justifying that the structure design is well-considered and reasonable.

    3.2? 大懸挑桁架設計

    Design Of Large Cantilever Truss


    項目建筑體型為下部收進,上部外擴,結合建筑體型方案及內部空間,結構設計采用鋼結構懸挑桁架+下吊柱組合形式。桁架高度5米,最大懸挑達15米。懸挑桁架平面布置圖如圖所示。由于懸挑桁架跨度大且要實現整體流水曲線,以契合主體結構,因此為了確保大懸挑桁架受力性能達到最優,方案經過多次比選后決定采用斜拉桿布置形式。

    The building shape of the project features lower part retraction and upper part expansion. Combined with the building shape scheme and internal space, the steel structure cantilever truss and lower hanging column are adopted in the structural design. The truss has a height of 5 meters and a maximum cantilever of 15 meters. The layout of the cantilever truss is shown in the figure. Because the cantilever truss has a large span and needs to realize the overall curve to fit the main structure, in order to ensure the optimal mechanical performance of the large cantilever truss. And after comparing several schemes, we decided to adopt the arrangement of diagonal tie rods.

    采用斜拉腹桿,桁架深入于主體結構里面,以下吊柱形式,提高建筑空間使用率。對比發現,該方案在斜腹桿方面具有大的截面優化優勢,且主體結構配筋整體明顯下降。標準荷載作用下位移約40mm。下懸桿均有混凝土樓板,設計時沒有考慮混凝土的抗壓能力,僅作為二道防線考慮。

    Cable-stayed web members are adopted, and the truss is arranged into the main structure. The form of lower hanging columns is adopted to improve the utilization ratio of building space. By comparison, it is found that the scheme allows for large cross-section optimization in inclined web members, and the reinforcement of the main structure is obviously reduced as a whole. The displacement under standard load is about 40mm. The lower suspension rods all have concrete floors, and the compressive capacity of concrete is not considered in the design, but only considered as the second defensive line.

    3.3? 舒適度分析

    Comfort Analysis


    在地震作用下,樓板需要把水平力傳遞和分配到豎向抗側力構件,并協調本層各個豎向抗側力構件的變形。為了準確反應結構舒適度性能,通過有限元分析軟件SAP2000和YJK建立模型對比分析,大懸挑桁架舒適度指標[2]結果表明:在荷載作用下,SAP2000(整體模型)最大加速度為18.96mm/s2,出現在2位置,;SAP2000(一層模型)最大加速度為28.91mm/s2,出現在4位置;YJK(一層模型)最大加速度為48.40mm/s2,出現在8位置。懸挑樓蓋振動加速度和峰值加速度均滿足規范要求(峰值加速度限值56mm/s2)。計算結果說明,大懸挑桁架體系具有較好的整體穩定性,正常使用下具備較大的安全富余度。

    Under earthquake action, the floor needs to transfer and distribute the horizontal force to the vertical lateral force resisting members, and coordinate the deformation of each vertical lateral force resisting member on this floor. In order to accurately reflect the comfort performance of the structure, the finite element analysis software SAP2000 and YJK are used to establish a model for comparative analysis. The comfort index results of the large cantilever truss show that under the action of load, the maximum acceleration of SAP2000 (integral model) is 18.96mm/s2, appearing at position 2; the maximum acceleration of SAP2000 (1st layer model) is 28.91mm/s2, which appears at position 4; the maximum acceleration of YJK (1st layer model) is 48.40mm/s2, appearing at position 8. The vibration acceleration and peak acceleration of the cantilever floor meet the standard requirements (the peak acceleration limit is 56mm/s2). The calculation results show that the large cantilever truss system has good overall stability and large safety margin under normal use.

    3.4? 半圓鋼結構樓梯

    Semi-circular Steel Structure Stairs


    當形式在建筑中發揮作用時,美麗的事物就此產生。樓梯經常被看做為任何空間的焦點,許多設計師將樓梯的設計視為建筑內部的靈魂??缭降匕?,連通室和平分中庭,這些過渡結構在建筑中有著舉重若輕的地位。

    When form plays a role in architecture, beautiful things come into being. Stairs are often regarded as the focus of any space, and many designers regard the design of stairs as the soul inside the building. These transitional structures, such as crossing floor, connecting rooms and dividing atrium, have an important position in the building.


    中庭半圓鋼結構樓梯直徑達10米,由兩邊鋼板扶手+踏步板+封底底板構成。通過對鋼板扶手增加一個T型設計,從構造上增加扶手的穩定。

    The semi-circular steel structure staircase at the atrium has a diameter of 10 meters and consists of steel plate handrails on both sides, stepping plates and bottom cover plates. By adding a T-shaped design to the steel armrest, the stability of the armrest is increased in the structure.

    在進行線性屈曲分析時,經過計算,支座為鉸接時,樓梯屈曲因子為5.09;支座固接時,樓梯屈曲因子為5.85。均有著較大的屈曲因子,結構穩定性較好,滿足穩態要求。

    In the linear buckling analysis, through calculation, when the bearings are hinged, the buckling factor of stairs is 5.09; when the bearings are fixed, the buckling factor of stairs is 5.85. Both of them have large buckling factors, and the structural stability is good and compliant with requirements on steadiness.


    計算樓梯應力時,支座為鉸接時樓梯最大應力為222.9MPa,支座為固接時樓梯最大應力為262.8MPa。最大應力均出現在支座附近。從樓梯應力云圖可以看出,結構整體受力較好,滿足規范要求。

    When calculating the stress of stairs, the maximum stress of stairs is 222.9 MPa when the bearings are hinged and 262.8 MPa when the they are fixed. The maximum stress occurs near the bearing. It can be seen from the stress nephogram of stairs that the overall stress of the structure is good and meets the standard requirements.

    3.5? 大跨度鋼梁

    Long-span Steel Beam


    本項目游泳池上空鋼梁跨度達33米,鋼梁平面布置如圖所示。鋼梁截面選用HA14055-2536,為了保證樓板的連續性,鋼梁與框架柱連接時采用剛接設計,鋼次梁與混凝土框架梁連接時采用鉸接設計。大跨度鋼梁現場吊裝采用分段吊裝組合施工,以確保實現大跨度安全施工。

    The span of the steel beam above the swimming pool is 33 meters, and the plane layout of the steel beam is shown in the figure. HA14055-2536 is selected as the section of steel beam. In order to ensure the continuity of floor slab, rigid connection design is adopted when connecting steel beam with frame column, and hinged design is adopted when connecting steel secondary beam with concrete frame beam. Segmented hoisting combination construction is adopted for the site hoisting of long-span steel beams, to ensure the long-span safe construction.


    對大跨度鋼梁在地震組合工況下的變形進行了對比分析,分析結果表明構件的變形和承載能力均可滿足規范要求并能達到設計既定的性能目標。

    The deformation of long-span steel beams under the combined conditions of earthquake has been compared and analyzed, and the result shows that the deformation and bearing capacity of the structural components can meet the standard requirements and achieve the performance goals set by the design team.

    3.6? 曲面鋼結構網狀裝飾架

    Curved Steel Structure Mesh Decorative Frame


    主體結構四周環繞著曲率各異的曲面鋼結構網狀裝飾架,鋼構件的定位與節點連接是整個曲面網架的關鍵所在,本項目結合BIM模型設計,實現了現場構件精準定位。

    The main structure is surrounded by curved steel structure mesh decorative frames with different curvatures. The positioning of steel members and joint connection are the key points of the whole curved grid. The project applies BIM model design to ensure accurate positioning of field members.


    采用通用有限元分析軟件對曲面鋼結構連接節點進行受力分析,計算結果表明:最大應力出現在桿件交匯處區域,節點整體處于彈性范圍,可以滿足承載能力的設計要求。

    The general finite element analysis software is used to analyze the stress of the curved steel structure connection joints. The calculation results show that the maximum stress appears in the intersection area of the members, and the whole joint is in the elastic range, which can meet the design requirements of bearing capacity.

    Conclusion


    設計師安東尼·高迪曾說,“直線屬于人類,曲線屬于上帝”。然而,不愿“墨守成規”的結構團隊通過大膽的雙曲面和懸挑大跨結構元素,賦予了君康軒最極致的動感韻律。當我們重新審視這座建筑時,“桀驁不馴”的連續曲線正是其靈魂核心。

    Designer Antoni Gaud once said, "Straight lines belong to human beings while curves belong to God". However, the structural team’s boldness of not "sticking to the rules" has given Royal Harmony Hub the perfect dynamics by applying double curvature and cantilever and long-span structural elements. Curves are not exclusive to God. When we re-examine this building, we can see that the continuous curve is the core of its soul.
