無(wú)明確使用方的辦公樓設(shè)計(jì)通常被安全、日照等常規(guī)因素所左右。在分析了很多辦公樓案例之后,我們決定在這個(gè)位于鄭東新區(qū)的高層建筑中采用典型的直線形平面加核心筒結(jié)構(gòu),同時(shí)積極尋找改進(jìn)的機(jī)會(huì)。
The design of speculative office towers is usually dictated by sets of conventions such as safety concerns and natural light. The project, a high-rise speculative office tower, is located at the Zhengdong New District in the city of Zhengzhou. After studying various precedents, we decided to accept the prototypical, rectilinear plan with centralized cores as a starting point while looking actively for improvements during the design process.
基地形狀
Site geometry
場(chǎng)地的條件恰好提供了改進(jìn)上述原型的機(jī)會(huì):環(huán)繞人工湖的一組建筑形成了一個(gè)巨大的圓環(huán),作為圓環(huán)一部分的場(chǎng)地為帶有少許弧度的矩形。我們認(rèn)為盡管這個(gè)弧度很含蓄,也應(yīng)該將其體現(xiàn)出來(lái)。于是,我們把典型的矩形平面變成了“之”字形,從而為原本呈方形的建筑體量增加了一種垂直性。
An opportunity for improvement was presented by the site itself—a slightly curved rectilinear parcel that is a part of a monumental ring around an artificial lake. We believe the curvature, however subtle, should be acknowledged and so transformed the rectangular plan into a zigzagged configuration. Such move also added a sense of verticality to an otherwise blocky volume.
平面和空間
Floor plan and space
“之”字形的折線形成鋸齒形平面,提供了更多的陽(yáng)角空間和更好的視野,使開(kāi)放空間感覺(jué)起來(lái)更像一組小尺度空間的組合。
The zigzag configuration offers a floor plan with multiple corners for better views and a sense of spatial aggregation brought by the smaller increments.
在剖面上,我們?cè)趦蓚€(gè)核心筒之間設(shè)置了一個(gè)中庭,兩組廊橋穿越其中。這樣的設(shè)計(jì)讓人們?cè)诮ㄖ?nèi)部也可以感受到建筑的垂直性以及空間的戲劇性。
In sectional design, we devised between the cores an atrium that penetrates all floors and spanned by footbridges so the building’s dramatic verticality can be experienced from within.
結(jié)構(gòu)和經(jīng)濟(jì)
Structure and economy
我們采用了核心筒+外圍密柱的無(wú)梁鋼筋混凝土結(jié)構(gòu),使得內(nèi)部空間完全開(kāi)放、靈活,可以根據(jù)需要分隔成不同大小的辦公室。無(wú)梁結(jié)構(gòu)使我們得以在降低層高的同時(shí)保持空間凈高,在建筑總高度不變的情況下多做出一層使用空間。
The beam-free, reinforced-concrete structural system with central cores and peripheral columns creates a total open space flexible for further division. Without beams, we were able to reduce the floor height— but not the ceiling height— to include an extra floor within the building height limit.
立面設(shè)計(jì)
Facade design
外圍的密柱為承重與自然通風(fēng)的功能相間布置,密柱被設(shè)在圍護(hù)界面之外,進(jìn)一步加強(qiáng)了建筑的垂直感。我們將高樓層的柱子扭轉(zhuǎn)一定的角度,到低樓層則每?jī)筛蠟橐桓瑥亩WC低樓層的室內(nèi)外空間有充分互動(dòng)。
Peripheral columns for load bearing and natural ventilation are placed in alternation outside the building enclosure, reinforcing the vertical composition of the volumes. Neighboring columns twist and converge with the descending height for better indoor-outdoor interaction on the lower floors.
