简介

Introduction

锐驰（Camerich）嘉兴园区在其厂区的西北角建设了一座高约33.0m的消防水塔，设计完成于2022年，并于2024年秋天落成。水塔作为园区内最高的建筑物，除消防使用目的之外，更是成为了园区的标志性景观建筑和供人登高俯瞰的观光平台。

Camerich Jiaxing Campus has recently built a water tower for fire water supply purpose with a height of about 33.0m in the northwest corner of its factory area. The design was finished in 2022 and the construction was completed in the fall of 2024. As the tallest building in the campus, the water tower has become a landmark landscaping structure in the campus and a sightseeing platform for people to climb and enjoy the beautiful view from the top.

水塔的几何形体由建筑工作室SEMESTER STUDIO确定，同时通过结构方案优化，兼顾实现了轻巧、有趣的造型和高效、经济的受力体系

。

The geometry of the water tower was determined by the architecture studio SEMESTER STUDIO, and the structural scheme was optimized to achieve a lightweight and interesting structural shape and an efficient and economical force system.

云朵水箱及幕墙设计

Cloud-shaped water tank with curtain wall

水箱的造型打破了传统的圆筒型或箱型的水箱造型，设计师受启发于诗句

"a cloud is a lake in the sky."

，创新性地采用了云朵般的水箱造型，并赋予了它富有诗意的名字—— “云想水塔”（

Rain Rain Go Away

）。云朵的造型不仅富有诗意，从结构效率的角度，构成云朵的不同曲率大小的外凸型圆弧更是提高了结构在水荷载和风荷载下的整体稳定性

。

The shape of the water tank breaks the traditional cylindrical or box-shaped water tank shape. Inspired by the poem "a cloud is a lake in the sky", the designer innovatively adopted a cloud-like water tank shape and gave it a poetic name - "Rain Rain Go Away". The cloud shape is not only poetic, but from the perspective of structural efficiency, the convex arcs of different curvatures that make up the cloud shape also improve the overall stability of the structure under water loads and wind loads.

水箱由型钢底架、4mm底板、箱梁框架、立面及顶面压型钢板组成。

The water tank consists of a steel frame, a 4mm bottom plate, a box beam frame, and corrugated steel plates on the facade and top.

水塔顶部的云朵形幕墙结构将水箱和托梁包裹在内部。幕墙的自重荷载和作用在幕墙上的水平荷载通过牛腿螺栓连接节点传递至水箱顶面外圈及内圈边梁。

The cloud-shaped curtain wall structure on the top of the water tower wraps the water tank and the joists inside. The dead load of the curtain wall and the horizontal load acting on the curtain wall are transferred to the outer and inner edge beams of the top surface of the water tank through the corbels with bolted connection.

水塔主体结构

Main structure of the water tower

水塔主体支撑结构由悬臂托梁、斜柱、横杆组成。设计师巧妙地将水箱的进出水管隐藏在与其外观相同的12根斜柱之间，斜柱的布置呈上窄下宽的A字型。12根塔架斜柱和30根连接横杆的排布经过精细的考量和计算，同时实现了视觉效果的灵动趣味性和结构的有序高效性。

The main support structure of the water tower is composed of cantilever beams, inclined columns, and crossbars. The designer cleverly hides the water inlet and outlet pipes of the water tank between 12 inclined columns with the same appearance. The inclined columns are arranged in an A-shape with narrow top and wide bottom. The arrangement of the 12 inclined columns and 30 connecting crossbars has been carefully considered and calculated, achieving both the agile and interesting visual effect and the orderly and efficient structure.

塔架斜柱共6对12根。根据其几何位置的确定原则可分为两类。其中第一类斜柱包

含4对共8根，取自一个底直径7.0m、顶直径3.5m、高30.0m的双曲抛物面，空间位置完全对称。这类斜柱在高约20m处相交，形成4个X型交点，交角为13.51°。

The 12 inclined columns are from 6 pairs. They can be divided into two categories according to the principle of determining their geometric positions. The first type of inclined columns includes 4 pairs with a total of 8 columns, which are taken from a hyperbolic parabola with a bottom diameter of 7.0m, a top diameter of 3.5m, and a height of 30.0m. The spatial position is completely symmetrical. This type of inclined columns intersects at a height of about 20m, forming 4 X-shaped intersections with an intersection angle of 13.51°.

为了增加结构视觉效果的趣味性，第二类的2对斜柱不对称地布置在整体结构中。但它们空间位置的选择也是经过精心选定的。布置的选择在增强结构的整体性的同时也兼顾了后期X型节点制作施工的便利性。

In order to increase the interest of the visual effect of the structure, the second type of two pairs of inclined columns are arranged asymmetrically in the overall structure. However, the choice of their spatial positions is also carefully selected. The choice of arrangement not only enhances the integrity of the structure, but also takes into account the convenience of the X-shaped node production and construction.

连接横杆共30根，与斜柱刚接，分别在8.0m、14.0m、20.0m高度处形成三个闭合的圆环，增强了结构的整体性。横杆的布置在确保给斜柱提供有效侧向约束的同时，尽可能地高低错落排布，视觉上错落有致。

There are 30 connecting crossbars in total, which are rigidly connected to the inclined columns, forming three closed circles at heights of 8.0m, 14.0m, and 20.0m, respectively, which enhances the integrity of the structure. The arrangement of the crossbars ensures that effective lateral constraints are provided to the 12 inclined columns, while being arranged as high and low as possible, which is vividly staggered.

抗侧力体系与风荷载验算

Lateral force resisting system and wind load check

作为顶部迎风面较大的高耸结构，水塔的抗侧力体系设计和风荷载下结构承载力极限状态验算、稳定性应力验算和水平位移校核是本项目设计的重点。

As a tall structure with a large windward surface at the top, the design of the water tower's lateral force resistance system and the ultimate limit state calculation of the structural bearing capacity under wind load, stability stress calculation and horizontal displacement verification are the key points of the design of this project.

水塔每对斜柱间的夹角约为13°，柱顶与刚性平台刚接，柱脚采用外包式柱脚。6对斜柱通过直接相交或连接横杆形成了更有效的空间协同受力体系。

The angle between each pair of inclined columns of the water tower is about 13°, the top of the column is rigidly connected to the rigid platform, and the column foot adopts an embedded column footing. The 6 pairs of inclined columns form a very effective spatial force resisting system by directly intersecting or connecting crossbars.

水塔在水平荷载作用下的变形示意

风荷载取值依据《建筑结构荷载规范》及二维平面CFD数值模拟。由于云朵幕墙结构的平面形状不规则、不对称，风荷载的合力方向与来流方向存在夹角，并且会受到风的扭转作用。例如下图为0度风向角下CFD模拟结果。

The wind load value is based on the "Building Structure Load Code" and two-dimensional plane CFD numerical simulation. Due to the irregular and asymmetric plane shape of the cloud curtain wall structure, the resultant force direction of the wind load is at an angle to the incoming flow direction, and it will be torsionally affected by the wind. For example, the figure below shows the CFD simulation results under a wind direction angle of 0 degrees.

0度风向角下CFD模拟结果

在进行云朵幕墙横截面的二维平面CFD模拟时，该形体表现出了较为明显的横风向漩涡脱落效应。因此我们进一步依据《高耸结构设计标准》GB50135-2019衡量了本结构的横风向风振效应。计算结果显示，结构处于跨临界范围，漩涡脱落呈现以确定性周期振动为主的特性，经计算，本项目水塔顶部风速V_H的1.2倍未达到临界风速V_cr，结构整体均处于非共振区，不发生横风共振。

When conducting a two-dimensional plane CFD simulation of the cross-section of the cloud curtain wall, the shape exhibited a relatively obvious crosswind vortex shedding effect. Therefore, we further measured the crosswind effect of the structure according to the Design Standard for Tall Structures GB50135-2019. The calculation results show that the structure is in the transcritical range, and the vortex shedding presents the characteristics of deterministic periodic vibration, and the calculation shows that 1.2 times of the wind speed VH

at the top of the water tower of this project does not reach the critical wind speed Vcr, and the structure as a whole is in the non-resonance zone, and crosswind resonance does not occur.

在动力风荷载下，除了静水力外，还应考虑水箱内部水体对水箱侧壁和底部施加的脉冲和对流流体动力。为了分析其中流体动力带来的影响，本项目选取多条风速时程曲线，通过等效的弹簧质量模型进行分析。结果表明，在不同的时程风荷载作用下，结构最大位移均小于静力风荷载下的结果。因此说明静力风荷载中按规范取得的风振系数取值2.72是足以包络住高位水箱水体对流效应对结构的影响的。

Under dynamic wind loads, in addition to hydrostatic forces, the impulsive and convective hydrodynamic forces exerted by the water body inside the tank on the sidewalls and bottom of the tank should also be considered. In order to analyze the effects of fluid dynamics, this project selected a number of wind speed time history lines and used equivalent spring mass models for analysis. The results show that the maximum displacement of the structure under different time history wind load is all smaller than that under static wind load. Therefore, it shows that the value of the wind vibration coefficient of 2.72 in the static wind load as per GB code is enough to capture the influence of the convection effect of the water body of the high-elevation tank on the structure.

Afterword

2024年9月初，在水塔主体结构建设完成之际，sbp有幸受邀来到锐驰嘉兴园区，一睹这座凝结了主业和设计师们巧思和匠心的景观水塔。水箱定期清空进行维护。当日我们十分幸运地目睹了水阀打开后，水从30米高空沿着云朵水箱外围一圈排水系统洒落下来的美丽画面，随后彩虹出现，心情激动不已。

"A cloud is a lake in the sky

”

，此刻，云想水塔就像是一朵雨做的云。

In early September 2024, when the construction of the main structure of the water tower was completed, sbp was fortunate to be invited to Camerich Jiaxing Campus to see this landscaping water tower that embodies the ingenuity and craftmanship of the client and designers. The water tank is emptied regularly for maintenance. On that day, we were very lucky to witness the beautiful scene of water spilling down from a height of 30 meters along the drainage system around the perimeter of the cloud-shaped water tank after the water valve was opened, then a rainbow appeared, and we were very excited. “A cloud is a lake in the sky”, at that moment, the water tower appears as a rain cloud in the sky.
