公共藝術(shù)不應該只是裝飾，它應該改善用戶體驗并提高一個地方的活力。作為新的彭布羅克派恩斯市中心的一部分，包括一個公共廣場，一個3500個座位的表演藝術(shù)大廳，市政廳和弗蘭克藝術(shù)畫廊，建筑師設計了廣場雕塑和并加入景觀特色以補充這些活動和功能。

本次選擇地震分析處理軟件GSAC(來自于美國圣路易斯大學)完成地震記錄預處理，根據(jù)地震臺站所得三分量原始記錄去均值，同時消除直流成分與儀器相應，將P波前10s定義成起點，由時窗(寬度為100s)截取P波波形，該寬度下同樣存在最深界面多次反射波震相；隨后，需要完成兩水平分量旋轉(zhuǎn)分量，獲得徑向、切向分量；此時，以時間域為前提，通過垂直分量完成所得分量的最大熵譜反褶積，能夠得出徑向、切向接收函數(shù)。運算期間，接收函數(shù)需要進行低通濾波處理，本次選擇高斯濾波器來處理，系數(shù)是2.5。最后，明確接收函數(shù)(相關(guān)性佳、多次反射波較直觀)進行臺站下方地殼上地幔結(jié)構(gòu)分析與探討。

本質(zhì)上來說，彭布羅克派恩斯是個沒有城市的城市（沒有商業(yè)區(qū)或社區(qū)空間），而新的市中心和門戶雕塑提供了過去沒有的社區(qū)活動點。在預算有限的情況下，建筑師結(jié)合廣場雕塑設計和景觀元素，在塑造去往新的公共廣場行人通道的同時，提供和導向和強調(diào)一種到達的感覺。

設計作為公共藝術(shù)，這個不銹鋼雕塑像樹干般“生長“出來并往一排在南佛羅里達州微風中搖曳著的穿孔板。閃爍暗淡的光影塑造了雕塑下的體驗，就像是走進了一堆鳳梨，如同亞熱帶硬木森林的感覺一樣。

雕塑提供了一個陰涼的座位區(qū)域，以及可調(diào)節(jié)的照明以提高日夜的用戶體驗。在表演和藝術(shù)活動期間，這個廣場將是展前和展后活動的會議場地，也是社區(qū)聚會場所。

可持續(xù)性目標——雖然彭布羅克派恩斯廣場雕塑沒有機電系統(tǒng)或其他需要公用電網(wǎng)持續(xù)資源的組件，但該結(jié)構(gòu)的設計和構(gòu)造能夠持續(xù)很長時間，并保持即使在南佛羅里達州嚴酷的沿海條件下也可以免維護。

Public art should not be merely decoration or after thought,it should enhance user experience and celebrate a place.As part of the new Pembroke Pines City Center that includes a public plaza,a 3,500 seat performing arts hall,the city hall and The Frank art gallery for the City of Pembroke Pines,the architect designed the Gateway Sculpture and attending landscape features to complement these activities and programs.

Essentially Pembroke Pines was a city,without a city (no downtown or community space) and the new City Center and Gateway Sculpture provide a community anchor that did not exist prior.With a limited budget,the architect worked with The Gateway Sculpture and landscape elements frame a pedestrian gateway into a new public plaza,providing way-finding and anchoring a sense of arrival.

Designed as public art,the stainless steel sculpture emerges as tree columns that lead up to an array of perforated plates that appear to spin in the continuous breeze of south Florida.The experience under the sculpture creates a dappled light effect as you walk between bromeliad mounds—an experience like that of a subtropical hardwood forest.

The sculpture provides a shaded area for seating,as well as programmable up lighting that enhances user experience day or night.During performance and art events the Gateway will be a meeting ground for pre and post-show activities,and a gathering place for the community.

SUSTAINABILITY OBJECTIVES -While the Pembroke Pines Gateway Sculpture has no mechanical systems or other components that require continued resources from the utility grid the structure is designed and constructed to last well into the future and remain maintenance free from the harsh coastal conditions of south Florida.

三重底線的措施是在它能夠滿足客戶的能力與預算范圍內(nèi)的前提下構(gòu)想出來的。這是通過材料耐久性實現(xiàn)的，其中不銹鋼用于低碳鋼以確保結(jié)構(gòu)的壽命。還采用了對環(huán)境敏感的耐用油漆。

因為場地是在一個人流量很大并有很多集散空間的路線上，傳統(tǒng)的粉末涂料不能輕易滿足簡單的維護，因為劃痕或其他問題很可能經(jīng)常出現(xiàn)。所以采用對環(huán)境敏感的耐用油漆，可以使運市政清潔員能夠在正常保潔制度下輕松維護結(jié)構(gòu)，是該雕塑的經(jīng)濟可持續(xù)性的關(guān)鍵所在。

另一個主要目標是在佛羅里達南部的炎熱潮濕的氣候中提供陰涼處。公共廣場已經(jīng)有大量的硬質(zhì)地景，而這個廣場雕塑為了保持環(huán)境舒適，提供了必要的遮陰。

最后，環(huán)繞這個雕塑的大面積綠化帶，把整座建筑和廣場上不滲水的硬質(zhì)鋪地的雨水收集起來。這簡直就是熱帶雨林花園，綠化帶包括了具有鮮艷色彩并與本土品種兼容的植被，以增強用戶體驗，同時也為本地的野生動物提供重要的避護所和棲息地。

A triple-bottom-line approach was conceived of that worked within the client's abilities and budget.This is achieved through material durability where stainless steel was used over mild steel to ensure the longevity of the structure.A durable paint that is environmentally sensitive was also employed.

Understanding the location is within a heavily used pedestrian path and gathering space,traditional powder coating could not be used simply for the ease of maintenance where scratches or other issues may arise.This allows for city staff to easily maintain the structure under normal maintenance regimes and was key to the economic sustainability of the structure.

Another primary objective was to provide shade in the hot-humid climate of south Florida.The public plaza has a tremendous amount of hardscape and the Gateway Sculpture provides essential shade in order to maintain environmental comfort.

Lastly,large planting areas surround the structure collecting stormwater from the entire building and impervious hardscape of the plaza.Essentially rain gardens,these planters include native facultative landscape material with vibrant color to enhance user experience and provide critical refuge and habitat to native wildlife.
