架构师提供的文本描述。当进入位于华盛顿州塔科马的新的LeMay博物馆的展厅时，游客们可能会发现自己凝视着天花板，同时也看到了一排排闪闪发光的经典汽车。一个由弯曲的胶合板梁组成的高耸屋顶系统，在给广阔的空间提供温暖、接地的审美的同时，也提供了一种惊人的壮丽感。绰号为“美国汽车博物馆”的这个占地16.5万平方英尺的设施是为了庆祝美国对汽车的热爱而建立的。在4层，9英亩的校园内，博物馆将容纳来自私人业主、公司的350辆轿车、卡车和摩托车，以及从1906年的凯迪拉克M型卡迪拉克到1965年的莲花赛车到1983年的DeLorean DMC 12的大量哈罗德·勒梅收藏。旋转的展品，如收集的玻璃罩装饰品，也将展出。

Text description provided by the architects. When entering the exhibit hall at the new LeMay Museum in Tacoma, Wash., visitors may find themselves gazing up at the ceiling as well as taking in the lines of gleaming classic cars. A soaring roof system made with curved glulam beams offers a striking sense of grandeur while simultaneously lending a warm, grounded aesthetic to the vast space. Nicknamed “America’s Car Museum,” the 165,000-square-foot facility was created to celebrate America’s love affair with the automobile. Across its 4-story, 9-acre campus, the museum will house up to 350 cars, trucks, and motorcycles from private owners, corporations, and the expansive Harold LeMay collection, from a 1906 Cadillac Model M to a 1965 Lotus racecar to a 1983 DeLorean DMC 12. Rotating exhibits, such as a collection of glass hood ornaments, also will be showcased.

除了展示一些世界上最令人敬畏的汽车外，博物馆还将成为汽车爱好者的聚集地，有会议空间、会员俱乐部、展览场地和计划好的教育中心。博物馆的主大厅基本上是一个长长的展厅，几乎像仓库一样，但由于其木材结构和周到的展示细节，它的美观得到了增强。由西方木材结构设计，弯曲屋顶系统是由19个格鲁兰框架与5-1/8英寸的胶合板，中间间隔4英尺作为二次框架。玻璃横梁，由美国层压板制作，测量8英寸-英寸的52.5英寸和弧线104英尺以上的显示器。由于屋面向两个方向弯曲，757个屋面的下垂都是独特的，有不同的复合人字形切口和不同的长度；每个吊架都有不同的斜度和斜度。1和1-8英寸全砂胶合板护套从Swanson集团Mfg。LLC覆盖屋顶，用半英寸和5/8英寸的薄板绕着角，以满足1-1/8英寸厚的要求，同时弯曲在17英尺的曲率半径附近。

Along with displaying some of the world’s most awe-inspiring vehicles, the museum will also serve as a gathering place for car enthusiasts, with meeting spaces, a membership club, a show field and a planned educational center. The museum’s main hall is essentially a long exhibit floor, almost warehouse-like, but aesthetically enhanced with its wood structure and thoughtful display details. Engineered by Western Wood Structures, the curved roof system was created with 19 glulam frames with 5-1/8-inch glulam purlins spaced 4 feet on center as secondary framing. The glulam beams, crafted by American Laminators, measure 8-¾ inches by 52-½ inches and arc 104 feet over the displays below. Because the roof curves in two directions, each of the 757 roof purlins is unique, with varying compound miter cuts and varying lengths; each purlin hanger has a different skew and slope. One-and-one-eighth-inch fully sanded plywood sheathing from Swanson Group Mfg. LLC covers the roof, with ½-inch and 5/8-inch sheets used around corners to meet the 1-1/8-inch thickness requirement while bending around the 17-foot radius of curvature.

防水、刚性保温和金属屋面完整的结构。拱形设计-世界上最大的木弯矩框架之一-具有1小时的耐火等级，并遵循2009年国家减少地震危险计划规定的“结构粘合层合木拱门构件及其连接结构抗震设计的特殊要求”。这些规定旨在通过允许钢连接在地震中以塑性方式屈服，并防止胶合板构件以脆性方式失效，从而产生拱系统的延展性。在结构的南端，屋顶系统悬挑在最后的玻璃拱上，支撑着弯曲的筋膜，并创造了一个有盖的室外聚集空间。洛杉矶格兰特普莱斯建筑师事务所的联席董事艾伦·格兰特(AlanGrant)说，使用Glulam光束的决定并不纯粹是美学的，因为它也是一些必要的节省成本以满足紧缩预算的功能之一。

Waterproof rigid insulation and a metal roof complete the structure.   The arch design—one of the largest wood moment frames in the world—has a 1-hour fire-resistive rating and follows the “Special Requirements for Seismic Design of Structural Glued Laminated Timber Arch Members and Their Connections in Three-Hinged Arch Systems” from the 2009 National Earthquake Hazards Reduction Program provisions. The provisions are intended to produce ductility in the arch systems by allowing the steel connections to yield plastically during a seismic event and prevent glulam members from failing in a brittle fashion.   At the south end of the structure, the roof system cantilevers over the last glulam arch, supporting the curved fascia and creating a covered outdoor gathering space.   The decision to use glulam beams wasn’t purely aesthetic, as it also was one of several features that allowed some of the cost savings necessary to meet a tight budget, says Alan Grant, co-director of Grant Price Architects in Los Angeles.

格兰特说，LeMay博物馆的建造成本约为104英镑，而典型的博物馆的价格从400美元到800英镑不等。从外部看，弯曲的金属顶屋顶的效果是闪闪发光和流线型的-很像汽车的空气动力学表面。建筑师们非常小心地确保现代的形式和大小仍然尊重塔科马在很大程度上具有历史意义的建筑，从周围的建筑中脱颖而出，包括邻近的塔科马穹顶，而不超过它们。在内部，格兰特仍然意识到结构的主要功能-展示闪亮的汽车-在考虑材料时。例如，地板是深色的混凝土，就像道路汽车制造商在设计汽车外壳以达到最佳视觉效果时所考虑的那样。

Grant says that construction of the LeMay museum cost about $104 psf whereas typical museums can range from $400 to $800 psf. From the outside, the effect of the curved, metal-topped roof is gleaming and streamlined—much like the aerodynamic surfaces of an automobile. The architects took great care to ensure the modern form and size still respected Tacoma’s largely historic architecture, standing out from the surrounding buildings, including the adjacent Tacoma Dome, without overpowering them. Inside, Grant remained conscious of the structure’s primary function—showcasing shiny automobiles—when considering materials. Flooring, for example, is dark stained concrete, much like the roadways automakers consider when designing a car’s shell for optimal visual effect.

格兰特还密切关注灯光的选择，指出车展上的光点或条形装置往往会在照片中留下亮点和眩光。事实证明，这个解决方案既简单又便宜：吊具可以分散40%的光线，60%的光线下垂，前面有一根炽热的导火索，形成一种强大而明亮的灯光，让空间发亮。6月2日LeMay博物馆的盛大开幕，标志着它的创始人、捐助者和建筑团队近十年的努力划上了句号。由此产生的空间不仅在美学和结构上受到赞赏，而且成功地为汽车爱好者提供了见证历史、分享激情和保存美国遗产的场所。(鼓掌)

Grant also paid close attention to lighting selection, noting how spot or strip fixtures at auto shows often leave bright spots and glare in photographs. The solution turned out to be simple and inexpensive: hanging fixtures that disperse 40 percent of the light up and 60 percent down, with a glowing fuse across the front, creating a strong, bright light that sets the space aglow.    The grand opening of the LeMay Museum June 2 capped off nearly a decade of effort by its founders, benefactors and construction teams. The resulting space is not only one to be aesthetically and structurally admired, but one that succeeds in providing a place for car lovers to witness history, share passions and preserve an American legacy.
