One of the towers primarily contains gallery space while the other houses offices and a library. Weiskopf & Pickworth\u2014since 2002, a part of Severud Associates\u2014incorporated triangular elements into the structural design as well, embracing the famed architect\u2019s vision despite its stark contrast to the right angles and ornamentation of the neoclassical West Building.<\/br><\/br><\/p>\n

Most notably, the roof of the central courtyard consists of a steel space truss composed of interconnected tetrahedrons, the inclined faces of which support glass panels. In addition, the large, open gallery spaces are framed with three-way, triangular waffle slabs supported by triangular concrete columns. The building\u2019s foundation consists of a six foot thick concrete mat slab, which is anchored to the ground to maintain stability and resist hydrostatic uplift. A two-level underground passage connects the East and West Buildings and also houses public amenities.<\/p>\n

The National Museum of the American Indian occupies one of the last undeveloped sites at the southeast corner of the mall in Washington, D.C. Advised by members of Native American communities, the design team created a building that uses architectural features to reflect the culture of North America\u2019s indigenous peoples. The curvilinear stone-clad form of the museum\u2019s exterior, for example, was designed to look like windswept rock formations and to convey the importance of the natural world.

To engineer this complex five-story structure, Severud Associates combined different framing systems. Concrete slabs, columns, and walls support most of the building, including the stair and elevator cores that also resist lateral loads. Interconnected steel trusses, anchored to the core walls, enable the east end of the building to cantilever dramatically. The cantilever is capped by a steel dome with an oculus open to the heavens to reflect another important aspect of Native American culture.<\/p>\n

\"NationalThis monumental building, originally named the Museum of History and Technology, was one of the last major designs by the acclaimed architectural firm of McKim, Mead and White (the project was completed by its successor firm, Steinman, Cain and White). The architectural design melded the classical style of traditional government buildings with the Modernism popular at the time of its opening in 1964. For example, the building is clad with three-story-high marble panels that alternately project and recede, mimicking a colonnade and creating window openings while remaining minimalist in detail.<\/br><\/br><\/p>\n

Severud Associates\u2019 structural design of the interior called for columns on a 50-foot grid to provide maximum flexibility in the exhibition spaces. Due to the poor soil and high water table at the museum\u2019s site near the Potomac River, the columns bear on piles driven to bedrock and the foundation was designed for hydrostatic uplift. A central flag hall, open for the full height of the building, allowed the Star-Spangled Banner that flew over Fort McHenry and inspired the lyrics of the national anthem to hang vertically (the flag has since been moved).<\/br><\/br><\/p>\n

United States Holocaust Memorial Museum <\/b><\/p>\n

\"USIn 1993, the newly constructed limestone and brick-clad United States Holocaust Memorial Museum opened its doors and invited the public to experience a dark period of world history. Intended to provoke emotional discomfort, the architectural design incorporates visual features reminiscent of concentration camps. This is most evident in the Hall of Witness, a three-story-high atrium flanked by eight \u201cguard towers.\u201d Pairs of towers are linked by steel and glass pedestrian bridges whose exposed built-up members and bolted connections speak the vernacular of 1930s steel construction.<\/br><\/br><\/p>\n

As part of its structural design, Weiskopf & Pickworth\u2014since 2002, a part of Severud Associates\u2014worked closely with the steel contractor to painstakingly detail each member and connection to meet the architect\u2019s vision. The same attention to detail was applied throughout the building, including the atrium\u2019s glazed roof, with its skewed skylight, and the adjacent Hall of Remembrance, a hexagonal tower with outwardly sloping interior walls and pyramidal skylight. The floor of the hall spans 62 feet over a theater below while compression and tension rings resolve the lateral forces induced by the sloping walls.<\/p>\n","protected":false},"excerpt":{"rendered":"
