Engineering pre-engineered buildings

Article Abstract:

Engineering pre-engineered buildings may pose problems for structural engineers. Usually, structural engineers establish the design criteria for metal buildings after which the manufacturer provides the building design based on the given criteria. However, engineers have to design foundations without the final building reaction data. Evaluating existing metal buildings for new loadings can also present difficulties especially without fabrication drawings and calculations. An engineer can minimize his problems by forging ties with building manufacturers and exploring available methods and new reference materials.

Engineering a monument, evoking a nightmare

Article Abstract:

The US Holocaust Memorial Museum will stand as a monument to the Holocaust victims, house its historical documents and showcase its memorabilia. The design incorporates components reminiscent of concentration camps and the prisoners' tragic situation. The structural design team developed structural systems that will enhance the architectural design and accommodate permanent large-scale exhibit pieces which were installed during the early phase of construction. The design team also undertook careful detailing and fabrication of the exposed steel members to ensure the structure's stability.

Scaling the monument

Article Abstract:

The Washington Monument will undergo a $9 million restoration program that will integrate a unique scaffolding system. The scaffolding, which will be made from aluminum, will extend the monument's height while supporting worker access to the whole surface area. It also features a vertical transportation system for carrying personnel and materials. In addition, the scaffolding system supports a suitable foundation with spread footings.
