Bridging substance with style

Article Abstract:

The Damen Avenue Arch in Chicago, IL, is proof of the rich engineering and architectural heritage of the area. The 21.9 meter wide structure, which spans 94 cm was designed by Chicago-based J. Muller International. It features a two-way lane and sidewalks on each side. It employed three steel arch construction innovations. The fabrication of the arch from a large-diameter structural steel pipe and the absence of lateral bracing make it innovative in comparison with other steel arches. Its base is also filled with concrete for durability.

Swimming in style

Article Abstract:

The major challenge in building Deerfield Academy's $10 million athletic facilities structure, the natatorium, is its location in a floodplain. In order to construct the structure, the engineers had to provide an alternative runoff catchment area. The superstructure's materials included galvanized steel, structural steel, glue-laminated timber, and precast concrete. The facilities include an Olympic-sized lap swimming pool,a diving pool, three squash courts, and support infrastructure.

Investigating miracles, Italian-style

Article Abstract:

Luigi Garlaschelli and Franco Ramaccini investigate 'miracles,' such as the strange appearance of blood on certain objects. They have found that some art objects can emit mock secretions when holes are drilled in certain areas, and that the appearance of blood on food is actually a fungus.
