Diagonal bracing remains a vital interior part of many roof systems, and in-wall wind braces are required by building codes in many municipalities or by individual state laws in the United States. Modern light-frame structures usually gain strength from rigid panels ( plywood and other plywood-like composites such as oriented strand board (OSB) used to form all or part of wall sections), but until recently carpenters employed various forms of diagonal bracing to stabilize walls.

Light-frame construction using standardized dimensional lumber has become the dominant construction method in North America and Australia due to the economy of the method use of minimal structural material allows builders to enclose a large area at minimal cost while achieving a wide variety of architectural styles. īuilding framing is divided into two broad categories, heavy-frame construction (heavy framing) if the vertical supports are few and heavy such as in timber framing, pole building framing, or steel framing or light-frame construction (light-framing) if the supports are more numerous and smaller, such as balloon, platform, or light-steel framing. The alternative to framed construction is generally called mass wall construction, where horizontal layers of stacked materials such as log building, masonry, rammed earth, adobe, etc. Framing materials are usually wood, engineered wood, or structural steel. The erection of a wooden frame in Sabah, Malaysiaįraming, in construction, is the fitting together of pieces to give a structure support and shape.

A winner of the 2013 Booth Family Rome Prize in Historic Preservation and Conservation at the American Academy in Rome, he is at work on a study of the buildings of the Italian engineer and architect Pier Luigi Nervi.A wooden-frame house under construction – in this example of platform framing the location of the upper floor is readily discerned by the wide joists between the floors, and the upper structure rests on this platform. He is the author of Chicago Skyscrapers, 1871-1934 (Champaign: University of Illinois Press, 2013), among other books. Thomas Leslie is the Morrill Pickard Chilton Professor in Architecture at Iowa State University, where he researches the integration of building sciences and arts both historically and in contemporary practice. His 2014 study, “Structure in Skyscrapers: History and Preservation” was the inspiration for the exhibition,“TEN & TALLER, 1874-1900.” Speakersĭonald Friedman, a structural engineer, is the president of Old Structures Engineering and author of several books, including Historical Building Construction (1995, rev. New Yorker Donald Friedman, a structural engineer and author of Historical Building Construction, and architect and historian Thomas Leslie, author of Chicago Skyscrapers, 1871-1934, reviewed the introduction and adoption of early steel skeletons in the 19th century’s two leading skyscraper cities. The second session featured two experts on the history of architecture and engineering who have researched and published extensively on the beginnings of metal-frame construction in New York and Chicago.
