Reshoring prevents the concrete from moving, or in this case deflecting, Under a suspended concrete structure for a period of time after theįormwork has been removed, usually requires its own engineering design. Such as higher strength concrete, high-tensile reinforcing steel,Īnd more advanced curing techniques to apply after the concrete hasīeen placed in the formwork.
More has been learned, and today there are many tools to employ, Given the limited use of such designs at that time, it is understandable that engineers may not have fully understood the forces imposed in a cantilever.Īs the use of concrete has become more widespread over the years, Such cantilevers were a relatively new design element in the 1930s, and reinforced concrete technology itself had not progressed much beyond simple, direct bearing configurations. Perhaps the most striking single feature of Fallingwater is the cantilevered reinforced concrete balconies that extend out over the falls. Join usĪs we experience the ultimate challenge in constructing the country Yet another challenge-one with potentially fatal consequences:Ī progressing failure in the building’s structure. The supporting concrete bolsters, and further complicated by theĭifficulty in finding a competent contractor.įinally, when work began in earnest the project was plagued with Without significant progress, beginning with Edgar Kaufmann’sĭoubts about the structure, followed by late changes by Wright in Atkins, courtesy of the Western Pennsylvania Conservancy.Īs described last month in Part 4, construction finally began onįallingwater after a much delayed start.
