The American Concrete Institute (ACI) 318-11 permits the use of the moment magnifier method for computing the design ultimate strength of slender reinforced concrete columns that are part of braced frames. This computed strength is influenced by the column effective length factor K, the equivalent uniform bending moment diagram factor Cm and the effective flexural…
Steel Structure Structures in which the members are made of steel and are joined by welding, riveting, or bolting. Because of the high strength of steel, these structures are reliable and require less material than other types of structures. Steel structures are distinguished by the diversity of their shapes and by their architectural expressiveness….
What is Pre-Engineered Building ? The scientific-sounding term pre-engineered buildings came into being in the 1960s. The buildings were pre-engineered because, like their ancestors, they relied upon standard engineering designs for a limited number of off-the-shelf configurations. Several factors made this period significant for the history of metal buildings.
