Welded Steel Structures - an overview ScienceDirect Topics

An existing welded steel structure was designed for a pipe reaction load F y = 250 lb (Figure 5.18(a)).The existing valve near the support was replaced by a new,heavier valve,which brought the total load on the support up to F = 424 lb.Engineering is asked whether the existing support can take the new increased load.In this example,there is no lateral pipe load on the support,only the US4989752A - Frangible roof joint for storage tanks The American Petroleum Institute (API) has developed a standard for the design and construction of welded steel storage tanks.This standard provides for the design of a frangible roof joint,but in 1978 the standard was amended to limit applicability of the frangible roof design to tanks having a diameter of fifty feet (15.2m) or more.Technical Inquiries for API Standard 620,Design liquid and for an earthquake induced compression stress,the allowable compression stress need not be limited for biaxial stress as otherwise may be required by Figure 3 1 be restated as For tanks full or partially full of liquid subjected to a local axial compressive buckling stress in a cylindrical shell from a moment in the cylinder
