Certain viaducts of the Chicago "L" system. A regular, periodic configuration of points, particles, or objects throughout an area or a space, especially the arrangement of ions or molecules in a crystalline solid.The sides of the Cape Fear Memorial Bridge.The internal structure of the Statue of Liberty.The western span has been retrofitted with bolted plates replacing the lacing for added strength. 1300, from Old French latiz 'lattice,' from late 'lath, board, plank, batten' (Modern French latte ), from Frankish or some other Germanic source, such as Old High German latta 'lath' (see lath ). The obsolescent eastern span of the San Francisco–Oakland Bay Bridge. Choosing a lattice structure for an organization comes with the following benefits: Cost savings: Adopting a lattice structure in an organization saves money since businesses dont have to hire multiple managers to oversee teams. lattice (n.) 'work with open spaces formed by crossing or interlacing of laths, bars, etc.,' c.In some case seismic retrofit modifications replace riveted lacing with plates bolted in place.Įxamples of laced struts or ties If we want to make it clear what partial ordering the lattice is based on, we say it is a. Since a lattice L is an algebraic system with binary operations and, it is denoted by L. As with lattice girders, laced struts and ties have generally been supplanted by hollow box sections, which are more economic to produce with modern technology. A lattice is a poset (L, ) for which every pair of elements has a greatest lower bound and least upper bound. The lacing elements are typically attached using either hot rivets or threaded locator bolts. The component sections may typically include metal beams, channel and angle sections, with the lacing elements either metal plate strips, or angle sections. Lattices: Let L be a non-empty set closed under two binary operations called meet and join, denoted by and. A lattice girder, like any girder, primarily resists bending. This form allows a strut to resist axial compression and a ( tie) to resist axial tension. The term is also sometimes used to refer to a laced strut or laced tie, structural members commonly made using a combination of structural sections connected with diagonal lacing. It has been supplanted in modern construction with welded or bolted plate girders, which use more material but have lower fabrication and maintenance costs. The lattice girder was used prior to the development of larger rolled steel plates. As the material is work hardened it becomes increasingly saturated with new dislocations, and more dislocations are prevented from nucleating (a. The defect-free lattice can be created or restored at any time by annealing. Laced vertical struts and diagonal ties on the cantilever portion of the now-demolished eastern span of the San Francisco–Oakland Bay Bridge)Ī lattice girder is a truss girder where the load is carried by a web of latticed metal. Before work hardening, the lattice of the material exhibits a regular, nearly defect-free pattern (almost no dislocations). lattice work synonyms, lattice work pronunciation, lattice work translation, English dictionary definition of lattice work.
