The staggered truss structural system consists of story-high steel trusses placed on alternating column lines on each floor so that the long axis of one truss is always between the trusses on the floor below. [4] The system staggers trusses on a 12’ module, meaning that on any given floor the trusses were 24’ apart. [2]
Example of true position geometric control defined by basic dimensions and datum features. Geometric dimensioning and tolerancing (GD&T) is a system for defining and communicating engineering tolerances via a symbolic language on engineering drawings and computer-generated 3D models that describes a physical object's nominal geometry and the permissible variation thereof.
A truss is an assembly of members such as beams, connected by nodes, that creates a rigid structure. [1] In engineering, a truss is a structure that "consists of two-force members only, where the members are organized so that the assemblage as a whole behaves as a single object". [2]
Hexadecimal (also known as base-16 or simply hex) is a positional numeral system that represents numbers using a radix (base) of sixteen. Unlike the decimal system representing numbers using ten symbols, hexadecimal uses sixteen distinct symbols, most often the symbols "0"–"9" to represent values 0 to 9 and "A"–"F" to represent values from ten to fifteen.
The ISO 128 replaced the previous DIN 6 standard for drawings, projections and views, which was first published in 1922 and updated in 1950 and 1968. ISO 128 itself was first published in 1982, contained 15 pages and "specified the general principles of presentation to be applied to technical drawings following the orthographic projection methods".
The Weber number appears in the incompressible Navier-Stokes equations through a free surface boundary condition. [3]For a fluid of constant density and dynamic viscosity, at the free surface interface there is a balance between the normal stress and the curvature force associated with the surface tension:
Reference dimensions are provided for a variety of reasons and are often an accumulation of other dimensions that are defined elsewhere [2] (e.g. on the drawing or other related documentation). These dimensions may also be used for convenience to identify a single dimension that is specified elsewhere (e.g. on a different drawing sheet).
The first such bridge was built in steel at Avelgem, Belgium in 1902, following development of the truss form and a method to calculate its strength in 1896 by Arthur Vierendeel. There are many more examples in Belgium, including some built in concrete, mostly designed by Vierendeel's many students from his long career as professor in civil ...
