Michell structures are structures that are optimal based on the criteria defined by A.G.M. Michell in his frequently referenced 1904 paper. [1]Michell states that “a frame (today called truss) (is optimal) attains the limit of economy of material possible in any frame-structure under the same applied forces, if the space occupied by it can be subjected to an appropriate small deformation ...
Warren truss – some of the diagonals are under compression and some under tension. In structural engineering, a Warren truss or equilateral truss [1] is a type of truss employing a weight-saving design based upon equilateral triangles. It is named after the British engineer James Warren, who patented it in 1848.
[10] [6] CLS is planed and fished with eased or rounded edges. [9] [11] CLS timber is commonly graded at two strengths, C16 or C24. [9] C24 is the stronger and is typically more expensive. [10] It is often pressure treated and may also be treated with pesticides to stop insect and fungal growth. [5]
[6] [a] Sometimes a Palladian truss is defined as a compound truss with a queen post and king post truss in the same assembly. [7] The queen post truss and the king post truss may be combined, by using the straining beam of the queen post truss as the tie beam for a king post truss above. [8] Such combinations are known as compound trusses.
A truss element can only transmit forces in compression or tension. This means that in two dimensions, each node has two degrees of freedom (DOF): horizontal and vertical displacement. The resulting equation contains a four by four stiffness matrix.
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]
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]
The M1074 Joint Assault Bridge System (JAB, JABS) is an American armored military engineering vehicle based on the Abrams M1A1 main battle tank chassis. [8]: p.154 The M1074 was designed by Leonardo DRS for the U.S. Army and Marine Corps to provide deployable bridge capability for units engaged in military operations.
