Dynamic loads include people, wind, waves, traffic, earthquakes, and blasts. Any structure can be subjected to dynamic loading. Dynamic analysis can be used to find dynamic displacements, time history, and modal analysis. Structural analysis is mainly concerned with finding out the behavior of a physical structure when subjected to force.
The first English language description of the method was by Macaulay. [1] The actual approach appears to have been developed by Clebsch in 1862. [ 2 ] Macaulay's method has been generalized for Euler-Bernoulli beams with axial compression, [ 3 ] to Timoshenko beams , [ 4 ] to elastic foundations , [ 5 ] and to problems in which the bending and ...
Inertial load in numerical models is described in [5] Unexpected property of differential equations that govern the motion of the mass particle travelling on the string, Timoshenko beam, and Mindlin plate is described in. [ 6 ] It is the discontinuity of the mass trajectory near the end of the span (well visible in string at the speed v =0.5 c ).
Dead loads have small load factors, such as 1.2, because weight is mostly known and accounted for, such as structural members, architectural elements and finishes, large pieces of mechanical, electrical and plumbing (MEP) equipment, and for buildings, it's common to include a Super Imposed Dead Load (SIDL) of around 5 pounds per square foot ...
The dynamic response of a structure to dynamic loads (the natural frequency of a structure) is also dependent on its stiffness. In a structure made up of multiple structural elements where the surface distributing the forces to the elements is rigid, the elements will carry loads in proportion to their relative stiffness - the stiffer an ...
Wave loading is most commonly the application of a pulsed or wavelike load to a material or object. This is most commonly used in the analysis of piping, ships, or building structures which experience wind, water, or seismic disturbances .
The macrostructures considered here may be composed of "structural elements" which material presents a "microstructure". Whether searching to limit the stress or the deformation, macrostructure, structural element and microstructure have each, a weight Vρ, when ρ is the volumic weight of materials, in N/m 3, function of the solicitations {F 0} (for "force" in général) applied to them, of ...
Mechanical load is the physical stress on a mechanical system or component [1] leading to strain. Loads can be static or dynamic. Some loads are specified as part of the design criteria of a mechanical system. Depending on the usage, some mechanical loads can be measured by an appropriate test method in a laboratory or in the field.
