What is Structural load?
[[File:DEAD lOAD.jpg|thumb|right|250px|{{Center|Structual load is the weight a structure has to carry, here a building}}]] '''Structural loads''' or '''actions''' are [[force]]s, [[Deformation (engineering)|deformations]], or [[acceleration]]s applied to a [[structure]] or its [[Structural_engineering#Structural_elements|component]]s.<ref>{{cite book|title=ASCE/SEI 7-05 Minimum Design Loads for Buildings and Other Structures|year=2006|publisher=American Society of Civil Engineers|isbn=0-7844-0809-2|pages=1}}</ref><ref>{{cite book|title=Eurocode 0: Basis of structural design EN 1990 |year=2002|publisher=European Committee for Standarization|location=Bruxelles|chapter=1.5.3.1}}</ref> A [[wikt:load|load]] is the amount of [[weight]] a [[wikt:structure|structure]] has to carry. Loads cause [[stress (physics)|stresses]], [[deformation (engineering)|deformations]], and [[wikt:displacement|displacement]]s in structures. [[Structural analysis]] is the [[wikt:calculation|calculation]] of the effects of loads on physical structures. Excess load or overloading may cause [[structural failure]]. This is a [[wikt:consideration|consideration]] in the [[design]] and [[construction]] of a structure. Mechanical structures, such as [[aircraft]], [[satellite]]s, [[rocket]]s, [[space station]]s, [[ship]]s and [[submarine]]s, have their own particular structural loads and actions.<ref>{{cite book|title=Mark's Standard Handbook for Mechanical Engineers|publisher=McGraw-Hill|isbn=0-07-004997-1|edition=10th|editor=Avallone, E.A., and Baumeister, T.|pages=11–42}}</ref> In a vehicle, especially trucks, the [[chassis]] is designed to carry the structural load.<ref name=SimanaitisR&T>{{cite web |url=http://www.roadandtrack.com/new-cars/car-technology/news/a17656/from-the-carriage-trade-to-carbon-fiber/ |title=From the Carriage Trade to Carbon Fiber |author=Dennis Simanaitis|date=5 October 2011 |website= |publisher=Road & Track magazine/Hearst Communications, Inc. |accessdate=24 May 2015}}</ref> In many [[car]]s [[unibody]] construction is u
