m The analogy of "bones and muscles" makes little sense. Structural Engineers provide designs for beams and columns (bones) as well as the connections thereto (joints). What is muscle doing in this analogy?

'''Structural engineering''' is a sub-discipline of [[civil engineering]] in which [[structural engineer]]s are trained to design the 'bones and musclesjoints' that create the form and shape of human-made [[Structure#Load-bearing|structures]]. [[Structural engineers]] also must understand and calculate the [[structural stability|stability]], strength, [[structural rigidity|rigidity]] and earthquake-susceptibility of built structures for [[building]]s<ref>[http://www.fao.org/docrep/015/i2433e/i2433e04.pdf FAO online publication] {{webarchive|url=https://web.archive.org/web/20161119191121/http://www.fao.org/docrep/015/i2433e/i2433e04.pdf |date=2016-11-19 }}</ref> and [[nonbuilding structure]]s. The structural designs are integrated with those of other designers such as [[architects]] and [[Building services engineering|building services engineer]] and often supervise the construction of projects by [[contractors]] on site.<ref name = IStructE/> They can also be involved in the design of machinery, medical equipment, and vehicles where structural integrity affects functioning and safety. See [[glossary of structural engineering]].
 
Structural engineering theory is based upon applied [[physics|physical laws]] and [[empirical]] knowledge of the structural performance of different materials and geometries. Structural engineering design uses a number of relatively simple structural concepts to build complex [[structural system]]s. Structural engineers are responsible for making creative and efficient use of funds, structural elements and materials to achieve these goals.<ref name="IStructE">{{cite web|url = http://www.rmg-engineers.com/what-is-a-structural-engineer/|title = What is a structural engineer|access-date = 2015-11-30|date = 2015-11-30|website = RMG Engineers|url-status = live|archive-url = https://web.archive.org/web/20151208052438/http://www.rmg-engineers.com/what-is-a-structural-engineer/|archive-date = 2015-12-08}}</ref>
