considered as the originator of the theory of structures
Galileo Galilei
ushered a new era of structural engineering in which analytical principles of mechanics and strength of materials would have major influence on the design of structures
Galileo Galilei
developed the law of linear relationship between the force and the deformation of materials
Robert Hooke
formulated the laws of motion and developed calculus (foundational mechanics)
Isaac Newton
formulated the principle of virtual work
John Bernoulli
developed the theory of buckling columns
Leonhard Euler
presented the analysis of elastic bending of beams
C. De Coulomb
published a treatise on elastic behavior of structures (1st textbook on modern theory of strength of materials) in 1826.
L.M. Navier
formulated the three-moment equation for the analysis of continuous beams
B.P. Clapeyron
presented the method of consistent
deformations and the law of reciprocal deflections
J.C. Maxwell
developed the conjugate beam method for calculation of deflection and Mohr’s circle of stress and strain
Otto Mohr
formulated the theorem of least work
Alberto Castigliano
developed the area moment method
C.E. Greene
presented a principle for constructing an
influence line
H. Muller-Breslau
developed the slope deflection method (the precursor of matrix stiffness method)
G.A. Maney
developed the moment distribution method in 1924 (most widely used by structural engineers between 1930 to 1970)
provided significant understanding on the behavior of statically indeterminate frames

STRUCTURAL ENGINEERING
The prediction of the performance of a
given structure under prescribed loads
and/or other external effects, such as
support movement and temperature
changes.
It is an integral part of any
structural engineering project, its function being the prediction of the performance of the proposed structure.
Structural Analysis
engineers began applying
Mechanics (Math and Science) in designing structures
Mid 17th Century
structures were designed by trial and error using rule of thumb based on past
experience
