4. Stress and deflection analysis of short and long beams with different end conditions and cross-sectionssubjected to different loading conditions (i.e., point load force & moment, distributed load etc) using !"software

4.1 Problem Description:

Introduction:#n this e$ample you will learn to use the %eam element in "S'S.Physical Problem: Structural analysis of the steel member shown below.

he structure is made up of beams. 'ou may recall that a beam is a structural element whose length isery large compared to the other two dimensions.

Units:*se MPA. units+'

Geometry:as shown in figure. Material:"ssume the structure is made of steel with modulus of elasticity ! $/0

123a and 3oisson

ratio 0.5

Boundary conditions: "ll the 6+s are constrained at the right end.

Loading:*6 is applied at first section 00 7m. he point load is in the negatie ' direction. he loadalue is /000 . and moment alue at right side is 1 8-m

Objectie:o determine deflections at the points of application of load.o determine the ma$imum stress in the structure.Shear force and bending moment

'ou are re9uired to hand in print outs for the aboe. !igure
