Given Data:

The Bridge subjected to Lateral Load.

The lateral load F_A is Resisted by diagonal Bracings, Causing additional Lateral Forces, F_B and F_C.

Member AD bends about its minor Axis.

Loads:

F_A : 100 KN

F_B = F_C

a = 0.8m, b = 2.0 m

Now,

Let us calculate the Von mises stresses at

Left Flange tip:

Von mises stress:

Here,

P1 is the First principal stress

P2 is the Second principal stress

P3 is the third Principal Stress.

Now,

For the selected case let us calculate the P1, P2 and P3

P1 = Bending Stress along x axis+ Direct Tensile stress X

P2= Bending Stress along x axis+Tensile stress along Y axis

P3 = Bending Stress along zaxis+Tensile stress along z axis.

Here,

The problem is taken to be two dimensional,

Thus removing the third principal stress and calculating bending stress and Tensile stresses for the X and Y axis.

Bending Stress can be given as:

Where,

M is the Moment

Y is the distance from NA

I is the Moment of Inertia

To calculate I:

Where,

b is the breadth

d is the height of the cross section.

Now,

b = 0.8 m

d = 2 m

I=0.533333 m⁴

Now,

Applying I in the Bending moment equation we get,

Y = 1

I = 0.533333 m⁴

M = Bending Moment

To find Bending moment it is required to carry out the SF and BM diagram,

The beam can be simplified and analyzed
