Question

Figure 1a shows a concrete beam supported by two
solid circular columns. Column AB is made from steel
and column CD is made from aluminium, see the stress
strain graphs in Figure 1b. The concrete beam is
subjected to the load P as shown in Figure 1a.
1. Determine the normal stress in column AB and
column CD. 
2. Determine the relative change in angle of point C
to A in degrees. 

 

Given:

P= 100KN

L1= 3m

L2= 2m

L3= 1m

dAB= 60mm

dCD= 60mm
