Series No. 1: CHAPTER 2: CALCULATION OF PARTS REQUESTED IN SIMPLE
COMPRESSION
EXERCISE 1:
Calculate  the  buckling  resistance  of  a  double-articulated  column  with  HEA320  section  in
S235 steel, of length L0= 4.5m and loaded in axial compression equal to Nsd= 2500 KN. The
support conditions are presented in the figure below :(Figure 1)
1) Calculate the elastic critical load Ncr,y and Ncr,z
2) Check the buckling stability of the column according to EC3, CCM97.
EXERCISE 2:
Calculate  the  buckling  resistance  of  a  column  doubly  embedded  according  to  (y.y)
and doubly articulated according to (z.z) with a section in HEM450 in S235 steel, of
length L0= 6m and stressed in axial compression equal to Nsd= 3000 KN.
1) Check the buckling stability of the column according to EC3, CCM97.
EXERCISE 3:
What  is the maximum load that an 8m high HEB240 S235 steel post can support, embedded
at the head and bottom in both directions.
EXERCISE 4:
Calculate  the  buckling  resistance  of  a  column  bi-articulated  along  y.y  and  embedded
articulated  along  z.z  with  HEB  section  in  S235  steel,  length  8m  and  loaded  in  axial
compression equal to Nsd = 2000KN,
