VARIOUS SPECIFICATIONS REGARDING STABILITY PROBLEMS IN STEEL STRUCTURES IN FORCE TO-DAY

VARIOUS SPECIFICATIONS REGARDING STABILITY PROBLEMS IN STEEL STRUCTURES IN FORCE TO-DAY
Comparison of specifications regarding stability problems in steel structures in different countries reveals widely differing bases for dimensioning compression members. This paper briefly specifies failing stresses, allowable working stresses and factors of safety as a function of the slenderness ratio in an axially loaded compression member of steel St 37. It is obvious that allowable
buckling stresses and safety factors in different countries vary up to about 30 percent in the non-elastic and about 80 percent in the elastic range. This fact exercises considerable effect upon the economy of steel structures. Great discrepancies between individual specifications reveal the advantages implicit in uniform European specifications very clearly. The costly, but very necessary, research work involved in solving the more complicated stability problems, might conceivably be shared systematically between the States of the European Convention of Association of Steel Structures and would therefore prove far more effective.
