The Rankine-Merchant Load and its Application,ads of frame structures are discussed. The concept of deteriorated critical loads is explained, and its value in obtaining an understanding of the criteria for failure of structures in the elastic-plastic range demonstrated by reference to examples. The use in the Rankine-Merchant formula of the two

The Southwell and the Dunkerley Theorems,ained by combining the load factors of subproblems in different ways. If the critical load factors are directly added, then the formula is called a . type formula. If the reciprocals of the critical load factors are added, then the formula is called a . type formula.

Practical Examples,lity. After three simple examples several more complex problems are discussed involving columns, plates, frames, arches, in which these theorems can be usefully applied. Finally, practical problems associated with the stiffening of buildings and the lateral stability of beams are treated.

The Southwell and the Dunkerley Theorems,Papkovich theorem, Kollár conjecture, Melan theorem), and show, where possible, the conditions under which the results are on the safe side. The proofs are given in mathematical way, based on the relationships for eigenvalues of linear operators in Hilbert space. The theoretical results are illustrated by examples.
