Sažetak
Determination of the bearing capacity of a structure is very valuable, not only as a simple control of structural bearing capacity, but also as a significant basis and factor in designing of structures. Limit load of structures determined by application of the limit analysis is one of the indicators of bearing capacity of structure exposed to the action of proportional load. When the structure is exposed to the action of variable repeated load, the limit theorems do not yield the adequate solutions, thus the adaptation theorems which made safe limit load determination possible were developed simultaneously. By applying the limit and shakedown analysis in this paper structural analysis of frame structures with different degrees of static indeterminacy was carried out. Also displayed is the difference between the values of failure forces depending on the character of load and ratio of height and width of frame in order to assess justification for application of the shakedown method in the analysis of the limit bearing capacity of the frame structures.
