LOAD CARRYING CAPACITY OF HYBRID COMPRESSED STEEL ELEMENTS

摘要

The application of cross-section material combinations can be advantageous also in the case of compressed steel elements, particularly those with slender webs. Realised experimental and theoretical investigation creates for that necessary premises. In compressed combined steel elements the elasto-plastic postcritical load carrying capacity of the thin webs should be also utilised in dependency on the material properties and load carrying capacities of bordered flanges. The proposed calculation conception for the determination of the local elasto-plastic postcritical load carrying capacity of hybrid compressed steel elements with thin webs is safe and suitable for practical applications. The proposed approximate calculation procedure for the determination of global load carrying capacity of hybrid compressed steel elements with thin webs can be also considered as reliable and applicable in practice.
