Cracking and failure of precast AAC lintels in walls subjected to in-plane vertical loading
Keywords: confined walls, FEM, DIC, precast lintels
This paper presents results from tests on precast reinforced lintels made of autoclaved aerated concrete
(AAC). During tests, load was applied to lintels and masonry available in two variants of a confined wall.
Lintels were tested in two ways: as beams, which along with a masonry wall and a tie were loaded, and additionally
as beams fixed to reinforced concrete cores of a confined masonry wall. The analysis included the
process of cracking and failure of lintels. The Aramis software was used for non-contact measurements of
the model displacements. Failure schemes of lintels were similar, however they differed in a sequence and
localisation of individual cracks. Additional reinforced concrete cores affected the performance of the tie and
horizontal strains. They also improved the design capacity of research models.
