Cracking and failure of precast AAC lintels in walls subjected to in-plane vertical loading

Keywords: confined walls, FEM, DIC, precast lintels
Abstract:

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.
