The architect's report also points out:'It should be noted that the church is in an area which has a history of building movement and settlement, and the church shows evidence of this in cracks through masonry joints
and units and misalignment of building elements.'
The developed interface model consistently simulates the behavior for masonry joints
, which dominates many modes of failure of the masonry.
Then they fixed up crumbling masonry joints
on a section of the canal site.
Crumbling masonry joints
start out ugly, and then things get uglier fast--bricks come loose, water seeps behind the wall and bees make their homes in the mortar holes.
It is based on observed behavior of masonry joints
and is expressed in terms of the confining stess ([sigma]) and the inelastic shear-slip ([v.sub.p]) as:
The total values of permanent deformations (strain) of monitored vault arches tend to reach higher values in time (approx 0,4 to 0,7 mm/year), and result in a gradual degradation (cracking in masonry joints
) and disintegration of the stone masonry (Fig 11 b).
Grinding of the old caulking material to remove it from the building masonry joints
could also have contributed to the finding of soil contamination.
When constructing new masonry walls intended for stucco surfacing or veneer, install galvanized ties every 12 inches in the masonry joints
when the wall is constructed.
For example, the rusting of a steel beam, corrosion of a cast iron pipe, erosion of mortar between masonry joints
and weathering of a roofing membrane all progress at a relatively uniform rate.
Since they are non-corrosive, extremely tear resistant and stick reliably to almost anything, they're a good choice for joints between dissimilar materials, such as metal-to-masonry joints around chimneys, wood-to-concrete joints at the sill plate, and masonry joints
in driveways and concrete slabs.
The infiltration was caused by deteriorated 50-year old masonry joints
