Well done, Mark! I'm am so sick and tired of people harping on the
expansion joints as sources of structural failure on the Titanic as
well as other ****ps. Expansion joints are part of the
SUPERSTRUCTURE. Note the nomenclature. They are a part of a section
of the ****p which contributes minimal structural strength, if any, to
the ****p itself. "Super"--over or above--"structure."
As a lay explanation of the purpose of an expansion joint, Mark, your
comment is spot-on!
All the best,
Daniel Allen Butler
