Bank of Newport - Structural Restoration Project,
Newport, RI
Northeast
Engineers & Consultants performed a structural
investigation of the historic masonry building,
constructed in 1920. The investigation found the
water proofing of the structure had failed. This
led to deterioration of the mortar between the
brick work and the significant deterioration of
the embedded steel beams supporting major spans
and loads. Large marble panels weighing several
thousand pounds were fracturing under the redistribution
of stresses caused by the weakening of the structural
steel elements within the building.
NE&C devised a plan to construct a bracing
system to hold the weakened masonry areas securely
while further destructive inspection could be
achieved. This was particularly important since
the bank continued its daily business and the
patrons had to be protected against any stonework
falling from the building. The destructive inspection
revealed further complication with the building.
The loads were calculated for each bearing point
in order that it could be supported during repairs.
A structural restoration program was developed
to repair most of the structural features. The
overall water proofing deficiencies are being
corrected.
In the spring of 2000, NE&C, in a cooperative
effort with the masonry company, will disassemble
sections of the front end of the bank building
and replace the major structural steel supporting
the roof, masonry fascia, and historic marble
panels.
