In this particular example, the cost is $250,000, which includes reinforcement of the steel spandrel beam
, masonry reconstruction and replacement of coping stones.
To correct this, one course of brickwork was removed above every spandrel beam and flashing was replaced, with weep holes, to ensure water in the wall system would be led away from the building.
For one, many concrete buildings have exposed spandrel beams or columns as part of their design vocabulary, leaving the materials subject to the wear and tear of the elements.
A major condition assessment was undertaken by WASA, evaluating the reinforced concrete structures with exposed spandrel beams at every floor, brick panels composed of eight-inch square bricks between spandrels, and aluminum frame windows.
Hence, the diagonal members must be in compression while the spandrel beams
are in tension.
The Hall Partnership solution involved the creation of stainless steel armatures at each floor suspended by 2" diameter clevis / rod assemblies and expansion bolted back to the existing concrete spandrel beams
so that each floor supported its portion of the chimney face brick independently; similar to a cigarette girl's tray.
The Rookery features cast-iron columns, wrought-iron spandrel beams
, a striking oriel staircase and Italian marble floors and wainscoting.
Torsional Strengthening of Spandrel Beams
with Fiber-Reinforced Polymer Laminates, Journal of Composites for Construction ASCE 8(2): 157-162.
A unique cable-suspended marquee, inspired by the Brooklyn Bridge -- an extension of the entry vestibule -- was fabricated from re-used spandrel beams
In the 20 years since its construction, the multi-building complex had been experiencing an acute series of concrete problems along the seven miles of exposed concrete spandrel beams and balcony fascias.
WASA performed a major condition assessment to evaluate the reinforced concrete structures, including exposed spandrel beams at every floor and brick panels composed of eight-inch square bricks between spandrels and aluminum frame windows.
