Q1 - Modern Steel Construction

of expansion bolls between face plates
and the eXisting concrete structure was
devised As with the design of the strucetural
steel elements. careful analysIs determined
the level 01 shear and tenSion In
each boll The size and required embedment
length of each boll IS specilled accordingly
With discrete connection pOints at each
eXlsllng exterior column, minimal demolition
work IS reqUIted at the eXlstmg exterior
wall The erection sequence calls for all
the column collars to be Installed prior to
erection of trussed brackets and lloor
beams There IS mlnlmat disruption to the
eXisting structure With thiS concept, Since
all of the major steel elements are externally
applied to the bUilding After the
structural steel was Installed and the new
space In place. the old exterior wall was
removed and the deSired enlargement of
the eXisting lloor space created
As previously mentioned, one of the
chief advantages of the trussed scheme
over the roof cantilever scheme IS that the
load transfer path IS more direct New lloor
and roof loads are channeled Into the ex­
Isting columns at their correspendlng levels
(or lower) so that the eXisting columns
resist decreaSing loads as they ascend.
Each column and fOOling In the eXisting
structure affected by the new construction
has adequate reserve strength to safely
suppert Ihe new loads Siruciural steel
construction was the only solution-Since
light weight, durablhty, erectablhty and
economy were essenllals for thiS project
Conclusion
The Stoneman BUilding Includes medlcall
surgical and obstetrlcat nursing umts, diagnostic
cardiology, clinical neurophYSIology
and dialYSIS Total cost lor these renovations
and new construction IS
$13,635,000 Bedrooms deSigned to resembte
the new ones In the Reisman Build­
Ing Will be generated by Stoneman's lateral
expansion The lateral expansion
becomes the locus for the new pallent tOIlet
rooms, a loungel sllllng area for VIsitors
and a generous expansive Window open­
Ing affording a view over Boston's Fenway
Park. Pallents In each room Will lace oakpanelled
walls With Integrated ward robes,
balanced by strongly organized color sclutlons
lor repese The room IS deSigned
to increase the patient's feeling of wellbeing
at Boston's Beth Israel Hospital
the first hospital to create a Patient Bill of
Rights.
As a result 01 the combined new addition
and total renovallon, Ihe Stoneman pallent
care uOlis are brought up to the standards
of Ihe new Reisman BUilding, and Will pro­
Vide patlenls Ihe same Inllmale quality and
Intenor enVIronment The solution also extends
the life span of the eXisting bUilding
Into one equal to that of the bUlldmg recently
constructed The architect and
structural engineering team have once
again shOwn Ihat structural steel construction
prOVided the best pesslble solution to
a complicated expanSion problem al a
large medical center 0
