Criser Troutman Tanner provided full structural engineering design
services for this new 525-student, K thru 5th grade, 61,059 sf
elementary school. Structural services consisted of designing a
one-story structure with a mechanical mezzanine in the center of the
building. The classroom wings, as well as the center highbay hub, were
designed with a combination of steel frames, steel roof joists and
exterior cold-formed steel stud curtain walls with cold-formed, strap
cross-bracing lateral resisting systems within the stud walls,
concentric steel cross-bracing along the corridor between steel columns
and masonry shearwalls at the firewalls. The highbay multipurpose room
and mechanical rooms were designed with load-bearing masonry
construction and masonry shearwalls. Shallow foundation systems,
consisting of isolated spread footings and continuous wall footings,
were utilized. The building was designed for 135 MPH wind speed
pressures and associated seismic site class D forces with a response
coefficient of 3.0 for systems not specifically detailed for seismic
resistance. This building was a site adaptation of a building design
that had been used twice previously; however, an increase in wind
pressures and seismic requirements as well as some modifications to
canopies to match the adjacent middle and high school buildings was
required.
Full
construction administration services were also provided.
In
addition, special inspection services were provided directly to the Owner by
CTT as the Structural Engineer agent to the Special Inspector, ECS, Ltd. |
