Does anyone know the Sds and Sd1 values for Guam and/or Midway Atoll (soil class B)? I am trying to determine the seismicity for these regions. The USGS site notes that Guam is available, but I was not able to generate a value using the building coordinates that I have.
Is anyone familiar with the evolution of the wording (see below) which exempts certain existing buildings from seismic evaluation requirements?
The 2002 version of "Standards of Seismic Safety for Existing Federally Owned and Leased Buildings" (more commonly known as ICSSC RP 6), Section 1.3...
Can someone point me to a sample calc for determining the tension force in an anchor bolt for a base plate subject to overturning forces? I need to determine if an as-built arrangement of four 1/2" diameter anchor bolts is adequate. I already did a quick check using a simple couple to determine...

Can anyone point me in the direction of a detail for temporarily jacking and shoring a steel joist? I am a structural engineer so I can design the components; what I am looking for is a detail to start from. The contractor has pipe staging, so I need a detail from there up.
Thanks for any help...
I am detailing columns and footings for a pre-engineered metal building. This building will sit on a concrete foundation wall with a continuous footing. The plans show a detail at the column locations for a wall bump-out that is two inches bigger, all around, than the base plates for the...
Howdy folks-
I am designing a bridge widening for an historic stone arch bridge in the northeast. We are going to use a stone veneer on both precast concrete and cast-in-place concrete elements on the bridge. Can anyone point me in the direction of A)details for attaching the veneer (should it...
Can anyone point me in the direction of a detail for attaching a temporary jersey barrier to a new, permanent, precast/prestressed beam during phase construction (in this case, a bridge)?
Thanks in advance
Howdy everyone!
I am looking for some guidance on determining the torsional resistance of a drilled shaft. The shaft is not part of a group of shafts; rather, it is the sole supporting element for a traffic signal mast arm. I am trying to determine if an existing shaft is adequate to support a...
I have a database that stores bitmap images (filename and path only) related to specific items in a table. I have a form tied to the table that lists the images that relate to the current item. The form has a command button that allows me to pick images from the list and view them in a separate...
I would like to start using xref'd drawings for multiple details. Is there a way to make dimensions and text uniform for xrefs shown at different scales in different viewports?
My xrefs are drawn 1:1; they will be shown at various scales as needed.
