RE: Concrete Reinforcing Choices

[Subject Prev][Subject Next][Thread Prev][Thread Next]


From my office window I do not see a lot of high-rise buildings going up in Irvine and very few if any are made of concrete except in the footings and floors.  Can you get the name and location of these "high-rise buildings in Irvine"?

Well MMFX claims they are using it in a pair of high-rises in Irvine,
CA. Do you have the most up to date ICBO?

As noted, the ICBO report ER-5930 states that MMFX "must not be used in
seismic-resistant reinforced concrete members". Two questions:

1. Does anyone know why this limitation was put on this material? The
site claims the ductility of the material is one of its benefits.

2. For a concrete structure designed per the IBC, is there anywhere in
US where at least a portion of the structure does not require "seismic
resistant reinforced concrete members"?

Interesting stuff but one problem (at least around here) is that it is
allowed in seismic applications and is not weldable.

Someone recently asked about how to design with FRP materials.  If the
is corrosion, check out  Information on the web site
in ICBO ER-5930 suggests design according to the UBC, ACI 318, and
in the Evaluation Report where a corrosion resistant alternative to ASTM
A615 Grade 75 is desired.  This design process may be more familiar to
practicing engineers, and field fabrication is possible.  There may be
benefits too.  I saw this material at the Structures Congress in
and it looks promising.  Since my digest subscription to the list did
come through last night, someone else may have suggested this already
without my seeing it.
