FRP Truss Precast
FRP Truss – Precast
Low-thermal conducting fi ber reinforced truss for
precast concrete “sandwich” panels
This FRP Truss for precast concrete panels develops strength and rigidity from a fi ber reinforced design. Foam
insulation is placed between lengths of FRP Truss and sandwiched between the inside and outside concrete
panels to provide the following advantages:
• Fiber reinforced material improves the thermal effi ciency of panels and reduces cold bridging.
• Supports all working loads, including stripping, handling, transportation, installation, and service.
• Shape provides composite action between the inside and outside concrete panels.
• Durable and corrosion resistant material is 2.5 times stronger than steel and does not stain.
• Adapts to locally available foam insulation materials.
FRP Truss is easy to install. The truss can be
pre-set or wet set with foam insulation. The
insulation is placed between the lengths of
truss, then sandwiched between the inside
and outside concrete panels.

A panel was installed in a vertical position and
secured against movement by anchors and crossbars
through the force fl oor. The mounting loops were
welded to the metal uprights. The internal layer was
also pinched. A uniformly distributed load on the outer
layer of the panel was transferred from the hydraulic
jack through a rigid metal plate. Results:
• The maximum load applied to the outer layer
of the panel was 5.8 K/ft. Cracks and signs of
destruction of the panel were not detected.
• At a design load of 993 lbs/ft the actual mutual
displacement of the outer layer relative to the inner
layer was 0.0196”.
• At the maximum load of 5.8 K/ft, the displacement
of the outer layer was 0.2”.
Fire Resistance Test
A load of 548 lbs/ft was applied to the outer layer of
the panel for 30 minutes. A fi re load was applied to
the inner layer of the panel for a further 30 minutes.
After exposure to fi re, the product was kept under
load for 24 hours to cool to room temperature. At the
fi nal stage of testing, a load was applied to the outer
layer of the panel in increments of 13.7 lbs/ft before
failure. Results:
• The time of occurrence of the limit state for loss of
integrity (E) during the test is not reached.
• The time of occurrence of the limit state of
the carrying capacity (R) during the test is not
reached.
• The time of occurrence of the limiting state of loss
of thermal insulating ability (I) during the test is not
reached.
• The maximum load applied to the outer layer of
the panel after the fi re impact was 4.83 times
higher than the benchmarks, amounting to 2.6 K/ft.
• The fi re resistance limit of a panel is at least REI
30.
