Introduction
TingWall was used on a three
story high research mock-up sponsored by an
industrial group. The aim of the research is to
develop a sensible test method to evaluate the
durability of the sealing properties (air &
water) of a curtain wall system. The mockup was
extensively tested at Architectural Testing
Inc., York, PA from 3/8/06 to 3/21/06. The test
results with theoretical discussions will be
published by the research group at a latter
date. Since Dynamic Water Test is generally
considered as the best simulation of the natural
rainstorm, this Bulletin is limited to present
the results of Dynamic Water Tests without any
discussion.
Results of Dynamic Water Tests
The Dynamic Water Tests were
powered by a propeller airplane engine with the
capacity of generating an equivalent load of 15
psf. The mock-up endured the following
sequential tests in conjunction with applied
loads and structural displacements without water
leakage problem. Other research tests were not
included in the following list.
1. Uniform Load to +30 psf.
2. Dynamic Water Test @ 15
psf.
3. Uniform Loads to +40 psf
and –40 psf.
4. Three cycles of Story
Drifts to L/100 (1.625” to the left and then
to the right).
5. Three cycles of floor
deflection to 0.75” with the last cycle
stayed at 0.75” deflection.
6. Dynamic Water Test @ 15
psf with floor deflection of 0.75”.
7. 1000 cycles of wind loads
(0 to +20 psf) followed by 1000 cycles of
wind loads (0 to –20 psf).
8. 100 cycles of Story
Drifts to L/200 (0.75”).
9. 100 cycles of floor
deflections (0 to 0.375”) with the last
cycle stayed at 0.375” deflection.
10. Dynamic Water Test @ 15
psf with floor deflection of 0.375”.
11. Purposely damaged the
air seal at one of the mullion splice joint
where it was stretched due to the floor
deflection and drilled eight 0.25” diameter
holes on two horizontal panel joints located
at the expected maximum dynamic wind zone.
12. Dynamic Water Test @ 15
psf with floor deflection of 0.375”.
