TingWall Performance under Dynamic Water Tests


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”.
