Tenders are invited for Cleaning Of Alternate Uplift Pressure
Drainage Holes In Foundation Gallery Of Indira Sagar Dam, Narmada Nagar, Distt.
For a gravity dam of 100 m, the foundation uplift pressure
is approximately 20% of the dam weight under normal reservoir level and is therefore the main load for concrete gravity dams which directly influences the dam stability [10, 11].
It was observed that the section modeled by the Consultant (NESPAK, 2007) without considering drainage arrangement, the uplift pressure
at point A and B (Fig.
When added to the underside of the roof deck InsulStar enhances the connection strength of the existing roof system, which helps mitigate the effects of wind uplift pressure
, according to the company.
I applied approximately seven pounds of uplift pressure
on the newly bedded forend tip and tested several five-shot groups using the same loads as those used prior to the work performed on this rifle.
In each case, FM Approvals testing must be done with simulated wind uplift pressure
with the module attached to a test frame using a pleated air bag and with tensile loading of the fasteners/clips.
24 m/s), there was a high effect of the uplift pressure
, which balanced the downward force from the vehicle weight, water weight, and slab weight.
It also pointed out that the equipment installed by the Tamil Nadu government to measure the uplift pressure
did not yield expected results, he said.
The test showed that water--probably from irrigation--had swelled the clay soil, causing uplift pressure
and the observed cracks.

In reality, the wind uplift pressure
is dynamic, and the response of the roofing structure is dynamic as well.
THE WIND-UPLIFT TEST: In accordance with Factory Mutual Protocol, FMRC 12/24 wind-uplift pressure
test Appendix D and the Dade County roofing protocol PA-114-95 Appendix D for simulated uplift pressure
resistance of adhered roof systems assembly.
