w88 casino summary
A project is underway at the University of Nevada, Reno to investigate the w88 casino effects of multi-span curved bridges using a 2/5 scale model of a three-span bridge. The model is 145 ft long with an 80 ft radius at the centerline and it rests on four shake tables in the laboratory. The superstructure consists of three steel girders and a concrete deck that is 12 ft wide.
The testing of this model is part of a larger project investigating w88 casino resilience, funded by the Federal Highway Administration.
Six different configurations will be tested to examine different components, including column design (with and without conventional columns), abutment design (with and without backfill behind the abutments), w88 casino isolation (with and without response modification devices), and the effects of live load (with and without trucks on the superstructure).
This specimen was designed by a team of eight graduate students under the supervision of three professors in civil w88 casino.
| Test | Test Focus | Superstructure Type | Substructure Type | Fail w88 casino | Bearing Type | Abutment Type |
|---|---|---|---|---|---|---|
| 1 | Conventional w88 casino | Elastic crossframes | 24" w88 casino (Set A) | Yes | w88 casino | w88 casino pounding |
| 2 | Live load | Elastic crossframes | 24" w88 casino (Set B) | Yes | w88 casino | w88 casino pounding |
| 3 | Base isolation | Elastic crossframes | 24" w88 casino (Set C) | Yes | Elastic isolators | w88 casino pounding |
| 4 | Hybrid isolation/ductile crossframes | Ductile crossframes | 24" w88 casino (Set D) | w88 casino | Hybrid isolators | w88 casino pounding |
| 5 | Abutment pounding | Elastic crossframes | 24" w88 casino (Set D) | Yes | w88 casino | Pounding |
| 6 | Rocking w88 casino | Elastic crossframes | Rocking w88 casino | Yes | w88 casino | w88 casino pounding |
Currently, there are no design regulations on horizontally curved bridges and the data from this project will provide new insight on their behavior under w88 casino loading. The results of the research will be incorporated into future industry design codes. Ultimately, this will help structural engineers design curved bridges to withstand the effects of strong earthquakes.
