Thermal Response Of A Composite Bridge Structure, David John Wisch
Thermal Response Of A Composite Bridge Structure, David John Wisch
Masters Theses
"This experimental investigation was conducted as an intermediate study to verify and substantiate a prior theoretical study for possible utilization toward development of rational bridge design criteria. The objectives of the study were to construct and instrument a 15 ft - 15 ft (4.6 m- 4.6 m) two-span, composite design, laboratory structure, to subject the structure to thermal loading, and to correlate the experimental temperature distributions, strain distributions, and deflections with those obtained from the theoretical study. Infrared heat lamps were used to obtain steady-state thermal loading.
Three theoretical cases were considered for strain calculations: a) both the slab and …

Removal Of Organic Chemical Contaminants By Granular Activated Carbon., Garry Reinhold Aronberg
Masters Theses
"The purpose of this investigation was to evaluate the effectiveness of GAC* filtration in removing organic chemical contaminants from drinking water, and to determine whether the T.O. No. of the treated water could aid in the routine monitoring of the GAC filters.
Two pilot filters containing 18-in. (45.7-cm) deep GAC beds were installed at water treatment plants in Jefferson City and St. Louis County, MO; both plants treated Missouri River water. A bituminous coal-base (large surface area, small pore volume) and 2 lignite coal-base (small surface area, large pore volume) carbons were tested at 2 and 5 gpm/sq ft (81.4 …
Dynamic Pullout Resistance Of Anchors Buried In Dry Sand, Chris John Veesaert
Dynamic Pullout Resistance Of Anchors Buried In Dry Sand, Chris John Veesaert
Masters Theses
"The vertical pullout resistance of buried anchors subjected to dynamic loading was investigated by means of a laboratory model study. A dry uniformly graded sand, compacted by vibration to 92% of its relative density, was used as the test medium. Tests were performed in a 24-inch square tank using 3.0 and 5.0-inch diameter half and full-anchors. The anchors were tested at depths ranging from 5.0 to 21.0 inches.
It was assumed that the dynamic failure mechanism of earth anchors was the same as the static failure mode, and not distinct behavior. Thus static tests, i.e., tests using a constant strain …
