Column-Supported Embankments: Full-Scale Tests and Design Recommendations
… test procedures are described. A total of 5 CSE tests were conducted with 2 ft diameter columns in a square array. The first test had a column center-to-center spacing of 10 ft and the remaining four tests had center-to-center spacings of 6 ft. The Adapted Terzaghi Method of determining the …

Shear and Peel Stresses at the Interface between Hollowcore Slabs and the Topping Concrete
… surface finishes. Three types of tests were performed: pull-off, push-off and full-scale. They provided an overall understanding of the interfacial shear and peel behaviors at the interface between hollowcore slabs and the topping concrete. The tested slabs were found to sustain …

Uplift loaded standing seam roof systems
… standing seam roof system. Four sets of full-scale tests were conducted and their results were analyzed along with previous results (Anderson 1991). It was found that by normalizing the data, a reduction factor could be established for each test set configuration. This reduction factor …

Web crippling of hot-rolled beams at stiffened-seat connections
… of hot-rolled sections. In addition, three full-scale tests were conducted on steel-concrete composite beams to verify the accuracy of the proposed equation. Finally, the current web crippling equations and the proposed equation are compared for all available end web crippling data, and …

Low-Speed Maneuverability, High-Speed Roll-Stability, and Brake Type Performance of Heavy Truck 33-ft Double Trailers
… the methods and analysis of extensive physical tests and simulation conducted by the Center for Vehicle Systems and Safety (CVeSS) at Virginia Tech on the maneuverability, roll-stability, and brake type performance of 33-ft double trailers. Little literature exists for 33-ft doubles because they …

Numerical Investigation of Cleavage Fracture in Welded Connections of Steel Moment Resistant Frames
… backup bars). A set of previously conducted, 15 full-scale tests on T-connections of the pre-Northridge design (A36 beams, A572 columns, E70T-4 welds, backup bars left in place) provide fracture moments to calibrate parameters of the Weibull stress model. This study initially considers …

Full scale study of chemically enhanced primary treatment in Riviera de Sao Lourenco, Brazil
… CEPT plants, special attention is paid to the full-scale study and analysis of the CEPT upgrade at Riviera de Sao Lourenco, Brazil. This plant conducted full-scale tests of both "prepond" and "in-pond" CEPT. This thesis compares the advantages and disadvantages of "prepond" and "in-pond" CEPT, …

A Low Cycle Fatigue Testing Framework for Evaluating the Effect of Artifacts on the Seismic Behavior of Moment Frames
… structural systems with artifacts. For instance, full-scale testing of moment resisting connections is expensive which makes it economically infeasible to experimentally examine the wide range of possible artifact types, artifact locations, and structural configurations. A framework has been …

Dynamic identification of the Augusta hybrid base isolated building using data from full scale push and sudden release tests
… subjected to a series of push and sudden release tests in March 2013. The Augusta isolation system is hybrid, consisting of 16 High Damping Rubber Bearings (HDRB) and 20 Low Friction Sliding Bearings (LFSB). The tests were characterized by a long quasi-static phase, where the building was pushed …

Reinforced concrete columns of variable cross section
The results of a series of 19 full scale tests carried out on pin-ended reinforced concrete columns are reported. The columns tested had either tapered rectangular sections along the length or octagonal cross sections. All columns, except the last 6, were subjected to uniaxial eccentricities at one …

Development of Alternative Crab Claw Processing Systems to Minimize Environmental Impact
… the crab claw meat and shell. These methods, in full scale tests, produced meat yields comparable to that of the brine solution and improved the overall taste of the meat product. However, the effluents had significantly higher BOD5 concentrations. Another alternative to the Harris Claw machine, …
