Abstract: Simple formulas for bounding the maximum eigenvalues or computing them exactly are obtained for the uniform strain eight-node hexahedron and the four-node quadrilateral. The development is based ...

Abstract: Dynamic compaction (DC) has an extensive performance record on municipal solid waste (MSW) sites. A database of 56 test sites has been developed and analyzed to garner lessons on the performance of DC on MSW sites. Analysis ...

Abstract: The most efficient hybrid drive philosophy eliminates high-acceleration power peaking and operates as a fully regenerative system (little or no accumulator top-off during station stop). The optimal ...

Abstract: A regenerative drive system for subway trains is mathematically modeled and numerically evaluated for the Toronto Bloor-Danforth Subway Line. The scope of the study dictates a multipaper presentation ...

Abstract: The external system (track, vehicle) for the regenerative drive study is modeled from actual construction drawings and performance specifications. A general duty cycle is constructed and found ...

Abstract: Vehicle energy consumption and savings for the Toronto Bloor-Danforth Subway Line are evaluated. Two vehicle loads are chosen (for this evaluation) indicative of rush-hour and nonrush-hour operation. ...

Abstract: Simple methods for determining the corner crushing strength and the in-plane stiffness of masonry infills are developed. The methods are applicable to structural clay tile, clay brick, and concrete masonry infills and to ...
