ROSA P serves as an archival repository of USDOT-published products including scientific findings, journal articles, guidelines, recommendations, or other information authored or co-authored by USDOT or funded partners.
As a repository, ROSA P retains documents in their original published format to ensure public access to scientific information.
The research completed under this project was directed toward the development of basic analytical methods using computer simulation for highway bridges, pavements, and similar structures. This report presents a summary of the major computer developments made during the course of the project. Each development is described briefly and those that are of continuing importance are explained in more detail. The three major areas of development that are included are for line members, two-dimensional plane frames, and plates and grids. These areas encompass most of the structural problems encountered by design engineers. Research investigators in other areas and engineers of the Texas Highway Department are currently using a number of the completed developments in their daily work. Experimental and other analytical comparisons have shown that very satisfactory results can be obtained and thus lend confidence to application of the computer programs.
A discrete element analysis which considers geometric, material, and support nonlinearities of statically loaded plane frames is developed. A computer...
A computer program for the direct linearly elastic analysis of complex bridge bents and other highway structures has been developed and is reported he...
