Dynamic Timoshenko Beam-Columns On Elastic Media, Franklin Y. Cheng, Chris P. Pantelides

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Differential equations, stiffness coefficients, and fixed-end forces are formulated for a Timoshenko beam-column on an elastic foundation subjected to lateral time-dependent excitations and static axial loads. The theoretical formulation includes shear and bending deformations as well as rotatory inertia, with emphasis on two approaches. The two approaches differ in terms of the assumed shear component of the static axial load on the cross section. The first approach is based on the assumption that the shear component of the axial load is calculated from the total slope; in the second approach, the shear component of the axial load is calculated only …

Static Timoshenko Beam-Columns On Elastic Media, Franklin Y. Cheng, Chris P. Pantelides

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Two approaches are used to derive differential equations, stiffness coefficients, and fixed-end forces for the analysis of structural systems composed of Timoshenko beam-columns that may be supported by an elastic foundation. The analysis is for the evaluation of the critical static axial load and buckling mode-shapes of a structure with consideration of elastic media, bending, and shear deformations. The two approaches differ in terms of the assumed shear component of the static axial load on the cross section. The first approach is based on the assumption that the shear component of the axial load is calculated from the total slope, …

Homestead Neighborhood And The Oregon Health Sciences University Background And Recommendations Report, Thomas Bizeau, Jim Crawford, Barton Delacy, Yousef Massoudifar, Tom Mcconnell, Foziah Rahman, Ezzat Rassoli, Barbara Sochacka

Master of Urban and Regional Planning Workshop Projects

The Homestead Neighborhood is located in southwest Portland. It was first studied as part of the Marquam Hill Plan in 1977. Since that time two major health providers, the Shriners and the Veterans Administration,have built new facilities on the hill. The Oregon Health Sciences University is now poised and ready for major expansion of its medical schools, hospital and research facilities. Meanwhile, area residents and property owners, have voiced concerns about increased traffic, and building density.

Oregon Health Sciences University (OHSU) contracted with the School of Urban and Public Affairs at Portland State University to draft a comprehensive neighborhood plan, …
