Polar analysis of beam-columns for aircraft

Creator:: Jones, Walter Richard
Abstract:: The analysis of a member carrying a combination of lateral and axial loads (a "beam-column") is a problem of frequent occurrence in aircraft structural design. This thesis presents the derivation and application of the Polar method, both analytical and graphical. The method was first suggested in Germany, several years later...

Slotted-bolted friction damper as a seismic energy dissipator in a braced timber frame

Creator:: Tjahyadi, Alfred
Abstract:: Friction dampers have been used successfully to dissipate seismic energy in steel and concrete structures. The application is new to timber structures. The objectives of this research were to design a slotted bolted connection (SBC) and evaluate its potential as a passive energy damper in timber brace. The research was...

Evaluation of system effects and structural load paths in a wood-framed structure

Creator:: Martin, Kenneth G.
Abstract:: The objective of this project was to develop an analytical model of a light-framed wood structure using a prevalent structural analysis computer program in order to evaluate system effects and define load paths within the structure, especially under extreme wind events. Simplified modeling techniques and material definitions were developed and...

A force plate for measuring contact forces during dependent transfers onboard aircraft

Creator:: Schafer, Christopher A.
Abstract:: The transfer of air travelers with disabilities between a mobility aid and an aircraft seat is a major source of injury for both the travelers and the airline personnel assisting in the transfer. The risk to both parties might be reduced through the biomechanical study of the transfer task. Such...

Aircraft wing optimization using B-spline models and panel methods

Creator:: Jackson, Danielle Monique
Abstract:: This research investigates shape optimization process, using b-spline models and panel methods, to achieve a high lift to drag ratio for an aerodynamic structure. This research is a proof of concept for further research in aerodynamic shape optimization. The coupled process, involving the design and optimization of a random shape,...

Light-frame versus timber frame : a study in quantifying the differences

Creator:: Malone, Brian P.
Abstract:: The objective of this study was to compare light wood framing and traditional timber framing quantitatively through environmental impact assessment and load path analysis. This research was inspired by a traditional timber frame structure constructed in Vermont in 2011, and the design of structures considered within reflect the general characteristics...

Practical modeling for load paths in a realistic, light-frame wood house

Creator:: Pfretzschner, Kathryn S.
Abstract:: The objective of this study was to develop and validate practical modeling methods for investigating load paths and system behavior in a realistic, light-frame wood structure. The modeling methods were validated against full-scale tests on subassemblies and an L-shaped house. The model of the L-shaped house was then modified and...

Nonlinear finite-element modeling of intercomponent connections in light-frame wood structures

Creator:: Groom, Kevin
Abstract:: Nailed connections have nonlinear load-displacement relations. Modeling these connections in an assembled structure would require a great amount of computational time because of the large number of degrees of freedom. Replacing these connections with energetically-equivalent nonlinear springs reduces the number of degrees of freedom, and leads to computational efficiency in...
