  • 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...

  • Load sharing and system factors for light-frame wall systems

    Creator:
    Yu, Guangren
    Abstract:
    A considerable amount of research has focused on load-sharing and system effects in repetitive-member wood floor systems subject to transverse loading. However, relatively few studies have been conducted to investigate load-sharing and system effects in repetitive-member wall systems which may be subject to combined transverse and gravity (vertical) loading, and...

  • Cockpit task management errors : a design issue for intelligent pilot-vehicle interfaces

    Creator:
    Chou, Chung-di
    Abstract:
    In conformity with advanced cockpit automation technology, modern pilots have become airborne system managers and have to satisfactorily manage complex sets of tasks to complete a flight mission safely. Funk's (1991) normative cockpit task management (CTM) theory defines CTM functions as the initiation, monitoring, prioritization, allocating of resources to, and...

  • Performance-based seismic design of light-frame shearwalls

    Creator:
    Kim, Jun Hee
    Abstract:
    Performance-based design has gained interest in recent years among structural designers and researchers. Performance-based design includes selection of appropriate building sites, structural systems and configurations, as well as analytical procedures used in the design process, to confirm that the structure has adequate strength, stiffness and energy dissipation capacity to respond...

  • 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,...
