• Abstract:
  Camber in precast and prestressed concrete is currently designed using best practices in structural engineering and subject to climate and loading uncertainties. Applying new technology of adaptive structures, large shape changes in response to load, to precast concrete bridge girders would pioneer a new innovative field of research and design. This work building, analyzing, and validating an adaptive precast girder system that will use expanding anchors to camber the compression face of the girder to counteract imposed loads. By providing on-demand camber, sizing of the precast member for deflection criteria can be reduced. Through this form of topology optimization, reduction in concrete volume will increase the sustainability of the structural system. Laboratory experiments have led to fundamental science and implementable technology. Adaptive precast girders can address long-term effects of creep and changing design loads over the lifetime of highway bridges.
  
  The total size of the zip file is 27 MB. The file extension .md is among others related to texts and source codes in Markdown markup language. Markdown is a lightweight markup language, to write using an easy-to-read, easy-to-write plain text format, then convert it to structurally valid XHTML (or HTML) (for more information on .md files and software, please visit https://www.file-extensions.org/md-file-extension). File extension .json is associated to JavaScript Object Notation file format, a lightweight, text-based, language-independent data interchange format. JSON defines a small set of formatting rules for the portable representation of structured data. It is used by various applications as alternative option to XML file format. The data in a json file are stored in simple text file format and the content is viewable in any simple text editor (for more information on .json files and software, please visit https://www.file-extensions.org/json-file-extension). The .jpg file extension is associated with JPEG (Joint Photographic Experts Group) file format. JPEG is a lossy image compression algorithm that significantly reduces the file size of the original image at the cost of quality. The higher the compression ratio the lower the quality of the .jpg file (for more information on .jpg files and software, please visit https://www.file-extensions.org/jpg-file-extension). The .xlsx and .xls file types are Microsoft Excel files, which can be opened with Excel, and other free available spreadsheet software, such as OpenRefine.
