About

This project was developed by Mark Denavit and Peter Talley at the University of Tennessee, Knoxville. Funding for this project was provided by the American Institute of Steel Construction (AISC) through the Teaching Aid Development Program.

aisc-model-viewer's Issues

Implement sidebar

Implement sliding sidebar with links to the associated drawings, calculations, etc. Possibly use the viewer object to keep track of things? Or create a new Page class that manages the viewer, sidebar, header, etc.

Allow linking to specific model

We should be able to share a link to a specific model. At the moment I think we'll implement this via query strings.

Add figures and links to double angle connection calculations

A number of figures need to be added to the double angle connection calculations. Also need to link tension rupture and block shear rupture models to relevant parts of the calculations. Comments in the html file indicate what is needed.

Improve rendering of model

Currently the rendered model uses flat shading that makes it hard to distinguish edges. This could be an issue of simply picking a different shader, or may need something more complicated.

Check and update gusset plate thickness for double angle connection

The thickness of the gusset plate might be 1/2", not 5/8" as currently in the calculations. Need to confirm the physical thickness and if not 5/8" then update the calculations.

WT Connection

Models:

• Primary 3D model
• Tensile rupture
• Block shear 1: web shear
• Block shear 2: flange shear + flange tension
• Block shear 3: flange shear + web tension

2D Drawings:

• Primary 2D drawing
• Distance l for shear lag

Calculations:

• Tensile yield
• Tensile rupture
• Block shear 1
• Block shear 2
• Block shear 3

More fun:

• "What if" questions

Implement clearScene

ModelViewer.clearScene() doesn't actually do anything at the moment.

Add UTK and AISC logos to front page

UTK: "Centered" variant

Collections: incorrect href for Link

Links are generating incorrect hrefs at the moment; for example the double angle calcs are being linked to double-angle/calculations.html instead of just calculations.html.

Requested changes from May 29 check-in

• Make the sidebar default to off for mobile
• In the tensile rupture model, pull the double angle a bit farther away from the connection
• Add strength equation to model page (e.g. add Pn = (AnU)Fu to the tensile rupture model, with An highlighted the same color as the area)
• On the more fun page, add
  • a figure showing the work point
  • a request for other more fun items
  • some "what if" questions
  • something about U
• WF on its side as the home icon

Lots of ways to show bolts

Abbreviations

• Near side/far side

Drawing conventions

• Don't double define dimensions

Contribution documentation

Guide to contributing needs to be written.

Revise main page text

Main page needs a second pass.

Model does not appear until interacted with

Desired behavior: model appears when page loads.

Container for renderer doesn't ever shrink

The container for the renderer doesn't ever shrink. It seems to grow properly, but resizing the window smaller gradually moves the model off-screen. Inspecting the element shows that its height only ever increases. My current suspicion is that this is a CSS issue, possibly with flexbox.

Model paths relative to root, not bundle

Paths to the model files are currently being interpreted relative to the root instead of the location of the main bundle. So the viewer works fine locally when using the webpack dev server, but when uploading it to Volweb the model page looks for https://volweb.utk.edu/neyland-connection.gltf instead of https://volweb.utk.edu/~ptalley2/model-viewer/neyland-connection.gltf. (Main bundle is at ~ptalley2/model-viewer.)

This may be caused by f12b867, which changed how file-loader handled assets.

Each page should have credits, whether on the page itself or on a master page. e.g.

Maybe it doesn't have to broken down by pieces, and could just be (in alphabetical order?)
