A reading room for
timber engineering.
LingoScholar brings the literature into one place, so a research question can become a reading path. Explore materials and structural topics, connect references, and keep your own research thinking close to its sources.
Explore the catalogueFind your way into the literature.
Anyone can browse the catalogue, without signing in. Coverage includes CLT, glulam, LVL, solid timber and other engineered timber.
- Combine materials, structural topics and research methods. Search titles, authors, DOI and available abstracts.
- Open paper details, visit publisher pages, and follow available references through the citation explorer.
- Share a filtered search or a public paper page. Export references as BibTeX, RIS, CSV or formatted text.
- Explore the research radar and public reading lists published by the owner.
Keep your evidence connected.
The private workspace belongs to the catalogue’s owner. Uploaded PDFs, notes, evidence and screening decisions stay in this protected area.
- Read your uploaded PDFs, select text, highlight passages and save page-linked notes.
- Organize study cases in an evidence matrix, retain original units and mark full-text checks when completed.
- Build project collections, compare research records and screen papers in two systematic-review stages.
- Keep research records across devices and download a full ZIP backup, including your PDFs.
Make the catalogue work for you.
How do I begin a focused search?
Try a material and a structural topic first—for example, CLT and Shear walls, or GLT / Glulam and Beams. Add a method or a phrase to narrow the results. Use More filters for publication year and access. Each active filter can be removed individually. Share search copies a link that keeps your choices.
What does the research radar score mean?
Topic fit reflects keyword matches in titles and available abstracts, using explicit focus weights. The match reasons are shown beside each paper. A score describes relevance to a research interest; it does not establish study quality, validate findings or replace reading the full text.
How does the benchmark exchange work?
The cross-lab benchmark exchange provides shared, versioned experimental cases. Approved academic researchers can submit predicted curves, software versions and model assumptions. The server calculates comparison metrics. Submissions remain private until owner review and a separate publication decision. Published reports credit contributors and keep case versions and declared calibration histories distinct.
The initial cases use published solid CLT wall measurements from one campaign. They are open benchmarks. A full fixed displacement range is required for curve RMSE; incompatible or unavailable metrics are withheld. See the comparison methods. LignoScope records can be transferred through the supported explicit evidence and project workflows; an exchange comparison does not automatically validate a model.
What is LignoScope Research Studio?
LignoScope Research Studio is a separate timber research program developed by Mohammadreza Khajehpour. A limited public demo is available without an account. The full browser workspace requires a LingoScholar account and separate owner approval. Its tools include CLT wall and beam studies, finite-strain 3D research mechanics, laboratory geometry, layer visualization, support and mesh checks, and portable Save/Open projects. Software verification checks are documented; independent experimental validation remains ongoing, with the W08 model/measurement disagreement and W12 source-geometry conflict explicitly retained.
What is the Reproducibility Lab?
The Reproducibility Lab provides editable effective-property wall and beam models, campaign-based model comparisons, proposed-test ranking and source-linked research packages. Approved academic accounts can use the workspace and submit research records for review. Demonstration inputs are labelled synthetic; a data package does not imply a verified reference model. Read the published methods and assumptions before interpreting results.
What can I do in the specimen atlas?
Find experimental specimens by geometry, lay-up, openings and test protocol. Match reasons distinguish recorded differences from missing information. Follow campaign links across related reports and inspect source-linked failure sequences when available. Academic members can compare two test setups and use model curve benchmarks. The starter collection contains seven source-checked solid CLT wall tests from one campaign; verified openings and VOL cases will be added as they are curated.
Register for academic access to compare test compatibility and overlay your model CSV on a measured curve. Your model file and downloaded report stay in your browser; they are not sent to the website. Units and displacement definitions must agree. Curve metrics state their methods and limitations, and cyclic histories are not silently converted into monotonic envelopes. These comparisons do not certify a model or replace engineering judgement.
Public atlas records are curated separately from the owner’s private PDFs and notes. Source-checked means the recorded fields were checked against their cited sources; an unknown field remains unknown. Display curves are reduced from measured data with their peaks preserved, and full-resolution CSV extracts and reuse licences are linked.
Which tools require academic access?
The literature catalogue, research radar, author pages and public specimen records remain open. Advanced compatibility comparisons, model curve benchmarks and comparison report exports require academic registration. Create a LingoScholar account with your institutional email and a password. Access requires owner review and activation through a private link delivered to that academic mailbox. Registration stays pending until approval and email activation are complete. Institutional email is an access condition, not a guarantee of researcher status.
Your registration details are private. Academic membership never grants access to the owner’s PDFs, notes or management workspace. Model CSVs remain in your browser. See the academic access privacy notice.
How does the author directory group papers?
Browse authors alphabetically using their displayed publisher names, or search a name to see the papers indexed in LingoScholar. The directory uses public Crossref metadata and updates when the catalogue changes. Matching names can belong to different people, and spelling variants can create separate groups. These are publication name groups, not verified identity profiles or complete career bibliographies. Private uploads and owner notes never appear in the directory.
Where do the references and citation links come from?
The catalogue uses Crossref publisher metadata. Citation lookups use OpenAlex when available, with publisher-deposited DOI references from Crossref as a fallback. Coverage varies between providers. Related topic matches are labelled separately from citation relationships. A publisher PDF link or license indicator does not guarantee unrestricted access.
How often is the literature updated?
The linked weekly update runs on Fridays at 8:00 a.m. in the America/Toronto timezone. “Newly discovered” means added to the catalogue in the last seven days; these papers may have been published earlier. “Recently published” uses complete publication dates supplied by publishers. Historical coverage grows over time and is not exhaustive.
Can I use LingoScholar on my iPad or phone?
Open lingoscholar.com in Safari, then choose Share → Add to Home Screen. Enable Open as Web App if Safari offers that option. Use Install app in the header for instructions for your device. The Home Screen icon opens LingoScholar as a standalone web app. A network connection is required.
Are there faster ways to navigate?
Use Quick search in the header, or press ⌘ K on Mac and Ctrl K on Windows. Search the catalogue or jump to a material, structural topic or research tool. Choose the comfortable layout for abstract previews, or the compact layout to scan titles. Select two to six papers for a comparison.
What becomes public when a reading list is published?
The owner can publish a project collection as a reading list. Its name, description and Crossref references become public. Uploaded-only references, PDFs, notes, evidence and review decisions remain private. Unpublishing removes public access to the reading list.
How does visitor analytics protect my privacy?
LingoScholar records successful public page loads, approximate country, broad device type and referring domain to understand readership. For Canadian page views, an approximate city and province or territory may be supplied by hosting or estimated on this site using a local IP-location database; these are retained only as daily aggregate page-view counts. Visitor network addresses are not sent to an external geolocation service. Your network address is processed to estimate a Canadian city when applicable and to make a keyed daily visitor code; the raw address and full browser string are not saved. This code changes each day and cannot identify you by name. There are no analytics cookies, street addresses, GPS coordinates, full referring URLs or saved search parameters.
Only the owner can view the reports. Private pages, owner sessions and known bots are excluded. Analytics records are kept for 90 days, independently of research files. Requests with Do Not Track or Global Privacy Control enabled are not counted. Country, Canadian city and visitor estimates may be affected by VPNs, mobile or shared networks and automated traffic. A reported city describes an approximate network location, not a verified location of a person.
Local Canadian city estimates use IP Geolocation by DB-IP (City Lite, CC BY 4.0), adapted to retain only Canadian IP ranges and city/province labels without coordinates.

Khajehpour
Civil engineering researcher · Timber structures
I completed my PhD in Civil Engineering at the University of Ottawa in October 2025. My research focuses on monolithic cross-laminated timber shearwalls with openings, and on lintel and parapet beams with vertical outer laminations (VOL).
I combine experimental testing, nonlinear structural modelling and mechanics-based design methods to understand how timber structures behave. My doctoral experimental programme included 42 beam tests and 12 full-scale shearwall tests. I also develop timber analysis and design tools, including LignoNL and VOLAR, and taught Structural Design in Timber at the University of Ottawa in Fall 2024.

Why I built LingoScholar
Finding a relevant paper is only the beginning. I built LingoScholar to make timber literature easier to explore and to connect experimental specimens, test conditions and modelling comparisons to their original sources. My aim is to help researchers build on evidence they can trace and check.
