Using smartphone-captured images and an improved SIFT-WOOD feature extraction algorithm, it achieves robust 3D reconstruction of wood surfaces under challenging lighting and weak textures via SfM-MVS. The reconstructed model is post-processed and incorporated into finite element software, where orthotropic elastic, anisotropic elastoplastic, and viscoelastic constitutive models simulate mechanical response and long-term performance. A novel "stress-range volume method" quantifies the correlation between damage volume and load-bearing capacity, supported by a standards-based damage classification system. Guided by minimal intervention principles, controlled simulations identify damage repair priorities and inform a stepwise restoration strategy. This framework establishes a complete technical pathway—from geometric digitization to quantitative mechanical evaluation—characterized by low cost and high efficiency, significantly improving the scientific basis and practicality of conservation practice.

historical timber structures. Using smartphone-captured images and an improved SIFT-WOOD feature extraction algorithm, it achieves robust 3D reconstruction of wood surfaces under challenging lighting and weak textures via SfM-MVS. The reconstructed model is post-processed and incorporated into finite element software, where orthotropic elastic, anisotropic elastoplastic, and viscoelastic constitutive models simulate mechanical response and long-term performance. A novel \"stress-range volume method\" quantifies the correlation between damage volume and load-bearing capacity, supported by a standards-based damage classification system. Guided by minimal intervention principles, controlled simulations identify damage repair priorities and inform a stepwise restoration strategy. This framework establishes a complete technical pathway\u0026mdash;from geometric digitization to quantitative mechanical evaluation\u0026mdash;characterized by low cost and high efficiency, significantly improving the scientific basis and practicality of conservation practice.\u003c/p\u003e","manuscriptTitle":"An Integrated Approach for the Analysis of Historic Timber Structures Combining Enhanced Photogrammetry and Finite Element Modeling","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2025-12-04 13:58:08","doi":"10.21203/rs.3.rs-8222137/v1","editorialEvents":[{"type":"communityComments","content":0},{"type":"decision","content":"Revision requested","date":"2026-03-27T17:33:57+00:00","index":"","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2026-03-27T14:37:16+00:00","index":"hide","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2026-03-27T09:30:32+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"331835959737867411560068786383500019038","date":"2026-03-24T09:35:02+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"125973943837917919347785425345502360979","date":"2026-03-19T13:39:38+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"297513783202422734302445258091472710017","date":"2026-03-19T13:33:06+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"258673193419959912740433042532646726280","date":"2026-03-17T14:17:19+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"111109867884043731768796478813505658677","date":"2026-02-11T06:03:30+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"5028040002749190337416487799738760230","date":"2025-12-05T03:30:15+00:00","index":"hide","fulltext":""},{"type":"reviewersInvited","content":"","date":"2025-12-02T17:54:18+00:00","index":"","fulltext":""},{"type":"editorAssigned","content":"","date":"2025-12-02T14:52:36+00:00","index":"","fulltext":""},{"type":"checksComplete","content":"","date":"2025-12-02T14:51:47+00:00","index":"","fulltext":""},{"type":"submitted","content":"npj heritage science","date":"2025-11-27T12:30:29+00:00","index":"","fulltext":""}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"npj-heritage-science","isNatureJournal":false,"hasQc":true,"allowDirectSubmit":false,"externalIdentity":"hsci","sideBox":"Learn more about [Heritage Science](http://heritagesciencejournal.springeropen.com)","snPcode":"40494","submissionUrl":"https://submission.nature.com/new-submission/40494/3","title":"npj Heritage Science","twitterHandle":"@SpringerOpen","acdcEnabled":true,"dfaEnabled":true,"editorialSystem":"em","reportingPortfolio":"BMC/SO AJ","inReviewEnabled":true,"inReviewRevisionsEnabled":true}}],"origin":"","ownerIdentity":"78433f03-e88f-45c1-bd37-68e7f83b9e4c","owner":[],"postedDate":"December 4th, 2025","published":true,"recentEditorialEvents":[],"rejectedJournal":[],"revision":"","amendment":"","status":"under-review","subjectAreas":[],"tags":[],"updatedAt":"2026-05-19T16:08:15+00:00","versionOfRecord":[],"versionCreatedAt":"2025-12-04 13:58:08","video":"","vorDoi":"","vorDoiUrl":"","workflowStages":[]},"version":"v1","identity":"rs-8222137","journalConfig":"researchsquare"},"__N_SSP":true},"page":"/article/[identity]/[[...version]]","query":{"redirect":"/article/rs-8222137","identity":"rs-8222137","version":["v1"]},"buildId":"8U1c8b4HqxoKbykW_rLl7","isFallback":false,"isExperimentalCompile":false,"dynamicIds":[84888],"gssp":true,"scriptLoader":[]}
