Wood specimens with dimensions (100\u00d7100\u00d710 mm and 300\u00d7100\u00d710 mm) matching fire performance tests were prepared, and artificial accelerated photoaging treatment was conducted to obtain aged samples with 0, 60 and 120 aging cycles in accordance with the accelerated aging test protocol for wood materials. The results indicate that pine combustion involves three distinct thermal stages: pyrolysis, smouldering, and flaming, with critical high-risk transition points identified. Aging intensified fire risk and related hazards across all stages, particularly accelerating flame spread on vertical components.<\/p>\n","protected":false},"author":6,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[5422],"tags":[5484,5485,1062,5483,5486],"release_year":[],"ppma_author":[5440,5441,5442,5443,5444,5445,5446],"class_list":["post-5882","post","type-post","status-publish","format-standard","hentry","category-wood-research-volume-71-number-1-2026","tag-ancient-timber-structure","tag-combustion-characteristic","tag-fire-risk","tag-smoke-and-heat-hazards","tag-wood-aging"],"featured_image_src":null,"author_info":{"display_name":"Katar\u00edna Kalu\u017en\u00e1","author_link":"https:\/\/www.woodresearch.sk\/cms\/author\/kaluznavupc-sk\/"},"authors":[{"term_id":5440,"user_id":0,"is_guest":1,"slug":"tianwei-zhang","display_name":"TIANWEI ZHANG","avatar_url":"https:\/\/secure.gravatar.com\/avatar\/?s=96&d=mm&r=g","0":null,"1":"","2":"","3":"","4":"","5":"","6":"","7":"","8":""},{"term_id":5441,"user_id":0,"is_guest":1,"slug":"mingze-bai","display_name":"MINGZE BAI","avatar_url":"https:\/\/secure.gravatar.com\/avatar\/?s=96&d=mm&r=g","0":null,"1":"","2":"","3":"","4":"","5":"","6":"","7":"","8":""},{"term_id":5442,"user_id":0,"is_guest":1,"slug":"hao-liu","display_name":"HAO LIU","avatar_url":"https:\/\/secure.gravatar.com\/avatar\/?s=96&d=mm&r=g","0":null,"1":"","2":"","3":"","4":"","5":"","6":"","7":"","8":""},{"term_id":5443,"user_id":0,"is_guest":1,"slug":"zidong-guo","display_name":"ZIDONG GUO","avatar_url":"https:\/\/secure.gravatar.com\/avatar\/?s=96&d=mm&r=g","0":null,"1":"","2":"","3":"","4":"","5":"","6":"","7":"","8":""},{"term_id":5444,"user_id":0,"is_guest":1,"slug":"zhixin-tang","display_name":"ZHIXIN TANG","avatar_url":"https:\/\/secure.gravatar.com\/avatar\/?s=96&d=mm&r=g","0":null,"1":"","2":"","3":"","4":"","5":"","6":"","7":"","8":""},{"term_id":5445,"user_id":0,"is_guest":1,"slug":"hao-chang","display_name":"HAO CHANG","avatar_url":"https:\/\/secure.gravatar.com\/avatar\/?s=96&d=mm&r=g","0":null,"1":"","2":"","3":"","4":"","5":"","6":"","7":"","8":""},{"term_id":5446,"user_id":0,"is_guest":1,"slug":"xiaorui-zhang","display_name":"XIAORUI ZHANG","avatar_url":"https:\/\/secure.gravatar.com\/avatar\/?s=96&d=mm&r=g","0":null,"1":"","2":"","3":"","4":"","5":"","6":"","7":"","8":""}],"_links":{"self":[{"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/posts\/5882","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/users\/6"}],"replies":[{"embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/comments?post=5882"}],"version-history":[{"count":1,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/posts\/5882\/revisions"}],"predecessor-version":[{"id":5884,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/posts\/5882\/revisions\/5884"}],"wp:attachment":[{"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/media?parent=5882"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/categories?post=5882"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/tags?post=5882"},{"taxonomy":"release_year","embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/release_year?post=5882"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/ppma_author?post=5882"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
