Древесина перекрестноклееная (ДПК/CLT) начинает завоевывать рынок в России.

На основании анализа результатов экспериментальных исследований стойкости ДПК/CLT к атмосферным воздействиям составлен ряд рекомендаций, которые предлагается включить в СП 64.13330.2017 для соблюдения при проектировании, изготовлении и строительстве зданий с применением конструкций из ДПК/CLT.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Cross-laminated timber (CLT) has started to win a market in Russia. Humidity plays an important role in ensuring the operational reliability of buildings based on timber structures. The lack of comprehensive studies on the influence of varying temperature and humidity actions, including atmospheric ones, hinders the development of CLT.</p></sec><sec><title>Aim</title><p>Aim. In this work, the influence of atmospheric actions on various types of CLT building structures was determined in order to amend the requirements in SP 64.13330.2017 for the design and protection of CLT structures.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Samples of CLT wall panels and floor slabs manufactured as per the current regulatory documents were used as an object of research. Field tests were developed in order to determine the influence of atmospheric actions on the strength and elastic characteristics of CLT panels.</p></sec><sec><title>Results</title><p>Results. Atmospheric actions have an adverse effect on the strength and elastic characteristics of CLT panels. The decrease in the strength and elastic characteristics varies for the samples of floor slabs and wall panels.</p></sec><sec><title>Conclusion</title><p>Conclusion. It is proposed that several recommendations given based on the experimental results on the resistance CLT to atmospheric actions are to be included in SP 64.13330.2017 for the design, manufacture, and construction of buildings using CLT structures.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>деревянные конструкции</kwd><kwd>слой древесины</kwd><kwd>древесина перекрестноклееная (ДПК/CLT)</kwd><kwd>переменные температурно-влажностные воздействия</kwd><kwd>прочностные и упругие характеристики</kwd><kwd>защитные лакокрасочные покрытия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>timber structures</kwd><kwd>wooden layer</kwd><kwd>cross-laminated timber (CLT)</kwd><kwd>variable temperature and humidity actions</kwd><kwd>strength and elastic characteristics</kwd><kwd>protective paint coatings</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Nakajima S., Sakabe Y., Kimoto S., Ohashi Y.
