Cross-laminated timber (CLT) has gained popularity worldwide as a sustainable building product, attracting the attention of designers, engineers, and builders in recent years. However, behaviour under fire is significant concern because its combustible nature. Only limited research been conducted on CLT using finite element (FE) analysis. The main aim this study to develop an FE model investigate wall panels exposure standard conditions. accuracy was validated by comparing experimental results temperature distribution at different thickness depths obtained from literature, with predicted numerical Furthermore, comparative analysis performed establish resistance, charring rate, charred depth panels, outcome compared results. temperatures within were observed be good agreement exposure, which may reduce number necessary lab experiments future.

To date, the existing literature lacks any studies that compare timber and concrete apartment buildings in Finnish context regarding their carbon footprint, handprint, cost of frame structures. This study rigorously analyzes calculates costs associated with various structural solutions a proposed multi-story building located Laajasalo, Helsinki, Finland. While primary focus is on wooden construction, exploring both its challenges opportunities, this also includes comparative assessment construction. In Finland, regulations require sprinkler fire extinguishing system to be installed inside. Also, weather protection typically added top connection construction buildings. When are taken into account, achieving positive climate effects through 290% higher than solid wood frame. Our findings will provide robust basis for assessing sustainability feasibility methods, offering valuable insights environmental economic considerations decision-makers Finland beyond as evolve awareness impacts grows.

Many countries, including Poland, are currently testing the construction of multi-family houses using a prefabricated system glued laminated timber (CLT). Poland has great potential for application wood technologies in housing sector. The purpose article is to analyse real advantages this technology, as well difficulties and threats. It important determine boundary conditions location type construction, such legal force each country, especially with regard fire protection buildings, availability local resources, transport distance between place extraction raw material, production CLT panels, prefabrication elements final site. A separate problem be considered overcoming mental barrier society that accustomed durability house concrete or brick structure, associates impermanence. Other bottlenecks development high price imported low level social acceptance wooden structures long-term, stable safe solution.

Given that CLT is a relatively recent innovation, there notable scarcity of market research in Finland. Presently, limited body literature provides thorough comprehension the present state, varied applications, and anticipated future developments concerning use within Finnish construction sector. The availability data underscores need for more extensive studies to fill this knowledge gap provide nuanced insight into evolving landscape adoption industry. This article aims through semi-structured, in-depth interviews with 15 experts. Key findings highlighted (1) hierarchical order familiarity among professionals Finland, ranging from highest lowest, was identified as follows: architects, engineers, developers, builders, contractors; (2) pronounced necessity exists heightened expertise training realm CLT; (3) considered promising option endeavors aimed at mitigating impacts climate crises; (4) showcased adaptability environments marked by highly fluctuating climatic conditions, emphasizing importance comprehensive approach, including proactive maintenance strategies; (5) Finland adopted commendable forward-looking sustainable practices forest management; (6) across wide range building categories; (7) perceived vulnerabilities primarily included lack cost-competitiveness, insufficient sound insulation, inadequate production volume; (8) key prospects encompassed versatility CLT, increasing demand propelled environmental considerations, collaborative advancements hybrid techniques. will contribute greater usage industry revealing challenges, potential, outlook use.

Purpose Cross-laminated timber (CLT) is an innovative construction material that provides a balanced mix of structural stiffness, fabrication flexibility and sustainability. CLT development innovation diffusion require close collaborations between its supply chain architectural, engineering, manufacturing (AECM) stakeholders. As such, the purpose this study to provide preliminary understanding knowledge process construction. Design/methodology/approach The implemented longitudinal social network analysis AECM companies involved in 100 projects UK. project data were acquired from industry publication decoded form multimode project-company network, which was projected into single-mode company collaborative network. This complete filtered four-phase allow over time. A set node metrics used characterize topology patters centrality companies. Findings highlighted scale-free structure depends on influential hubs manufacturers, engineers contractors accelerate diffusion. However, such more vulnerable disruptions due dependence these few prominent hubs. Also, network’s decreased modularity confirms maturity technology formation cohesive clusters partners. macro approach critical role upstream stakeholders their higher centralities Stronger found (timber manufacturers) downstream (architects main contractors). Originality/value contributes field industrialized by characterizing networks are propose governmental policies initiatives advance sustainable material.
