Brazilian light wood frame system overview

Abstract Light wood frame (LWF) represents a great innovation for the civil construction sector in Brazil, due to its characteristics of material rationalization, operational flexibility, productive agility, competitive costs and also the efficient levels of cleaning and assembly time. For these reasons, this system is considered a promising constructive alternative. The objective of this study is to explore the potential of the system in Brazil. This research is an exploratory study, which uses as a collection tool a questionnaire of qualitative evaluation, applied with representatives of the civil construction involved with the LWF. The study proposes to analyze the critical variables that must be managed within the sector; investigates the needs and potentials of the constructive system; formulates competitive strategies for the diffusion of LWF in the country. The research results show that the expansion of LWF in Brazil is heavily dependent on government incentives; the increase in the integration of agents in both the civil construction value chain and the lumber sector; the need to disseminate more information to end users as a way to combat prejudice with the use of wood; and finally the need to train professionals to work directly with wood construction.摘要：轻型木结构（Light Wood Frame，LWF）凭借材料优化利用、作业灵活性、生产敏捷性、成本竞争力以及高效的清洁与装配时长控制等特性，成为巴西建筑工程领域的一项重大创新。基于上述优势，该体系被视为极具前景的建筑替代方案。本研究旨在探索该体系在巴西的应用潜力。本次研究为探索性研究，采用定性评价问卷作为数据收集工具，面向参与轻型木结构相关业务的巴西建筑领域代表开展调研。本研究拟分析该领域需管控的关键变量，探究该建筑体系的应用需求与发展潜力，并制定推动轻型木结构在巴西推广的竞争策略。研究结果表明，轻型木结构在巴西的推广高度依赖以下要素：政府的政策扶持；建筑工程价值链与木材行业各方主体间整合程度的提升；向终端用户普及更多相关信息，以消解其对木结构应用的认知偏见；以及培养直接从事木结构建造的专业人才。
