NEWS CHINESE UNIVERSITY COMPLETES MODULAR CLT STRUCTURE SHAKING TABLE TEST According to Canada Wood China, Tongji University’s College of Civil Engineering, led by Prof Xiong Haibei, recently achieved a milestone with the completion of the shaking table test for a modular cross-laminated timber (CLT) structure. The shaking table test assesses the seismic performance of structures. Prof Xiong’s team introduced a structure system known as FaM (Fire and Movement), which is a hybrid building system that combines modular wood boxes with a concrete frame-and-core structure. This system allows for the incorporation of modular units, which can be constructed off-site using light wood frame, mass timber, or glue-laminated timber (glulam) post and beam structures, and placed on the concrete slab. The main concrete structure serves as the primary load-bearing element, supporting the overall structural weight. It possesses high stiffness in the vertical direction to carry the load and exhibits seismic resistance in the horizontal direction. The substructure provides load-bearing capacity and seismic resistance for the modular units themselves. A unique feature of the FaM system is the incorporation of a concrete floor slab with a concrete core on every third floor. This design ensures compliance with fire protection requirements and enables safe evacuation in high-rise wooden structures, as claimed by Canada Wood China. By implementing this approach, the FaM system not only enhances fire safety but also reduces the cost of fire protection in wooden constructions. The FaM system aims to provide a promising solution for achieving efficient, sustainable, and adaptable construction practices in various architectural projects. The team behind developing FaM (Image: Canada Wood China) Canada Wood China reported that the modular CLT structure performed “exceptionally” under the shaking table tests, especially when combined with new energy dissipating connectors. The modular CLT structures used in the test were constructed using Canadian lumber. Under varying seismic loads with different spectral characteristics, the system exceeded the team’s preset goals. The successful test showcased the structural integrity and stability of the modular CLT design, highlighting its potential for widespread adoption in seismic-prone regions. WIA METSÄ GROUP TO EXPAND KERTO LVL PRODUCTION WITH NEW MILL IN ÄÄNEKOSKI, FINLAND Metsä Group has announced plans to build a new Kerto laminated veneer lumber (LVL) mill in Äänekoski, Finland, for the production of beam and panel products used in the construction industry. The value of the investment is €300m, and the mill is expected to begin production in late 2026. The mill’s annual production capacity is approximately 160,000m 3 , which represents a 50% increase in the company’s total Kerto LVL capacity. Kerto LVL production primarily serves the construction industry in the European market. The new mill will use around 400,000m 3 of log procured from Finland. It will be on the Äänekoski integrated mill site, which harnesses synergies such as energy production, logistics and mill services. The integrated mills can reportedly utilise 100% of the side streams produced in the production of Kerto LVL, producing the maximum possible added value from the valuable raw material. Furthermore, the new mill will have a direct employment impact of around 150 new jobs. It will also add some 200 person-years to its direct value chain. The employment impact of the construction phase is estimated to be approximately 1,000 person-years. Kerto LVL is a construction material which combines material efficiency with the high added value of wood. Its technical performance makes it suitable for versatile construction uses such as elements and modular construction. “Most of the carbon footprint of construction comes from the building materials. The construction industry is now seeking more sustainable alternatives, so we are seeing growing interest in construction material based on renewable raw materials,” said Jaakko Anttila, executive vice-president, Metsä Wood. “Thanks to its material efficiency, Kerto LVL is a competitive and sustainable solution for the increasing use of wood in construction.” Metsä Group currently produces Kerto LVL products in Lohja and Punkaharju in Finland.

NEWS RAUTE RECEIVES €44.6M ORDER TO FRANCE Raute Corporation has signed a contract worth €44.6m with the Thebault Group in France for the technology delivery of a new greenfield laminated veneer lumber (LVL) production plant. The plant, which will reportedly be the “first LVL plant in France”, according to Raute, will eventually produce 100,000m 3 of LVL, with this agreed delivery covering a first phase at 70,000m 3 . The order for Raute’s technology includes all the production processes from veneer peeling to LVL billet handling, including extensive service package. The lines are a complete solution compiled of the latest most automated R7-Series technologies. The ordered machinery and equipment will be delivered during 2024. They will be manufactured at Raute’s production units in Lahti and Kajaani in Finland, and in the company’s partnership network. This new plant, which will be in full operation in 2026, is part of Thebault’s development to extend its offering particularly to the construction industry. Driven by a fast-growing market, this French production of engineered wood products will expand the offer of bio-sourced materials contributing to the decarbonisation of the building sector. “Thebault is our long-term customer, and we are very pleased to continue our close partnership with them on this new project,” said Mika Saariaho, president and CEO of Raute. “Raute is committed to provide its latest innovations and complete end-to-end expertise How the new production plant might look like (Image: Raute) to build a new world-class LVL plant for Thebault.” The family-owned Thebault Group produces 125,000m 3 of plywood annually in France, making almost 50% of the total domestic plywood production.
