Innovative Connections For Cross Laminated Timber (CLT) Structures (Webinar)

Connections are the critical component when designing and building with timber structures.
Recent innovations have enabled us to engineer our buildings to increase in scale, while improving safety and productivity of installation and optimising the amount of wood on site.
In this webinar, Matteo Andreottola from Rothoblaas will discuss:
- The modern angle brackets and how they transfer shear and tension forces
- Recent innovative connections including the Alustart, Spider and Pillar connections
- Design criteria that enable post and plate construction
Speaker:
Matteo Andreottola, Technical Consultant @Rothoblaas
Matteo graduated with full marks at the university of Trento, with a thesis on a design of an exhibition centre with timber structures (with the well-known professor Maurizio Piazza). The design of timber structures has always been his passion and job after the end of the university. He worked in Ireland as a structural engineer for IJM timber frame engineering, one of the main timber frame companies in the country. He came back to Italy after this working experience abroad, to work as a structural engineer for Xlam Dolomiti, a company which designs and produces timber structures with CLT. With the company he participated in the structural design of big projects in Australia, like Grocon, Northumberland Street and Ballarat GovHub. Currently, he is working as a technical consultant for Rothoblaas, following projects all around the world, especially in Australia, USA, South America and Spain.

Greeting from Perú, great video

[@smannick]

Fantastic video for me as a structural engineer looking to start designing Clt.

[@Ayogenius67]

Wat a materials, I need to start up this CLT industry

[@KyTaPb]

Thanks. Nice webinar. Curious, does anyone count impact of aluminium connections on embodied carbon of the CLT buildings?

[@henryirazabal2118]

Thanks. Can you post a video step by step calculations of CLT floor thickness and glulam post dimensions not glulam beams ? Please

[@user-ls1gg7lj1l]

Hi, is this construction process suitable for Australia as well?

[@2brazy4ubitch]

imagine someone proposing aluminum connections for aluminum or steel or concrete structures..... everyone would be like, uh, no, metal fatigue is too risky

[@schoolkeepa]

Isn't CLT construction more expensive than regular wood construction?

[@tokiomitohsaka7770]

That depends on your location and availability of supply. One of the big advantages of mass timber is that the material is much lighter than concrete and steel, so your foundations can be designed for a lower load, which makes it cheaper. The workforce needed for the construction is also smaller, and you need less trucks to bring the materials to the construction site. The lighter materials also mean you can use smaller cranes. The material itself is more expensive, especially in places like the US, but the other offsets can make the project still cheaper depending on many factors.

Not really. What matters is the labor. Paying carpenters to build up a full house frame will cost a LOT, plus you need to buy and get several products delivered, which also have a big CO2 footprint.
Getting walls prefabricated, mostly by CNT cuts, then delivered and basically instantly assembled together is far more economical and have a far lower CO2 footprint.
