Advancements in Wood-Based Construction: The Tallwood Project
Introduction
The journey of wood research has evolved significantly since its inception in 2004, leading to groundbreaking innovations in building safety and sustainability. A pivotal collaboration between leading experts in structural engineering and pioneering companies has resulted in two world records: the largest and tallest full-sized wood buildings tested to date. This article delves into the details of the Tallwood project, highlighting its design innovations, resilience against earthquakes, and the vital partnership with Simpson Strong-Tie.
The relationship between structural researchers and Simpson Strong-Tie began with large-scale shake table tests aimed at demonstrating the safety and integrity of wooden structures during seismic events. This collaboration has flourished over the years, culminating in the Tallwood project, which aims to prove the viability of wood as a resilient and robust construction material.
From initial tests in Japan in 2009, the commitment has remained strong with ongoing exchanges of ideas and design innovations between the research team and Simpson Strong-Tie experts, including Steve Prior and his team. Their joint efforts have focused on building projects that prioritize structural safety while optimizing materials used in construction.
The Tallwood project embodies the concept of designing a building capable of withstanding seismic forces without incurring damage. A critical aspect of this design process was the development of innovative lateral and gravity systems. It is essential that these systems work hand-in-hand; a resilient lateral system cannot prevent devastation if the gravity system fails. The connection points between various structural components, particularly those linking beams and columns, are crucial for overall stability.
In a cutting-edge approach, researchers created a new class of connections for beams and columns, ensuring they can flexibly adapt during earthquakes. Over a hundred such joints have been cyclically stressed to simulate real-world seismic conditions, highlighting their robustness thanks to Simpson Strong-Tie’s meticulous design and fabrication process.
The Tallwood project's preliminary findings investigate the implementation of a groundbreaking rocking wall system traditionally associated with concrete structure. This innovative approach eliminates the need for standard anchoring techniques by allowing the wall to lift and realign itself during seismic activities. Steel post-tensioning rods, which function similarly to rubber bands, keep the walls grounded by pulling them back down after movement, significantly enhancing their damage resistance compared to conventional designs.
The uniqueness of the Tallwood project lies in its 10-story solid wood structure, a notable achievement since buildings of this height are typically made from a combination of materials. The successful implementation of a mass timber system challenges past conventions and opens doors for future constructions that harness similar strategies.
Goals for Sustainable Construction
Looking ahead, the Tallwood project's ambitions extend beyond mere testing of ideas; there is a vision to integrate these advancements into building codes. By standardizing these innovations, engineering professionals can be empowered to create buildings that not only meet safety demands but also contribute positively to the community and environment.
Selecting mass timber for such projects is pivotal as it represents a sustainable material that can be grown and harvested, further emphasizing eco-friendly construction practices. Simpson Strong-Tie serves not only as a source of critical materials but also as a collaborator in the realms of innovation and development, moving construction techniques to new heights.
The partnership between structural engineering experts and Simpson Strong-Tie in the Tallwood project marks a monumental step forward in seismic-resistant wood-based construction. As the industry transitions toward incorporating these findings into established practices and buildings, the potential for mass timber to revolutionize and enhance the built environment is increasingly tangible. Ultimately, this project not only aims for structural integrity but also fosters a sustainable future in construction.
