Session 3: Structural use of bamboo culms (Part 2)
Speaker: Zhuo Xin, Associate Professor of College of Civil Engineering and Architecture at Zhejiang University
Topic: Innovative multi-culm bamboo spatial lattice structures
The innovative multi-culm bamboo spatial lattice structures are composed of bamboo culm triangle installation units which are connected in the way that all simple connectors are the same. The topological relationship of this structural system differs from that of the traditional spatial lattice structures. A free-form surface lattice structures can be assembled in the way of tangent direction parallel connection between adjoining installation units. The bearing capacity of the structures can be strengthened in the way of normal direction parallel connection between adjoining installation units. The feasibility of this structural system has been validated by engineering applications.
Speaker: Luis Felipe Lopez, Head of Technology at Base Bahay Foundation in the Philippines
Topic: Research in the Philippines
Base Bahay Foundation is a non-profit organisation dedicated to providing disaster-resilient, sustainable socialised housing for low-income families and disaster victims using the Cement-Bamboo Frame Technology (CBFT). However, though the CBFT has been tried and tested in our various projects around the country, Base remains dedicated to constant research and innovation for the optimization of the technology.
This can be achieved through the Base Innovation Center where Base conducts research on bamboo construction technology, in collaboration with various international and local universities. Together with our partner institutions, the BIC aims to further bamboo technology and promote this for widespread use.
Speaker: David Trujillo, Chair of INBAR Construction Task Force, Assistant Professor at Coventry University
Topic: Making bamboo a mainstream structural material
Bamboo has been used as a construction material for thousands of years and currently hundreds of millions of people live in bamboo housing across the world, yet it is still perceived as non-conventional material. This is because most of bamboo constructions are vernacular. Over the last 20 years a significant effort has been made to transform it into another engineering material. This presentation identifies the state-of-the-art of bamboo engineering, including the significant progress made in the development of standards (and codes) and also identifies the path yet to cover.

Mathematical mysteries have challenged humanity’s most powerful thinkers and inspired passionate, lifelong obsessions in search of answers. From the strangeness of prime numbers and the nature of infinity, to the turbulent flow of fluids and the geometry of hyperspace, mathematics is our most potent tool for revealing immutable truths. The event was a vibrant tour to the boundaries of the mathematical universe, and explore the deep puzzles that have been solved, the masterminds who powered the breakthroughs, and the towering challenges that have shaken the confidence of some of today’s most accomplished mathematicians—even as they enlist new ways to pursue mathematical truths.

For all we understand about the universe, 96% of what’s out there still has scientists in the dark. Astronomical observations have established that familiar matter—atoms—accounts for only 4% of the weight of the cosmos. The rest—dark matter and dark energy—is invisible to our telescopes. But what really is this dark stuff? How do we know it’s there? And what does it do? From the formation of galaxies to the farthest reaches of space, it appears that darkness rules. Without dark matter and dark energy, the universe today and in the far future would be a completely different place. We were joined by leading researchers who smash together particles, dive into underground mines, and explore the edges of the known universe in search of clues to nature’s dark side.
