PROJECT DESCRIPTION

Three long-span timber gridshells which function as greenhouses, ranging from 11m to 29m in height and 43m to 88m in diameter. The buckling performance of these slender shells was critical. Significant full-scale structural testing was conducted to prove the stiffness and capacity of unique hidden connections.

Judge's comment:

The Taiyuan Botanical Garden complex features three paraboloid domes ranging from 43m to 88m in diameter and from 12m to 30m in height. The largest of the three domes is thought to be the longest clear-span timber gridshell (non-triangulated) in the world which achieved the goal of a low  carbon footprint.
 
The complex geometry inherent in this architectural form made parametric design and structural optimisation of paramount importance. The careful planning of the design, fabrication, transportation, and construction sequence resulted in a problem free erection on site with very little site alteration required.

The project pushes the boundaries of structural engineering, materiality, and construction technique. The use of a unique optimised geodesic grid allowed minimisation of doubly curved glulam, and enabled manufacturing times to handle an intense construction schedule.
