Building on timber’s natural capacity to efficiently transfer loads, this project of Life Sciences Research Center extends the investigation through mass timber systems - by leveraging engineered wood, CLT and Glulam, it enhances structural performance. The building form is driven by structural logic, expressed through the joints and connections of 2 primary systems: horizontal load-bearing members—glulam girders, beams,spandrels, and CLT floor plates—and vertical load-bearing elements— Glulam X-shaped columns.
45 × 110 cm girders transfer loads to a series of 30 cm-wide beams, forming Interlocked Floor System. At the perimeter, spandrel beams tie the system together, contributing to overall stability and seismic performance. Loads are then transferred to Glulam X-shaped columns, that form Interlocked Core System, spanning up to 9 meters, accommodating a range of programmatic configurations within the building.
