Introduction
Tubular structures are synonymous with modern architecture, primarily in line with nature, like bamboos. The familiar range of tubular shapes sections includes square, rectangular, circular, elliptical and polygonal tubular sections. Tubular structures can be found in many structural applications including buildings, bridges, wind turbines, off-shore platform. Due to the closed-form nature, concrete infill become a natural consequence to enhance strength and stiffness and a concrete-filled member which has an excellent load-bearing, ductility and energy dissipation capacity. Due to the above-mentioned inherent advantages, tubular structural members are also being adopted in the Modular integrated Construction (MiC) buildings.
This laboratory “Laboratory for Adaptive Tubular Structures” under the auspices of The Chinese National Engineering Research Centre for Steel Construction (Hong Kong Branch) will integrate the simulation-based engineering science and use of testing methods for the understanding of the structural behaviour and design of tubular composite structures under various loadings. It will also focus on the development of new connection technologies such as interlocking and demountability for reuse and sustainable construction environment. Key research projects include (i) developing adaptable and demountable blind bolt solutions; (ii) structural characterization of high strength steel polygonal sections; (iii) interlocking and tubular joints between high strength steel sections in MiC buildings & (iv) seismic and progressive collapse analysis of MiC buildings with tubular members.

Lab details
This laboratory integrates the simulation-based engineering science and use of testing methods for the understanding of the structural behaviour and design of tubular composite structures under various loadings (multi hazards). It will also focus on the development of new connection technologies such as adaptable blind bolt solutions for reuse and sustainable construction environment. Some key projects include:
(I) developing adaptable blind bolt solutions;
