Synopsis
This paper looks at the possibility of using cross-laminated timber (CLT) construction to support commercial buildings to 30 levels. A prototype building structure is proposed and analysed using an elastic analysis program. The main structural elements, including a central tube core, columns and beams, are made of cross-laminated timber. The CLT panels are arranged to ensure structural efficiency with minimal material wastage. The CLT central core is assisted by steel stays (like those of a yacht), and reinforced concrete beams which act like wine barrel hoops. Consideration is given to the design of simple but stiff joints. The structural elements are examined for strength and the building deflections are noted. The paper concludes that the proposed structural system with CLT elements is likely to be suitable for buildings to 30 levels.
