Seismic design of multi-storey buildings using laminated veneer lumber (LVL)

摘要

The recent development of laminated veneer lumber (LVL) as analternative to solid timber or glue-laminated timber has greatly improved the viability ofstructural timber for the seismic design of certain types of buildings. The low mass,flexibility of design and rapidity of construction all create the potential for increased useof LVL timber in low-rise multi-storey buildings. Based on recent developments in theseismic design of precast concrete for multi-storey buildings, proposals are made forinnovative types of jointed ductile connections in LVL timber buildings, based on post-tensioningtechniques to assemble structural members for both frame and wall systems.This contribution gives an overview of an going comprehensive research projectinvolving both numerical and experimental investigations. The extremely satisfactorypreliminary results of quasi-static cyclic tests of exterior beam-column jointsubassemblies are presented as a confirmation of the expected high seismic performanceof the proposed solutions for LVL seismic resisting systems.
