Abstract

Based on an internally interlinked concept of space design, poplar LVL and oriented strand board (OSB) as panel respectively and mongolica sawn timber as truss member, gluing approach is adopted to combine truss members into single truss for core structure in this paper. There are four categories of prepared lattice sandwich structure of wooden truss, including lattice sandwich structure of poplar veneer synclastic truss, lattice sandwich structure of poplar veneer incongruous truss, lattice sandwich structure of OSB veneer synclastic truss and lattice sandwich structure of OSB veneer incongruous truss; nodes of prepared lattice sandwich structure for wooden truss are reinforced with bidirectional carbon cloth. The loading method of three-point bending should be adopted to test the bending properties of these four wood-based truss lattice sandwich structure and compare and analyze the rationality of material selection and structural design for the purpose for selecting the lattice sandwich structure for wood-based truss with optimal bending performance. The experimental results show that: Lattice sandwich structure for poplar veneer truss is superior to that for OSB truss in bending performance; lattice sandwich structure for incongruous truss with the same panel material overmatches that for synclastic truss in bending performance.
