Optimization of Larch Timbering Cross Section Based on Finite Element





larch, availability, finite element, optimization


In view of the problem of the low utilization rate of larch as building materials, the cross-sectional dimension of larch wooden beams was optimized in this paper. The size of the larch wooden beam is 2000mm×80mm×80mm and the moisture content is 8.45%. By measuring experiments, The larch was statically analyzed by finite element softwareWith the volume of the beam as the target function, cross-section height and width as design variables, maximum stress and maximum deformation as state variables, and the results of static analysis as the state variable. Using these dates as the constraint of optimization design, the cross-sectional dimension of the larch wooden beam has been optimized as 2000 mm long, 55.02mm wide and 110.3mm high. The material was saved approximately 5.5% compared with that before optimization and improved the utilization efficiency of larch wooden beams in the construction industry.
