Optimization and compressive behavior of composite 2-D lattice structure

Abstract

In an effort to optimize axially compressed members of a wooden structure, composite 2-D lattice structures were designed and manufactured with wood-plastic composites as the panel and glass fiber reinforced plastic as the core by using a simple insert-glue method. The compressive behavior of composite 2-D lattice structures made of cores with different diameters and inclination angles was investigated. Analytical models were employed to predict the theoretical load capacity, equivalent compressive strength, and failure types of lattice structures. Reinforcing hoops were then made at the two ends of cores according to its force characteristics and failure type.
