Digital technology provides a standardised and systematic operation for the creation of new wooden structures.This study takes the design of"umbrella shaped"and"beam column"wooden structures as research samples.The building model is parameterised using the Grasshopper platform and the force transmission method is analysed and visualised using finite element analysis.Genetic algorithm is used for multi-objective optimisation to find the optimal solution for the structural form and to construct a parameterised generation model.Based on the example model,this paper analyses the principles and methods of wooden structure design from three aspects:umbrella shaped structural units,beam column overall framework and wood mesh weaving texture.It also discusses the materials and detailed technical strategies,coordinates the relationship between conceptual design,materials and construction,and expands the possibilities of wooden architecture,in order to provide inspiration for the current design of wooden architecture in China.
