| In recent years,raw bamboo,as a low-carbon,environmentally friendly,renewable,and culturally bearing construction material has attracted more and more attention,and related engineering projects and construction competitions have shown a clear growth trend.On the one hand,the original bamboo building benefited from the ability of parametric tools to express complex shapes and the ability of original bamboo to be easily bent.The shape of the original bamboo continues to develop to free form,curved structure,and spatial structure.Architects rely on experience to determine its structural performance More and more difficult;on the other hand,the original bamboo building has gradually developed into a permanent building with a larger span,roof covering,and certain requirements for wind and snow loads.This has greatly increased the requirements for the structural performance of the original bamboo building..In many cases,due to the uncertainty of structural performance,architects can only guarantee the structural performance of raw bamboo buildings by adding consumables,resulting in the construction results deviating from the design expectations to varying degrees.Under this contradiction,the original bamboo architectural design that emphasizes structural performance orientation becomes more and more urgent.This research is mainly from the perspective of digital structural performance design.In the basic method of structural performance design,the original bamboo material,structural system,construction method and other special attributes are improved,and a set of structural performance-oriented raw bamboo parameterization is proposed.Design method.The whole design method is mainly divided into four steps: judgment of original bamboo structure system,basic shape generation,component shape generation,and form optimization.The judgment of structural system mainly emphasizes the adaptability of structural system to the idea of "active form finding" in structural performance-based design or "passive optimization" in general parametric design.The generation of basic form is based on the idea of "active form finding" and "passive optimization" respectively,and the design of architectural form is inversely deduced by solving the ideal force transfer state according to the idea of "active form finding" and "passive optimization" Methods: the component shape generation uses the formulaic algorithm to accurately restore the shape attributes of the original bamboo components to avoid possible errors;Form optimization also uses the finite element analysis method to accurately restore the shape,mechanics,and node attributes of the original bamboo to calculate the structural performance of the building,providing accurate data support for the optimization of the form.Through in-depth research on the special properties of raw bamboo buildings,the neglected or unmanageable properties are refined and regularized,helping architects to quickly understand the characteristics of raw bamboo materials,structure,and structure,and realize building form and structural performance The parametric design of the original bamboo building is highly unified and precisely controlled from design to construction.The original bamboo architecture is in a stage where engineering practice has increased greatly,and the related research has not been fully developed.There are still many areas for in-depth exploration in the theoretical system of original bamboo architecture. |
