竹子对高层建筑结构设计的启示

The inspiration of bamboo to the structural design of high-rise buildings

随着施工工艺、建筑材料和建筑结构的不断发展,高层建筑在突破一个又一个高度极限,作为一个城市的地标性建筑,展现出结构之美。但是随着建筑高度的增加,潜在危险也在不断上升,很难兼顾结构的强度、刚度、稳定性以及结构扭转产生的负面效应,如果没有新的结构形式,很难有所突破。而自然界的生物经过千百万年的进化,与周围的环境相适应,结构“向优而生”。竹子作为又长又细的结构,与高层建筑结构相似,对建筑结构设计有着极大的参考价值,对竹子结构的合理性进行了分析,并结合具体工程案例对结构的仿生设计进行了详细阐述。

With the development of construction techniques,building materials and structures,high-rise buildings are breaking through height limit.As a landmark building of a city,they show the beauty of structure.However,with the increase of the building height,the potential danger of the building is also on the rise.It is difficult to take into account the strength,stiffness,stability and negative effects of structural torsion.Without new structural forms,it is difficult to make a breakthrough.After millions of years of evolution,the organisms adapt to the surrounding environment,the structure is rational.Bamboo,as a long and thin structure,is similar to the structure of high-rise buildings and has great reference value for architectural structure design.This paper analyzes the rationality of bamboo structure,and elaborates the bionic design of the structure in combination with specific engineering cases.
