Study On Rationality And Energy-saving Of Bionic Building Structure

Bionic building is a close to nature,in line with the laws of natural science in the form of architectural structure.Because of its clever design,unique appearance,reasonable structure and energy conservation advantages,in today's huge energy consumption,resource shortages and serious pollution in the community is widely used.The research on the rationality and energy saving performance of the bionic building structure has great significance and application value for the construction of the beautiful homeland for human beings.This paper starts with the structural system of bionic architecture.Through access to existing research literature and field research,summed up a variety of structural types of bionic buildings,it is concluded that the structure type of the bionic building is closely related to the function.Among them,the tree structure is mainly used in transportation construction,membrane structure is mainly used in sports construction and small traffic construction,thin shell structure is mainly used in exhibition buildings.In order to analyze the structural rationality and energy saving of bionic buildings,this article selects ANSYS software,Based on the construction of Xi'an North Railway Station,the design of ordinary columns and one,two,three fork column four different programs on the rationality of the structure and energy efficiency simulation analysis,it is more reasonable to choose the structure of the secondary bifurcation column,and the energy saving is better.In the engineering design,in order to avoid too much bifurcation of the tree column lead to increase the internal force should be used as little as possible three-stage bifurcated tree column;The paper analyzes the rationality and energy saving of the structure from three different thicknesses,different angles and different materials,it was found that the structure of the thin shell with 140 mm thick was more reasonable and the energy saving was better.In the engineering design in order to avoid accidental factors within the structure of the internal force becomes larger and increase the structure of the insecurity,should be used as little as possible the angle of the shell structure program.In order to further study the overallenergy-saving effect of bionic buildings.In this paper,the unique structure of the membrane,the single and double layer of the structure of the comparative analysis,taking the "Water Cube" building as an example,the energy consumption simulation analysis is carried out by using DeST-c software,and three model schemes are set up to simulate and compare with the actual building.The study shows that the energy saving of the "Water Cube" project is better,indicating that the membrane material has more influence on the energy efficiency of the whole building.In summary,Its unique advantages and the use of new energy-saving technologies have certain application value and great prospect in the future design and construction of bionic buildings.
