The Quantitative Study On Visual Balance Of Asymmetric Building Facade Based On Visual Sensitivity

Nature and form,the body will be double,god for use,things are not isolated.Symmetrical things are naturally balanced,but restricted by the actual conditions,the facade of the building adopts asymmetric balanced design in many cases.It is worth exploring whether some asymmetrical facades with good visual aesthetics contain some common visual laws.In view of the multi-disciplinary and comprehensive characteristics of architectural aesthetics,based on the visual sensitivity,this paper takes the asymmetric building facade as the research object and combines the relevant knowledge of architecture,visual science and psychology to conduct a quantitative study on the visual balance aesthetics of the asymmetric building facade.Firstly,by analyzing and summarizing the current situation at home and abroad,this paper points out main problems involved that are visual nonlinearity and model construction,to be solved in the study on the equilibrium quantization of the facade of asymmetric buildings based on visual sensitivity.Then around the problem,supplemented by MATLAB computing platform and Isovist perspective analysis,the aesthetic aesthetic of the asymmetric facade of the real world is constructed in an abstract quantitative model.The three basic elements of visual balance quantification for elevation are proposed,the discriminant experiment of spatial visual sensitivity is designed,and the spatial visual sensitivity equation is obtained by fitting the experimental data through the data analysis software 1STOPT.Based on two field experiments,the validity of the facade balanced quantization model is verified.Finally,the application of the quantitative model,the part in the history of the classic case for asymmetric building facade visual equilibrium calculation,mining facade equilibrium and visual center location,the intrinsic relationship between viewing Angle,elevation scale,refining some asymmetric facade design techniques.The paper submits a new set of visual balance quantization model and design method of asymmetric building facade,provides supplementary means for objective evaluation and optimization of design of asymmetric building facade,and summarizes asymmetric facade design visual balance technique with experiments and case analysis.Limited by the level of researcher,there may be a gap between the research results andthe actual visual equilibrium perception of asymmetric building facades.
