Sun-guided Nonlinear Architectural Design Method

With the development of economy and technology,nonlinear architectural design springed up like mushroom in the modern world.The architectural design method under the guidance of "nonlinear"relationship shows more complexity and variability than traditional linear architecture,and its shape design tends to be diversified.However,most of the nonlinear design carried out by present architects just stay on the surface by subjectively kneading the building shape,ignoring the inherent logic and value of nonlinear design.This makes this kind of architectural style result sustain more criticism.Wsith the development of the times,the capacity of cad technique is becoming more and more perfect,which is gradually trending to change from aiding design to orienting design.Based on theory of nonlinear parametric technology and the computer aided analysis technology we can weigh the shape of a building using a variety of intelligent optimization algorithm,with a process of basic elements "emergent" we can generate more reasonable building shape,and then as a direction to guide design.Sunlight factor plays a important decisive role in architectural design,especially in shape design.The traditional "square box" linear building can only response to sunlight in a inefficient and limited way.However,the combination with nonlinear architectural shape allows us to jump out of this limitation and achieve the maximum possible utilization of sunlight.Based on the current theoretical and philosophical arrangement related to nonlinear design,this paper firstly confirms the nonlinear essence of the world and the rational and applicable basis of the nonlinear design method from the theoretical perspective.Then in combination with this rational model,this paper discusses the design process from the perspective of interdisciplinary digital architecture.At the same time,the difference of operational logic between the current popular genetic algorithm and other algorithms is considered,so as to get rid of the limitation of architectural algorithm selection.Combining the architectural shape making process with genetic algorithm,annealing algorithm and particle swarm optimization algorithm,this paper then discusses various aspects related to building shape based on sunshine elements,and puts forward an optimal design process for architectural shape making process based on algorithm generative model.Furthermore,it provides some theoretical support for the shape design of nonlinear architecture and theoretical basis for subsequent research and practice.
