Parametric Design And Optimization Of Large-span House Structural Form

Nowadays, the architectural designing field is more and more diverse、parametric、informatization、ecologicalization and coordinated, which is so differentfrom the traditional one. In this situation, the long-span buildings that is represented bythe sports buildings was so deeply influenced. It shows the characters of pioneer spiritand experimention. As the digital technology using much more widely and deepeningin the field of architectural design, we also begin to have new opportunities inexploring the long-span structures for new designing methods.In this article, research has focused on parametric modeling and optimizationanalysis of the long-span architecture in the means of parametric design method. Inorder to break the shackles of the conventional parametric study who is only aimed atthe study of the epidermis and overcome the difficulty in the architectural design oflarge-span structures who has more complex situations in selection and optimization,new methods will be discussed combining the advantages such as integrity, overall,adjustable of the parametric design. Here, the parametric design method is not agimmick attracted the eye to, not a so-called pioneer and trends slavishly, it is ainnovative platform for the traditional design and it has a new interpretation for thecollaborative design concept.This article first studys the problems of the modern long-span buildingstructure design, and a certain sum of the parametric design development. Combine thestrengths and weaknesses of the two theoretically, cut from both emotional and rationalway, explore different footing and starting point to build up a gradual application ofthe theory of complex digital platform. On this basis, large span buildings structuralforms often usded such as arch structure, shell structure, the basic form of grid trussstructure have been construction simulated. Initially build up a long span structuresparametric modeling and analysis of the basic processes, and verify that the platform isfeasible and effective.Finally, using the combination of design on commonly used long spanstructures through stadium instances. On the whole, his process can be divided intotwo parts:large-span building structures and construction process analysis andoptimization. The construction process can be subdivided into three parts: structuralparameter extraction, structure of the various parts of the mid-construction, lately thestructural combination. Analysis of the optimization process can be compared from thevertical and horizontal contrast two directions expanded. Through the studies of theselection of large-span structures parametric simulation and optimization to explore new ideas of the design in long-span building, It will have a certain significance in thefuture of the actual work.
