The independent super high-rise building weakens and reduces the cooperation of functional subsystems. Implanting aerial courtyards could improve the aerial environment of that corresponding floor and enable the plane courtyards to be stereoscopic. Constructing multiple aerial courtyard-centred functional clusters of higher floors can optimise the overall space structural relationship. The paper uses the space syntax theory to discuss how to construct holistically linked aerial courtyards in a super high-rise building and applies the Grasshopper-based space syntax arithmetic logical unit to analyse and calculate the aerial courtyard of super high-rise building in different space structure modes, and also proposes design optimisation strategies based on these analyses. The paper points out that by setting aerial courtyard between vertical transportation space and functional space, establishing a direct connection between adjacent aerial courtyards, arranging vertical transportation space dispersedly and so on, it is possible to promote vertical cooperative effect, enhance integration and intelligibility of entire space structure, and provide guidelines and foundation for the construction of vertical cities.
Traffic flow characterizes vitality in commercial clusters, and the accurate prediction of traffic flow based on the street network has significant implications for street planning and vitality regulation in commercial clusters. However, existing studies are limited by certain problems, such as difficulty in obtaining traffic flow data and carrying out technical methods. The purpose of this study is to use urban physical data to study traffic flow so as to quickly and effectively estimate the traffic flow in commercial clusters. This study takes the street networks of 100 commercial clusters in China as the research objects and classifies them into three forms according to the theory of “A city is not a tree”. Taking typical commercial clusters in these three forms as the research unit, space syntax was used to study five metrics of street network connectivity, and integration (Dn) was selected as a proxy variable for street network connectivity. The results show that the traffic flow in the three forms of commercial clusters can be predicted using the multiple regression models established based on the three metrics of integration, the traffic level, and the operation cycle. This study establishes the connection between the street network form and the traffic flow, which enables the possibility of obtaining the traffic flow of commercial clusters quickly and effectively. For areas with poorly structured urban data, the results can help urban planning administrators to predict the potential economic attributes using easily accessible street network data in commercial clusters.
Computer simulation technology has changed the traditional process of comparison and selection of architectural design schemes. Unlike the traditional process, which relies more on the experience of architects, computer algorithms can realize the calculation of quantitative indicators for complex problems and provide objective basis for scheme comparison and selection. Combined with the application of engineering projects, this article expounds the application of computer-aided design in architectural design through the method of calculating visibility percent of quantitative indicators to judge the visibility of the interior display space design in small shopping centres by multi-software simulation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
