Research On The The Open-air Theater Based On Beijing World Horticultural Exhibitions Performance Plaza

The open-air theater refers to the theater of which the performance field or the audience area is placed in the open space which does not have the complete enclosure structure and is directly open to the audience.As a special type of theater architecture,the open-air theatre interprets the most direct relationship between audience and actors which is the origin of modern indoor theater.Under the background of the era of the big theatre,the open-air theater is an important supplement to the performing space.At the same time,the vigorous development of the outdoor performance market and the growing city public performance behavior conflicts with the shortage of city space.The open-air theater is an effective means to solve this problem as a type of open space in city.The research first reviews several forms of theatre in the evolution of the open-air theater,and discusses its development status and trends.Then three main types are summed up.On the basis of the understanding of the development process and the main types,the research summarizes the core features of the open-air theater.The research compares the open-air theater with the urban outdoor public performing-spectating space which is the similar type in order to find the commonality.The step furtherly defines the concept of the open-air theater and reveals the significance of the research for the design of urban outdoor public performing-spectating space.The open-air theatre and indoor theater has the same nature of accommodating performance behavior.In order to refer to the mature design system of indoor theater,the research try to find the difference between the open-air theater and indoor theater,which can ensure that the summary of the key points is comprehensive and rational.The design of the World Horticultural Exposition Performance Plaza is carried out in the design environment in reality,facing budget,the professional coordination and communication of material manufacturers.The special characteristics of the project are supplements to the design framework of the outdoor theater.Based on the project,the comparison of the design framework and the practical scheme confirms the feasibility of the key points.At the same time,the design framework responds to various aspects of the actual project,which leads to the final design of the project.The design of World Horticultural Exposition Performance Plaza is not the subjective conception of architects but a design facing real conditions.There is no doubt the project has important reference significance for the practice of open-air theater.
