Rule of Design and Construction for Concrete Structures based on the Performance-creative Design Concept
By S. Ikeda
Concrete Journal, Vol.49, No.11, Nov. 2011
- Synopsis
- The author has been proposing a new philosophy of design concept for concrete structures named performance-creative design method. Recently, various structural performances should be verified according to the specific design code. This trend has invited the design attitude of the verification of structural performance, say, performance-verification design method. However, the author has felt that the philosophy of design should be more active and creative in manner rather than the verification for a given structural system. Here, the author pointed out the contradiction of the terminology in the coined Japanese words of "subjective" and "objective" which are essential concept to express creativity. Construction of structures in the society is the construction of artificial environment. Therefore, creativity in the design of structural concrete is inevitable to construct and maintain an attractive society. Japan Prestressed Concrete Engineering Association stipulated an entirely new rule for concrete structures based on the performance-creative design concept and has published it in September 2011. In this rule necessary function of the structure is first determined as a subject and then the structure is realized creatively to get the object.
