An intelligent decision-making model for the design of precast slab joints based on case-based reasoning

Shen, K; Zhu, Y; Pan, J and Li, X (2023) An intelligent decision-making model for the design of precast slab joints based on case-based reasoning. Journal of Construction Engineering and Management, 149(5): 04023025, ISSN 0733-9364

Abstract

Precast components are a critical part of the life cycle of prefabricated construction. Component joints and connections are essential to structural stability, posing rework problems. The design of precast component joints requires tacit and explicit knowledge. Existing joint design approaches and construction requirements underuse tacit knowledge. This paper proposes a case-based reasoning (CBR) model to support the design of component joints based on this tacit knowledge. A case library of 299 valid precast slabs was used to develop the model. The test cases in the model were used to verify the methodology. Records for 64 test cases with the same building information and 64 test cases from different buildings were used to validate the usability and effectiveness of the model. The results show that the accuracy rates are 100% and 94% when considering the comprehensive performance, and the model is more effective for different buildings than for the same building. The proposed model can improve the efficiency of joint design without expert participation and improve the standardization and coordination of design and construction.

Descriptive scope: 3 PCT

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
