Abstract

Conceptual structural design of tall buildings consists of selecting structural materials and form of a building and producing a preliminary dimensional layout. Key parameters of a building, such as height of the building, typical live load, wind velocity, design acceleration, maximum lateral deflection, span, and story height, are important factors in the conceptual design phase. Knowledge solutions from similar problems in the past can be used for defining and finding a solution to a design problem. CBR(Case-based reasoning) is a problem solving approach that uses past experience and is highly useful to finding solutions for similar problems.

In this paper, the conceptual structural design method using CBR which is intended to assist engineers in the schematic phase of the structural design of tall buildings is introduced. Inductive retrieval method and nearest-neighbor retrieval method are used for selecting structural system and similar design case, respectively. This study presents a schematic design method based on CBR using design information of tall building as a solution for the preliminary conceptual design stage.
