Building Technology Forecast and Evaluation (BTFE). Volume 2: Evaluation of Two Structural Systems.

摘要

Volume I of this report described the BTFE cycle and demonstrated its use in performing the first three phases in a practice exercise. This application yielded two structural systems with potential advantage to the U.S. Army Corps of Engineers: tunnel forming systems and composite panelized systems. Volume II describes the detailed evaluation of these two systems. To perform these analyses, it was necessary to further develop the evaluation procedure that Volume I explained in general terms. For the two systems identified, this process has to be adapted specifically to assess structural systems. General performance attributes related directly or indirectly to structural performance were identified. For each attribute, specific subattributes were selected to describe the structural performance more elaborately and explicitly. Design and construction criteria used to define these specific attributes were referenced to USACE and Department of Defense Specifications as well as to industry standards. The resulting evaluation process thus has an objective (quantitative) component that includes the tangible data related to design construction, experimentation, etc., and a subjective (qualitative) component that includes interview information (e.g., expert opinions) and published material.
