Empirical evaluation of structural frame performance criteria: realizing the potential of hybrid concrete construction

Despite its enormous potential to improve performance, hybrid concrete construction (HCC) is currently underutilized. To demonstrate the benefits of using HCC (sometimes referred to as “mixed” construction) within the industry, it is essential that transparent criteria to assess this structural frame type against alternatives be determined, defined, and evaluated. Following a thorough review of literature in the building performance domain, a survey of U.K. experienced practitioners including clients, engineers, architects, quantity surveyors, and main contractors was conducted to obtain their perceptions regarding the importance of structural frame performance criteria (SFPC). A factor analysis of SFPC revealed seven dimensions, interpreted as “physical form and space,” “construction process,” “long-term sustainability,” “establishing confidence,” “building impact,” “physical appearance,” and “client satisfaction.” These dimensions should improve the decision making process when selecting an appropriate structural frame during early project stages by providing a simple list of performance criteria to be considered. Although these SFPC and dimensions were originally developed to ensure that the benefits of using HCC were apparent during the frame selection process, they are equally applicable to all frame choice comparisons. As such, they may provide a valuable tool for ensuring added value and client satisfaction.
