Multi-criteria decision analysis of timber–concrete composite floor systems in multi-storey wooden buildings

This study aims to present a multi-criteria decision analysis (MCDA) for comprehensive performance evaluation of the alternative design timber–concrete composite (TCC) floor system. Considered objectives are serviceability and sustainability with associated criterion as (1) comfort class regarding springiness vibrations, (2) architectural quality open spaces, (3) environmental aspect CO2 emissions (4) cost total costs. Analytical Hierarchy Process (AHP) Complex Proportional Assessment (COPRAS) methods in have been combined determining weighting criteria based on survey results, verifying consistency ratio matrix made by experts ranking selecting optimal concept among candidates. According TCC span length 7.3 m belonging A has got highest ranking. However, sensitivity indicates that 9.0 shall be selected design. The contributes developing complete tool systems using AHP COPRAS handle both beneficial non-beneficial criteria.
