Developing a Framework of a Multi-objective and Multi-criteria Based Approach for Integration of LCA-LCC and Dynamic Analysis in Industrialized Multi-storey Timber Construction
To improve organizational decision-making process in construction industry, a framework of a multi-objective and multi-criteria based approach has been developed to integrate results from Life-Cycle Analysis (LCA), Life-Cycle Cost Analysis (LCC) and dynamic analysis for multi-storey industrialized timber structure. Two Building Information Modelling (BIM)-based 3D structural models based on different horizontal stabilization and floor systems will be analyzed to reduce both climate impact, material and production costs and enhance structural dynamic response of the floor system. Moreover, sensitivity of the optimal design will also be analyzed to validate the design. The multi-objective and multi-criteria based LCA-LCC framework analyzing the environmental, economic, and dynamic performances will support decision making for different design in the early phases of a project, where various alternatives can be created and evaluated. The proposed integrated model may become a promising tool for the building designers and decision makers in industrialized timber construction.
