description: This thesis focuses on the exploration of a now-popular performance-based design approach - Direct Displacement-Based Design (DDBD), its application in the de- sign of new structural archetypes, non-linear static and dynamic analysis of these structures, and their seismic risk assessment. First, this study sought to validate a modified direct displacement-based design procedure for post-tensioned timber structures fitted with dissipative bracing systems, after which an Opensees numerical model to simulate the behaviour of the designed frame was validated by calibrating the hysteretic behaviours of the numerical models with results from an experimental model which was tested during the development of this modified direct displacement-based design procedure. After the validation of this modified direct displacement-based design procedure and the Opensees numerical model, the concepts were extended to a 6-storey post-tensioned mass timber building fitted with dissipative bracing systems. A numerical model for this 6-storey structure was created in Opensees and subjected to static and dynamic non-linear analysis using 60 bi-directional spectral compatible ground-motion records from PEER and KiK-net databases to test the accuracy of this new direct displacement-based design procedure. The results affirm the accuracy of this modified direct displacement-based design procedure for post-tensioned mass timber structural systems fitted with dissipative bracing. Next, this thesis focuses on the Opensees numerical modeling, static and dynamic non-linear analysis, and seismic-risk assessment of a hybrid reinforced concrete cross-laminated-timber structure (RC-CLT) which has already been designed using direct displacement-based design procedure. The non-linear dynamic analysis was carried out using a set of 40 hazard-consistent ground motion pairs selected from PEER and KiK-net databases, and reflect the recently developed 6th generation seismic hazard model of Canada (SHM6).
