under coThis task aims to evaluate and enhance the seismic performance of precast concrete walls and modular buildings, focusing on innovative design and analysis approaches. The objectives are:
- Characterization of the Seismic Behavior of Precast Walls with Dry Connections: Experimental and numerical studies to understand the impact of dry connections on the overall seismic response, including load transfer, energy dissipation, and deformation capacity.
- Seismic Behavior of Precast Modular Buildings: Comprehensive performance assessment through advanced nonlinear analysis methods, including static pushover and Incremental Dynamic Analysis (IDA), to evaluate collapse safety and damage progression under seismic loading.
Key aspects addressed include:
- The effect of connections on the global and local seismic performance, exploring different connection designs and their influence on structural integrity.
- Estimation of the behavior factor (q-factor) to quantify the ductility and overstrength capacity of the systems.
- Incorporation of core elements for additional stiffness and stability, with their contribution to the seismic behavior systematically analyzed.
The findings will provide critical insights into optimizing the design of precast modular buildings for seismic resilience, supporting safer and more reliable adoption of these systems in earthquake-prone regions.nstruction…
