Seismic assessment of existing Italian RC precast structures

The paper presents a comprehensive seismic assessment of an existing single-story reinforced concrete (RC) precast structure, resembling the typical characteristics of Italian industrial facilities. For a more realistic evaluation, a simulated design is performed, accounting for old codes and seismic zonation. Then, state-of-the-art nonlinear models are developed in Open- Sees, considering or not the contribution of lateral cladding, made by masonry infills. Nonlinear dynamic analyses are performed, achieving a wide and accurate seismic assessment. Obtained outcomes highlights the main vulnerabilities of existing precast buildings in Italy, providing useful insights on their seismic behavior. Lastly, failure rates are evaluated and presented.
