Seismic performance of precast concrete wall with vertical energy-dissipating connection

Longji Dang et al.

Summary: A precast concrete wall with vertical energy-dissipating connection (PCWVEC) was proposed, featuring X-shaped metal dampers (XMD) for better energy-dissipating capacity and using pore-forming grouted lap-sliced connectors for longitudinal steel bars. Experimental tests and finite element analysis showed that the PCWVEC structure has good seismic performance, effectively transferring internal forces, dissipating energy, and providing self-centering and bearing capacities.

Seismic Behavior of Precast Buildings With Dissipative Connections

Lorenzo De Stefani et al.

Summary: Recent earthquakes in southern Europe have raised concerns about the importance of the connections of cladding panels to R.C. frames in precast buildings. This article evaluates the efficiency of dissipative panel-to-structure and roof connections in R.C. precast buildings, suggesting improvements in design methods and manufacturing technology. Results show that the proposed connection enhances the structural seismic performance, with the integration of efficient diaphragms being essential to prevent critical issues in precast structures.
