Design of Rectangular Openings in Precast Walls Under Vertical Loads

response of coupled-precast shear walls subjected to cyclic loads

large panel precast structures are analyzed based on the connection rigidity. however, the connections undergo nonlinear and inelastic response, when subjected to seismic loads. thus, to study the actual behavior of structure, the connection nonlinearity should be implemented in the joints. in this paper, three conventional connection types are modeled based on the envelope of their cyclic resp...

Design of Hybrid Precast Concrete Walls for Seismic Regions

This paper presents an ongoing research project on the behavior and design of “hybrid” precast concrete wall structures for use in seismic regions. Hybrid precast walls utilize a combination of mild (e.g., Grade 60) steel and high-strength unbonded post-tensioning (PT) steel for flexural resistance across horizontal joints. The mild steel reinforcement is designed to yield in tension and compre...
