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...
متن کاملSeismic Displacement Demands for Hybrid Precast Concrete Shear Walls
This paper presents an analytical investigation on the peak lateral displacement demands of “hybrid” precast concrete panelized shear wall structures under seismic loading. The hybrid wall structure investigated uses a combination of mild [i.e., Grade 400 (U.S. Grade 60)] steel bars and highstrength unbonded post-tensioning (PT) strands for lateral resistance across horizontal joints. The analy...
متن کاملModeling of Dynamic Behavior and Estimation of Damage Incurred by Self-Centering Rocking Walls
Self-centering rocking walls are known as viable alternatives to typical shear walls, as they provide a number of solutions for eliminating seismic flaws of conventional designs. These rocking walls have a generally positive impact on the seismic behavior of structural systems, but their design makes them susceptible to concrete crushing around their base, which can lead to significantly advers...
متن کاملComparison of Hybrid and Emulative Precast Concrete Shear Walls for Seismic Regions
This paper compares the measured lateral load behavior of a 0.4-scale “hybrid” precast concrete wall test specimen with the behavior of a second precast specimen designed to emulate monolithic cast-in-place reinforced concrete shear walls. Both walls have the same overall geometry and are constructed by placing rectangular wall panels across horizontal joints. The lateral resistance at the join...
متن کاملComparison of Solid and Perforated Hybrid Precast Concrete Shear Walls for Seismic Regions
This paper compares the measured lateral load behaviors of two 0.4-scale “hybrid” precast concrete wall test specimens – one wall with solid panels and the other with perforated panels. The test specimens have the same overall geometry and utilize a combination of mild [i.e., Grade 400 (U.S. Grade 60)] steel and high-strength unbonded post-tensioning (PT) steel for lateral resistance across hor...
