Shear Performance of Horizontal Joints in Short Precast Concrete Columns with Sleeve Grouted Connections under Cyclic Loading
In this study, two short precast concrete columns and two cast-in-situ concrete columns were tested under cyclic loads. It was shown that the sleeve grouted connection was equivalent to the cast-in-situ connections for short columns when the axial compression ratio was 0.6. In order to determine the influence of the axial compression ratio and the shear-span ratio on the shear capacity of the h...
متن کاملSeismic Response of Reinforced Concrete Columns
There are a large number of reinforced concrete buildings in seismically active areas of the world that are not built in accordance with modern seismic design provisions such as those published by American Concrete Institution ([ACI] Committee 318, 2008). In the United States and other parts of the developed world, these buildings were constructed between 1930s to mid 1970s according to the bui...
متن کاملExperimental Study on Seismic Performance of Reinforced Concrete Frame Columns Supported with Post-build Wing Walls
Abstract: Six specimens of concrete frame columns reinforced by post-build wing walls on the opposite faces were designed and fabricated to investigate their seismic performance. Axial compression ratio was considered as the critical factor and divided into 0.31, 0.36, and 0.40 before reinforcement. HRB400 steel grade was used to the longitudinal bar and the ratio of longitudinal reinforcement ...
متن کاملDesign 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...
