Compression-Shear Behavior and Water Impermeability of Rubber Seal in Precast Concrete Structures

PRECAST CONCRETE SHEAR WALL CONNECTIONS USED FOR lYIEDIUM AND HIGHRISE STRUCTURES

The precast concrete shear wall system is becoming very popular in North America for low, medium, and highrise construction due to the economical advantages possible with the ease and speed of assembly, and the high quality of the precast panels. The connections between panels are extremely important since they affect both the speed of erection and the overall integrity of the structure. This p...

Development of a Skewed Pipe Shear Connector for Precast Concrete Structures

Joint connection methods, such as shear key and loop bar, improve the structural performance of precast concrete structures; consequently, there is usually decreased workability or constructional efficiency. This paper proposes a high-efficiency skewed pipe shear connector. To resist shear and pull-out forces, the proposed connectors are placed diagonally between precast concrete segments and a...

Experimental Study on Flexural Behavior of Precast Concrete Shear Walls with Vertical Joint

Seismic 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...

Connections for Precast Concrete Load-bearing Shear Wall Panels

Precast load-bearing shear wall panels are used extensively for high-rise construction because of the ease and speed of assembly, and the high quality of the precast panels. The connections between panels are extremely important since they affect both the speed of erection '~md the overall integrity of the structure. This paper presents the results of a four-year research program conducted to i...
