| Abstract |
Hybrid precast concrete panel is a wall element that is able to quickly construct the core wall structure for moderate-rise modular buildings.
Hybrid precast concrete panel has unique characteristics which is a pair of C-shaped steel beams combined at the top and bottom of a
concrete wall, In this study, an improved anchorage detail for vertical rebar is proposed to ensure the lateral force resistance performance of
hybrid precast concrete panel emulating monolithic concrete wall. Also, the structural performance of horizontal connection is investigated
experimentally with the bolt spacing parameter. And the behavior of hybrid precast concrete panel with the improved detail is compared with
the monolithic concrete wall tested in a previous study. Finally, the required thickness of C-shaped steel beam to eliminate or minimize the
deformation in horizontal connection is calculated by prying action equation. |
