Abstract

Abstract

In this paper， experimental studies were conducted on the mechanical properties of typical components of a practical prefabricated shear wall structure， including grouting sleeves， laminated reinforced concrete slabs containing joints， and joints between laminated slabs and prefabricated reinforced concrete shear walls. Industrial computerized tomography （CT） and pull-out tests were conducted on the grouting sleeves connecting the vertical rebars of the upper and lower prefabricated shear walls. It was found that the rebars were generally difficult to align in actual construction. However， the pull-out properties of grouting sleeves met the requirements. Static loading tests were conducted on the slabs. Both slab specimens showed good flexural ductility， and their experimental and calculated bearing capacity values were in good agreement. Quasi-static cyclic tests were conducted on the joints. The load-deflection skeleton curves showed an inverted S-shape， indicating good ductility and energy dissipation capacity. The bearing capacities and failure modes of all three types of components met the design requirements.
- prefabricated shear wall,
