Seismic Performance Study of Fabricated High strength Reinforced Concrete Shear Wall Horizontal Connection Seam
Block prefabricated shear body and connected to form two types of nodes: one is the shear vertical connecting node, namely, the lower connecting precast shear walls; the other is the level of shear wall connecting node that is connected with the pre shear layer adjacent to the non shear and between precast shear walls or with an adjacent layer. Under horizontal earthquake, prefabricated shear vertical connecting node will be directly involved in stress and deformation. Since the horizontal seam to weaken the shear plane, if not handled properly connected measures, it can easily become the weak parts of shear walls, and even affect the overall structural performance. To understand the power transmission mechanism prefabricated shear horizontal seam structure, energy dissipation mechanism and seismic performance, reliable and exploring measures to improve or perfect the various prefabricated ability to work together to improve the structural integrity and seismic performance, prefabricated vertical shear connection has been completed based on the seismic performance of the test, carry out a new connecting node structure prefabricated shear wall structure horizontal seam, by conducting relevant tests, finite element methods and theories analytical tools, be horizontal shear wall structure evaluation and design method of prefabricated joints seismic performance.
