Experimental Study on Seismic Performance of Concrete Composite Shear Wall with Self-Tapping Nail Connection
摘要
Abstract
The self-tapping nails connecting construction for prefabricated composite shear wall was proposed in this research.Three full-scale composite shear wall specimens were designed and tested by low cyclic experiment to study the seismic behavior of concrete composite shear wall with self-tapping nails connection.The shear span ratio of specimens was 1.39.The experimental variables included self-tapping nails connection,self-tapping nails and post-pouring belt connection,and L-shaped structural column.The failure modes,bearing capacity,hysteretic characteristic,stiffness degradation,energy consumption,and strain response were analyzed and discussed.The experimental results showed that the self-tapping nails connection had the advantages of good mechanical behavior and convenient installation.Compared with the specimen with self-tapping nails connection,the ultimate bearing capacity and initial stiffness of the specimen with self-tapping nails and post-pouring belt connection increased by 8.54%and 6.03%,respectively.Compared with the specimen without L-shaped structural column,the ultimate bearing capacity,initial stiffness and energy consumption of the specimen with L-shaped structural column increased by 67.48%,129.33%,and 277.93%,respectively.The concrete composite shear wall with self-tapping nail connection has good seismic performance that meets the seismic design requirement of prefabricated concrete composite shear wall residence building and it can be used in practice.关键词
