Good seismic behaviour of prefabricated concrete structures is critical to ensure safe long-term performance of residential and engineering structures. Various connection specimens were fabricated, including three prefabricated reinforced-concrete (RC) shear wall and concrete-filled steel tubular column connections, and one reference cast-in-place specimen. Cyclic loading was used to study the effect of the number of shear connectors and concrete strength in a connection zone on the failure mode and hysteresis of the connection. All specimens failed due to failure of shear connectors, where most damage occurred at the connectors and in nearby concrete. When the number of shear connectors increased from 3 to 5, the bearing capacity of the specimens increased by ~35%, while the ductility and energy dissipation capacity also improved. Increasing the concrete strength in the connection zone did not improve significantly the bearing capacity or seismic performance. The bearing capacity of the cast-in-place specimen was similar to that of the equivalent prefabricated precast specimen. Slip between the connection zone and precast RC shear wall resulted in internal force redistribution, resulting in higher ductility and energy dissipation capacity of the prefabricated specimens. Finally, computational analysis of previous models identified the best model for simulating force-slip behaviour of similar connections.

预制混凝土结构的良好抗震性能对于确保住宅和工程结构的长期安全性能至关重要。制作了各种连接标本，包括三个预制的钢筋混凝土（RC）剪力墙和钢管混凝土柱连接，以及一个参考现浇标本。循环荷载用于研究连接区域的剪切连接器数量和混凝土强度对连接的破坏模式和滞后的影响。由于剪切连接器的故障，所有标本都失败了，其中大部分损坏发生在连接器和附近的混凝土中。当剪切连接器的数量从3个增加到5个时，试样的承载能力增加了约35％，而延展性和能量耗散能力也得到了改善。增加连接区域的混凝土强度并不能显着提高承载能力或抗震性能。现浇试样的承载能力与等效的预制预制试样的承载能力相似。连接区域和预制RC剪力墙之间的滑移导致内力重新分布，从而使预制标本具有更高的延展性和能量消散能力。最后，对先前模型的计算分析确定了用于模拟相似连接的力滑行为的最佳模型。连接区域和预制RC剪力墙之间的滑移导致内力重新分布，从而使预制标本具有更高的延展性和能量消散能力。最后，对先前模型的计算分析确定了用于模拟相似连接的力滑行为的最佳模型。连接区域和预制RC剪力墙之间的滑移导致内力重新分布，从而使预制标本具有更高的延展性和能量消散能力。最后，对先前模型的计算分析确定了用于模拟相似连接的力滑行为的最佳模型。
