Experimental Study on Seismic Behavior of Precast Frame Columns with Vertical Reinforcement Spliced with Grouted Sleeve Lapping Connectors

Table 1

Comparison of two connectors.

Object	Casting process	Connector length (d)	Fault tolerance	Grouting defect	Construction schedule	Cost
Grouted splice connector	Complex	16	Low	Not dense	Normal speed	High
Grouted sleeve lapping connector	Simple	12.5	High	Dense	Fast	Low
