Horizontal Loading Tests on Disconnected Piled Rafts and a Simplified Method to Evaluate the Horizontal Bearing Capacity

Table 1

Summary of previous studies on piled raft foundations subjected to a static horizontal load and this study.

	Loading condition	Condition between raft and pile head	Pile length (mm)	RVLP (%)	Foundation type tested
Hamada et al. [13]	Vertical load	Rigidly connected	700	45–82	R, PR, PG
Hamada et al. [14]	Vertical load	Rigidly connected	700	58–82	R, SP, PR, PG
Sawada et al. [15]	Vertical load	Rigidly connected	160	27	R, PR, PG
Nakai et al. [16]	Dynamic load	Connected and disconnected	180	0–100	PG, PR, DPR
Matsumoto et al. [17–18]	Vertical load	Hinged and rigidly connected	170	9.6–42.8	PR
Horikoshi et al. [19]	Vertical load	Hinged and rigidly connected	180	60	R, PR, SP
Pastsakorn et al. [20]	Vertical load	Rigidly connected	200	8.7–42.4	PR, PG
This study	Horizontal load	Disconnected	400	72–100	R, DPR

Note. RVLP is the proportion of the vertical load carried by the raft; R is the raft; PR is the piled raft; PG is the pile group; SP is the single pile; DPR is the disconnected piled raft.
