ABSTRACT:
A lateral force resistance device for a ground achoring system suitably used in expansive soils has an inner sleeve structure and an outer collar connected to the inner sleeve structure by a plurality of load transfer members such as longitudinal load transfer plates. The lateral force resistance device is embedded in the soil over a ground anchor, such as a helical anchor, by sliding the inner sleeve structure of the device over the top end of the anchor and using an embedment method involving vibration, pushing or other technique. The outer collar of the lateral force resistance device provides a relatively large surface area displaced from the inner sleeve structure for providing efficient load transfer to the surrounding soil.
