Therefore, it is important to understand the proper embedment length of the longitudinal reinforcement considering the interface behavior between the infilled concrete and the steel casing in the CISS pile.
In particular, the embedment length of the longitudinal reinforcement in the RC pier to the CISS pile (referred to as the embedment length for short) is selected as a key parameter.
The first is the required embedment length for the full function of the RC pier.
Those topics include: (1) embedment length, (2) pullout check, (3) eccentricity, (4) lateral pressures, (5) the equation for soil geosynthetic capacity for bearing resistance and required reinforcement strength, and (6) long-term geosynthetic reduction factors.
Embedment length refers to the length of reinforcement within the GRS mass.
When the embedment length
is too short then the fibre(s) is pulled out of the concrete with or without the surrounding matrix.
The anchor infill assembly studied in the presented simulation is a two-layer anchor infill assembly with the anchor bar radius of 19 mm and the anchor bar embedment length
of 20 time diameter of anchor bar db.
The fibre embedment length was mainly 25 mm, which is a half of the fibre full length.
Although the total pullout energy of fibres with embedment length of, for example, 25 mm, is greater for deformed fibres (hooked, crimped, flat-ended) than for smooth ones, the effect is intangible for relatively small slippage displacement.
The embedment length for the pull-out rebars were chosen as [l.
This volume was chosen as a cube with a side length equal to the embedment length of the pull-out rebar, i.
For a flexible anchorage embedment length
of 12 ft, the maximum elastic movement is
