DESIGN OF CANTILEVER STEEL SHEET PILE WALL

Sheet pile walls are a type of retaining wall that is often composed of steel, wood, or in the most limited cases, concrete structures. Steel piles are the most commonly utilized because they can be used on all types of terrain, at depths greater than 3.0 m, are watertight, and can be reused. Timber sheet piles are often less expensive than steel sheet piles, however, they can only be used for temporary buildings with a driving depth of no more than 3.0 m. Reinforced concrete sheet piles can only be utilized if they can be jetted into fine sands or driven into very soft soils. They are not ideal for rougher soils since they tend to break off when driven on.

Masonry is used to indicate the art of building a structure in either stone or brick. The masonry wall is built of individual blocks of materials such as stones, bricks, concrete, hollow blocks, cellular concrete, and laterite, usually in horizontal courses cemented together with some form of mortar. The binding strength of mortar is usually disregarded as far as the strength of the wall is concerned.

Masonry can be classified into the following categories:

- Stone masonry
- Brick masonry
- Hollow block concrete masonry
- Reinforced masonry
- Composite masonry

A spirally reinforced column has transverse reinforcement in the shape of spiral hoops. A tightly packed continuous spiral organizes the longitudinal reinforcement bars of the spiral column. Spiral columns are usually circular. Spiral reinforcement should be kept perpendicular to the line and firmly in place.
