While columns and load-bearing walls keep buildings standing up, carrying the compression load of the structure down to its foundation, the shear wall is what keeps structures from blowing over, resisting the lateral forces of wind and seismic activity.

Basically, a well is a hole drilled into the ground to access water contained in an aquifer. A pipe and a pump are used to pull water out of the ground, and a screen filters out unwanted particles that could clog the pipe.

A retaining wall is a structure designed and constructed to resist the lateral pressure of soil, when there is a desired change in ground elevation that exceeds the angle of repose of the soil. A basement wall is thus one kind of retaining wall.

Retaining walls are structures designed to bound soils between two different elevations. … Many retaining walls are cantilever-type, but it’s also common to find in practice walls that are laterally restrained at the top, such as in the case of a basement retaining wall supported laterally by an elevated floor slab.

Post tension slab is a combination of conventional slab reinforcement and additional protruding high-strength steel tendons, which are consequently subjected to tension after the concrete has set. Strip footing is suitable when the soil, through expansive, little swelling pressure. When the soil swells, the sand grains would yield by moving up, thus reliving the swelling pressure. These

A pile cap is defined as a concrete block cast on the head of a group of piles, to transmit the load from the structure to the group of piles. Generally, pile cap transfers the load form the structures to a pile group, then the load further transfers to firm soil.

In buildings, free-standing walls are usually temporarily cantilevers, which are later propped by the adjoining floors. Common use of free-standing retaining walls is at highway underpasses. Free-standing retaining walls must provide their own stability against overturning and sliding.

Footings are the bases laid on the soil on top of which a structure is erected. Thus, it is the foundation on which a building or any such structure stands upon. … Before the foundation is built, a test is done to assess the strength ofthe soil bearing capacity to ascertain the type of foundation to

Concrete Floodway Design Apart from bridges and culverts, a flood crossing provides for flow over a road at a specific locationunder conditions determined by the designer. Flood crossings can be broadly divided into two types:• Causeway – a roadway across a watercourse or across tidal water, specifically designed toresist submergence.• Floodway – a roadway across

Sometimes an in-ground commercial flagpole isn’t a viable choice, due to sidewalks, building codes or other circumstances. … Shoe base poles are base mounted flag poles that are bolted to a concrete pad or base, much like a highway light pole.

The eccentric footing is a spread or wall footing that must resist a moment in addition to the axial column load, and it has the shape of the shoe. … When the allowable soil pressure is relatively high, and the distance between the columns is considerable, an eccentric footing is more economical than a combined footing.

A deep foundation is a type of foundation which is placed at a greater depth below the ground surface and transfers structure loads to the earth at depth. … However, when dealing with poor soil conditions at shallow depth, large design loads, and site constraints, a deep foundation is likely to be the optimum solution.
