Is a column a fixed support?

No, the support condition at the base of the building is not always considered as fixed. The structural engineer decides what is the best support condition. In most monolithic reinforced concrete buildings, the column bases are indeed fully fixed.

What is the difference between fixed and pinned support?

A pinned end can resist both vertical and horizontal forces but not a moment. They will allow the structural member to rotate, but not to translate in any direction. Fixed end can resist vertical and horizontal forces as well as a moment.

What is a pinned end?

Buckling (Pin Ended Columns): Force P that is applied through the centroid of the cross section and aligned with the longitudinal axis of the column. Force P is guided such that P is always aligned with the pin joints 3. Both ends of the beam are free to rotate about one or more axes.

What is a pile cap and what is its purpose?

A pile cap is a thick concrete mat that rests on concrete or timber piles that have been driven into soft or unstable ground to provide a suitable stable foundation.

What is a pinned support?

PINNED SUPPORTS A pinned support can resist both vertical and horizontal forces but not a moment. They will allow the structural member to rotate, but not to translate in any direction. Many connections are assumed to be pinned connections even though they might resist a small amount of moment in reality.

What is a fixed column?

Fixed columns, when they exist in a table, are always visible and are separated from the other columns by a vertical orange line. Fixed columns do not scroll off the page, regardless of how far the table is scrolled in either direction. Tables do not necessarily need to be loaded with fixed columns. …

What is a fixed connection?

Rigid, stiff or fixed connections lie at one extreme limit of this spectrum and hinged or pinned connections bound the other. The stiff connection maintins the relative angle between the connected members while the hinged connection allows a relative rotation.

What is a fixed support?

1. Fixed Support. A fixed support is the most rigid type of support or connection. It constrains the member in all translations and rotations (i.e. it cannot move or rotate in any direction). The easiest example of a fixed support would be a pole or column in concrete.

What is pin joint in column?

A pin connection works essentially like a lapped joint. It transfers vertical and horizontal shear loads and cannot resist any bending or moment (rotational) forces. This base connection for a support column at Calgary Water uses a pin connection.

What is the pinned connection?

A pinned support can resist both vertical and horizontal forces but not a moment. They will allow the structural member to rotate, but not to translate in any direction. A single pinned connection is usually not sufficient to make a structure stable.

Where is pile cap used?

Pile caps create a stable foundation and offer a larger area for the distribution of the building load onto the piles. They act in a similar way to piled raft foundations, where a concrete slab rests on soil which may be susceptible to movement, above a group of piles.

What is a pile cap explain the function construction process and types of reinforcement in a pile cap?

The pile cap is a mat-like structure which rests on the group of piles to transfer loads from the super structure. By IS 2911-2010, the pile cap could be arranged that the column’s load is spread at 45° out of the top of the cap.
