A development length can be defined as the amount of reinforcement(bar) length needed to be embedded or projected into the column to establish the desired bond strength between the concrete and steel (or any other two types of material).

Reinforced concrete is used for construction on a large scale, such as bridges, dams, piers, tall buildings and stadiums. It is most commonly used in domestic construction for the footings and foundations of smaller everyday dwellings.

The design moment resistance of the base plate depends on the resistances of two T-stubs, one for each flange of the column. Whether each T-stub is in tension or compression depends on the magnitudes of the axial force and bending moment. The design forces for each situation are therefore determined first.
Base plate in compression. The resistance of concrete in compression is defined according to EN 1993-1-1 by the following formula. A temporary form representing the base of a denture; used for making maxillomandibular (jaw) relation records or for arranging artificial trial placement in the mouth to ensure exact fit of a denture.

corbel is a short cantilever projecting out from a column, a wall, or the side of a beam. … ACI 318 restricts the term “corbel” to a member having span-to-depth ratio which is less than or equal to 1.0. Corbels are widely used in precast concrete construction.

A load calculation is the process of determining the proper size of a furnace and/or air conditioner for a home. In the early days of the industry, hvac companies made an educated guess to determine the heat gain and loss for the home.
The design of beam includes the estimation of cross section dimension and reinforcement area to resist applied loads. There are two approaches for the design of beams. Firstly, begin the design by selecting depth and width of the beam then compute reinforcement area.
The two-way slab is a slab which is generally supported on all sides of walls or beams, and whose length to breadth ratio is less than two and it twists or bends in both direction while transferring the loads to the walls or beams.

A stair flight is a run of stairs or steps between landings. A staircase or stairway is one or more flights of stairs leading from one floor to another, and includes landings, newel posts, handrails, balustrades and additional parts. Flight. It is a continuous series of steps in one direction,, separated by horizontal platforms or winders. Landing.

AXIAL COLUMN SHORTENING In tall buildings, columns carry huge loads which effectively compress the column along its axis. This is commonly known as ‘axial shortening’. The axial column displacements generate significant forces within the structural elements they support, and can also cause failure of surrounding non-structural elements.

Circular Column: Circular columns are mostly used in piling and elevation of the buildings for aesthetic purposes. In a circular column, more than 4 longitudinal steel bars are used as a reinforcement bar and its bending resistance is generally higher than the square or rectangular column.

Introduction Eccentrically loaded reinforced concrete columns are commonly exist in practice due to the existence of some bending moments. The eccentricity of the supported beams as well as the unavoidable imperfections of construction are the main sources of the developed bending moments in the columns under gravity loads. In addition, lateral loads due to wind
