How do you terminate a column?

Place your cursor where you want the column to break. Click Layout > Breaks. In Word 2013 or Word 2010, click Page Layout > Breaks.

Why are bars bent at end?

We bend the bars in beams at the end, so that they can act as an hook and provide Anchorage to the beam at the ends. In most of the cases we get negative BM at supports (circle2&3),to resist this BM, bottom main bars are bent to top(circle1) and to resist the maximum SF(circle4).

Why are column bars offset at the top?

One reason for this practice is to simplify fabrication of the top-most longitudinal bars in a column, which could have an offset bend at one end (the bottom end) and a 90-degree hook at the other end (the top end). Another reason is due to typical floor-to-floor construction techniques used to construct buildings.

Why do columns need reinforcement?

Providing reinforcement in columns effectively ties them with beams. Without reinforcement, the size of columns will increase to some extent. Reinforcement steel enhances the ductility of the member and the structure shall resist earthquakes better.

What is column break?

A column break places a hard break, much like a page break or section break, in the inserted location and forces the rest of the text to appear in the next column. In a document that includes columns, place the cursor where you want the column to break.

What is difference between Main Bar and distribution bar?

Main Reinforcement Bars are used to transfer the bending moment developed at the bottom of the slab. Distribution Bars are used to hold the slabs on either way and to resist the cracks and shear stress developed at the top.

Why do we bend bars?

Thanks for A2A. Bent up bars are the main reinforcements bent at a suitable angle to act as shear reinforcements. Reinforcements are bent up to the supports/ends where greater compressive force occurs. Mainly to resist shear force at supports.

What does an offset in column rebar do?

Offset bent longitudinal reinforcement is the bending of vertical reinforcement bars of a column (larger column) at a particular storey in order to bring the bars within the limit of a above (smaller column), as illustrated in Fig.

What should be the slope of reinforcement bar at reduced column?

While lapping/splices column rebars, it should be ensured that the connecting rebar is given a slope of 1 in 6 (minimum) such that the centre line of each rebar coincides. Lapping should preferably be done in the centre part of column with a lap length of 57 times the diameter of rebar.

Why column is needed?

Columns are frequently used to support beams or arches on which the upper parts of walls or ceilings rest. A column might also be a decorative element not needed for structural purposes; many columns are engaged, that is to say form part of a wall.

What is column rebar?

Column is a vertical compression member which transmits load of the structure to foundations (Fig 2). They are reinforced by means of main longitudinal (vertical) bars to resist compression and/or bending; and transverse steel (closed ties) to resist shearing force (Fig 3).

What are column columns in reinforcements?

Columns are essentially required with the primary longitudinal reinforcement and lateral ties to avoid buckling of the primary bars. The details of minimum and maximum limits of reinforcements, minimum no. of bars, the size of bars, cover requirements, diameter, and spacing are given in the above picture.

What are the requirements for reinforcement bars in a beam?

The reinforcing bars must have the required development length at any point in order to take up the stresses imposed on them. Hence if the beam reinforcement is required to take up stresses at its ends, the bar must be continued beyond its end into either the adjoining beam or the supporting column.

Why do column bars have to be anchored in the beam?

This applies to top bars as well as bottom bars of a beam which has been designed to resist seismic or wind stresses which cause stresses alternately at top ends as well as at bottom ends. Similarly the column bars must be anchored into the beam joining with the column, for the required length.

What is the maximum limit of reinforcement in a column?

In column min tension reinforcement is 0.8\% and Maximum limit is 6\% of total cross sectional area of column if bar As per IS 456:2000 In SLAB as per Clause 26.5.2.1 Min reinforcement shall be 0.15\% of total cross-sectional area for mild steel bars and 0.12\% of total cross-sectional area for HYSD bars.
