What is a lateral dimension?
adj. 1 of or relating to the side or sides. a lateral blow. 2 (Phonetics) (of a speech sound like l) pronounced with the tip of the tongue touching the centre of the alveolar ridge, leaving space on one or both sides for the passage of the airstream.
What is least lateral dimension of column?
Difference Between Short Column and Long Column
Sr.No. | Long Column |
---|---|
1 | Long column is considered to be long if the ratio of effective length of column to its least lateral dimension is greater than 12. |
2 | Long column is weaker than a short column and generally, it is not preferred. |
What is lateral dimension in column?
(c) Column: Column is a vertical compression member whose unsupported length l shall not exceed sixty times of b (least lateral dimension), if restrained at the two ends. (d) Wall: Wall is a vertical compression member whose effective height Hwe to thickness t (least lateral dimension) shall not exceed 30 (cl. 32.2.
What is unsupported length of a column?
The unsupported length of a column is the undisrupted distance between the floor and the lower beam. In order to get the effective length of the column, you have to take the effective stiffness factor and multiply by the unsupported length of the column.
When ratio of effective length and least lateral dimension is in between 3 to 12 the column can be designed as?
A short column is the one whose ratio of effective length to its least lateral dimension is less than or equal to 12. Then it is termed as a short column.
When the ratio of effective length of the column to it is least lateral dimension does not exceed 15 it is termed as?
compression member can be classified based upon the ratio of effective length to the lateral dimension of the column. If effective length to lateral dimension is less than 3, it is termed as a pedestal. If effective length to lateral dimension is more than 3, it is termed a column.
How do you calculate unsupported length?
When ratio of effective length of column and least lateral dimension of column is in between 12 to 60 then column is known as?
If the ratio of the effective length of the column to its least lateral dimension is greater than 12 then it is called a long column. The effective length to least radius of gyration ratio is less than or equal to 40. The effective length to least radius of gyration ratio is greater than 40.
What is the least lateral dimension in art?
In reality the least lateral dimension is 2D. E.g circle, square solid or filled etc. A line literaly mean it has lenght but neither bredth nor height disqualifying it. But we give it a pen/pencil size height to give it visibility when really what we are drawing is Just a long rectangle.
What is the minimum diameter of longitudinal reinforcement in a column?
The main longitudinal reinforcement bars used in the column shall not be less than 12 mm in diameter. A reinforced concrete column having helical reinforcement shall have at least six-bar of longitudinal reinforcement within the helical reinforcement.
What is the minimum number of longitudinal bars in a column?
Four and six are the minimum number of longitudinal bars in rectangular and circular columns, respectively. The diameter of the longitudinal bars should be at least 12 mm.
What is the pitch of lateral ties?
The diameter of the lateral ties shall be not less than one-fourth of the diameter of the largest longitudinal bar and in no case less than 6 mm. Hence, the pitch of lateral ties shall be kept as 300 mm. As per IS 456: 2000, clause 26.5.3.1,
