👉DO YOU KNOW ?
.
▶️Do you know that a doubly reinforced column base gives more rigidity, stability and the ability to transmit and distribute the load effectively to the soil beneath. The secondary reinforcement base provides resistance to punching stress as a result of an imposed load. Good morning peoples.
.
▶️Do you know that a weak footing of a structure can be strengthened through a means know as jacketing. However, the new footing base helps to establish a better platform for the effective distribution of imposed load substructurally without any form of deformation.

👉SHORT COLUMN VS LONG COLUMN
.
▶️SHORT COLUMN: Short column is defined as the column that contains very large lateral dimension with reference to its length or height is called as short column. Here, the proportion of effective length to its lateral dimension is under or equivalent to 12.
.
*The proportion of effective length of a short column to its radius of gyration remains under 40 or equivalent to 40.
.
*Bulking tendency is very poor. A column buckling analysis results in finding out the maximum load that a column can sustain prior to collapsing.
.
*The load bearing strength is high with reference to the long column of the similar cross-sectional area.
.
*The collapsing of short column occurs due to crushing.
:
▶️LONG COLUMN: Long column is defined as the column that contains small lateral dimension with reference to its length or height. Here, the proportion of effective length of column to its lowest lateral dimension surpasses 12.
.
*The proportion of effective length of a long column to its lowest radius of gyration surpasses 40.
.
*Column buckling easily occurs in long and slender column.
.
*The load bearing strength of a long column remains under with reference to short column with similar cross sectional area.
.
*The column normally collapses in buckling.

▶️I would like to start my discussion on RCC structures by stating some points on modes of failure of RCC sections.
.
*The failure modes to be discussed here are based on the amount of reinforcement present on the section.
:
*Rcc sections can fail in one of the three ways:-

1. The reinforcement yielding before the concerete reaching its maximum stain( 3.5 per thousand in EBCS-2,1995)

2. The reinforcement reaching its yielding stain and at the same time the concerete reaching its ultimate strain.

3. The concerete reaching its crushing stain before the reinforcement yields.

[The second mode of failure is called balanced failure and from this point forward it might be used as balanced failure or in terms of the amount of reinforcement as balanced reinforcement.]

*The first mode of failure, which is the most desirable in the senses that it gives ample time before complete collapse , occurs when the amount of reinforcement provided in the section is less than the balanced reinforcement.

*The second mode of failure occurs when the amount of reinforcement provided is such that the steel and the concerete reach their ultimate carrying capacity at the same time.

*The third mode of failure, which is undesirable in the sense that failure is catastrophic and immediate, is a result of reinforcing the section beyond the balanced reinforcement.

👉What are the types of column in construction?

🌟Common types of columns in construction include:

1. Concrete Columns: Made of reinforced or precast concrete, widely used for their strength and durability.

2. Steel Columns: Fabricated from steel sections or tubes, providing structural support in many buildings.

3. Wooden Columns: Typically used in residential construction, often as decorative elements.

4. Composite Columns: Combine materials like steel and concrete to optimize strength and cost-effectiveness.

5. Masonry Columns: Constructed with bricks or stones, commonly used in historical or traditional architecture.

6. Hollow Steel Sections (HSS) Columns: Tubular steel columns that offer a high strength-to-weight ratio.

7. Timber Columns: Utilized in various forms, such as solid timber or laminated timber, especially in residential and low-rise structures.

8. Braced Columns: Designed with additional bracing to enhance lateral stability, common in seismic-prone areas.

9. Prestressed Concrete Columns: Reinforced with tensioned cables to minimize cracking and increase strength.

10. Fiberglass Columns: Lightweight and corrosion-resistant, suitable for certain architectural applications.

🫵The choice of column type depends on factors like the building's design, load-bearing requirements, and environmental conditions.

👉Staircase Design Principles
.
▶️A staircase is an integral part of a building. It is a series of steps arranged in an order so that people can go from one floor of a building to another . The stair should be as per standard design principles and constructed in a such a manner that people can negotiate the steps with ease.
.
▶️Staircase
.
▶️A staircase is an integral part of a building; residence, office or public utility. It is designed and built according to the local building codes. A staircase may be straight, circular, flared or spiral. Ergonomic design principles are to be followed in the planning and construction of stairs to avoid inconvenience to the users as well as to avoid accidents.
.
▶️Staircase Design Principles
.
▶️Stairs are a series of steps arranged in an order to provide access from one floor of a building to another floor. They should be provided in a convenient location of the building. In case of a multistory building, though elevators will be there for the normal movement from one floor to another, stairs are a must for emergency exit in case of fire or other calamities.
.
▶️Technical Terms
.
👉The following are the technical terms associated with a stair.

1. Step: The portion of the stair where the foot lands during ascending/descending.

2. Tread: The horizontal portion of a step.

3. Riser: The vertical portion of a step.

4. Stringer: The inclined member which supports the steps.

5. Landing: It is the horizontal platform provided at the end of each flight.

6. Pitch: It is the slope of the stair.

7. Railing: It is the inclined member of a stair which is to support the hand.

8. while descending or ascending.

9. Baluster: It is the vertical intermediate support of the hand-rail.

▶️Characteristics of a Good Stair

👉 The following are the characteristics of a good stair.

10. It should have easy access from all sides of the building

11. It should be well ventilated

12. It should have wide landing at end of each flight

13. Normally there should not be more than 12 steps in a flight.

14. The rise and go of the steps should be so proportioned that the ascending and descending of the flight is easy.

15. Handrail must be provided at least on one side of the stair

16. The inclination of the stair should be between 30 to 45 degrees.

▶️Types of Stairs
.
👉The different types of stairs are:
.
*Straight stairs

*Quarter-turn stairs

*Dog-legged stairs

*Open-newel stairs

*Circular stairs

*Bifurcated stairs

*Geometrical stairs

*Spiral stairs

*Construction of Stairs
:
👉Stairs are constructed with any of the following materials.
.
▶️Brick masonry, Stone masonry, Timber, Steel, Reinforced Cement Concrete
.
▶️Summary of Staircase Design Principles

17. Type of Stair: The type of stair depends on the type of building, availability of space and the purpose of stair.

18. Rise and Going: The standard rise and tread is 15 x 25 cm. However the dimensions can be changed depending on the actual site conditions.

19. Number of rises: The number of rises is equal to the total height of the room divided by one rise.

20. Number of threads: This is equal to number of rises minus one.
