KaderColumn – A useful construction program for column analysis

KaderColumn is a powerful construction program that is created for reinforced concrete tied short columns.

It can be used to create the designs of columns based on up to eleven cases of loading comprising of axial load and bending moment implemented about the maximum principle axis.

The program allows to build up the column strength interaction diagram (Bending moment-Axial load curve) out of the input data of the cross-section and verify whether all input cases of loading are situated inside the design curve. If the input data of the cross-section is insufficient, the program enhances them to commence from the Min. Roh to the cross-sectional dimensions unless all input cases of loading remain inside the design curve. The program provides proposition for setting ties properly and draws them.

Features:

  • It is very user-friendly and short.
    • It computes and draws the column strength interaction diagram toward a reinforced concrete tied short column having a rectangular (containing rebars at two sides only or at all four sides), square or circular section and depending on axial load and bending moment around the max. principle axis of its cross-section.

 

  • Up to eleven cases of loads (axial load and bending moment) are permissible. The program examines all these cases which should remain inside the column interaction diagram.
    • It designs the section and draws by organizing ties in an efficient manner.
    • The user will be capable of rectifying the section dimensions, the min. and max. ratio of reinforcement and some other parameters for obtaining the rational section from his point of view.
  • The user will be able to save and open the input data file that is already saved by the program.
    • The program employs the ultimate strength method for design and abides by the exact ACI 318-02 Code requirements.

How to determine grades of concrete following IS 456:2000 standard

This construction video tutorial explains the grades of concrete with adherence to IS 456:2000 as well as process for detecting the characteristics strength of concrete.

IS 456-2000 refers to an Indian standard code of practice for general structural use of plain and reinforced concrete.

Grade of concrete determines the compressive strength of concrete. To calculate grade of concrete, standard compression test is carried out on concrete cube of 150 mm. Grade of concrete is demonstrated with M10, M20, M30 etc. where M stands for Mix i.e. mix of constituents used for concrete. Numeric figure in M stands for characteristics compressive strength (fck) that is stated MPa (N/mm2).

Characteristics compressive strength means the strength of material under which not over 5% result is presumed to fall.

As for example if 20 samples of concrete cubes are casted and carried out compression tests for them in the laboratory to determine their compressive strength. Results for test are 27.3, 25.4, 26.9, 25.1, 23.8, 27.6……20 results. If these are organized in increasing order, here 23.8 is less than 25 and remaining are greater than 25 in MPa. So, it signifies that one result falls under 25 MPa and it is detected that only 5% of results fall under 25. Therefore, grade of concrete remains M25.

As per IS code, there are three comprehensive categories for concrete as follow :-

Type of concrete Grade
High Strength Concrete Over M 60
Standard Strength Concrete M25 to M55
Normal Strength Concrete M10 to M20

 For online demonstration, watch the following video.

In this construction video tutorial, one will be familiar with how to determine maximum bearing capacity of various types of soil.

Safe Bearing Capacity of Soils is defined as the maximum strength of loading that the soil will bear securely devoid of the risk associated with shear failure.
The bearing capacity of soil refers to the maximum average contact pressure among the foundation and the soil which should not lead to shear failure in the soil.

In the jobsite you will be provided with drawings along with soil investigation report. From soil investigation report, you can get various information about the soil upon which the building will be constructed like number of fillings in the soil, the bearing capacity of soil, bearing pressure of soil to undergo.

There may be some errors in the report or higher value for bearing capacity.

In this video, you will learn how to find out maximum bearing capacity of soil and tally this figure with the soil test report to check for any discrepancy.

In the video, there are two heads like soil type and safe bearing capacity of soil. In soil type, there are different types of soil like combination of soft, wet and muddy clay, fine/loose or dry sand, soft clay, black cotton soil, moist or sand clay mix, loose gravels, compacted gravels, soft rock, sand or lime stone, hard rock/granite/trap etc. For each type of soil, the maximum safe bearing capacity is provided.

Learn to compute cement quota, brickwork volume & no. of fixes for a brick wall

This construction video tutorial will show the details of cement quota, brick work volume, number of fixes for a brick wall construction.

To calculate the brickwork volume, just apply the following formula :-

Total brickwork area x wall thickness
= 31.98 x 0.2 = 6.38 m3

The ratio of cement & mortar needed in brickwork is 1:3 (it can also be taken as 1:5 and 1:6).
Volume of brickwork = 6.38 m3
For 1 cubic meter of cement mortar, the volume of sand will be 0.2m3
For 6.38 cubic meter, the volume of sand will be 6.38 x 0.2 = 1.276 m3

For 1m3 cement mortar, the volume of cement will be = (0.2×1440)/3 (3 denotes last digit of ratio)
= (0.2 x 1440)/3 = 96 KGS
For 6.38 cubic meter, the volume of cement will be 6.38 x 96 = 612.48 KGS

To work out the number of cement bags, just divide it by 50 (as weight of 1 cement bag is similar to 50 Kg)
Therefore, 612.48/50 = 12.24 bags = 13 bags (approx.)

Some useful guidelines on Vastu for a Living Room

The Vastu for Living Room provides a series of fundamental rules and if these rules are pursued properly, you along with your family can live problem free life in the Living Room. It is very crucial to keep the face of the living room to the East or the North direction. It is recommended to keep the face of your living room to the North as it will bring more prosperity. Toward North faced room, remember that the room should be larger in size with regard to the rest rooms of your house facing other directions but the height of the room should be little short.

In Living Room Vastu Shastra, the drawings, patterns and designs are dependent on the arrangements with the directions known as North, South, East and West. Living Room Vastu Shastra is mostly utilized over the ages on Hindu architecture and also in other arenas like vehicles, furniture, sculpture, paintings, so on.

Living Room Vastu placement: Beside maintaining face of the room to the proper direction, Vastu for living room also suggests to keep the slope of its flooring towards the North or the East. Regarding the doors, the eastern and the western doors are treated very sacred for your living room. The decorative items which are situated inside, particularly the heavy materials like the show case and all, should be arranged in the West or the South direction.

Vastu for living room also describes that the sitting position of the head of the family should have been in the North or the East. It is recommended not to arrange the television set to the North-east or the South-west rather it’s face should be directed to South-east. The telephone set should be kept either in the North or the East or the South-East direction. It is also suggested that the statues or portraits of Gods and goddesses should be arranged in the North-east corner. If any stuff of animal hide or skin is arranged on the walls, it should be hanging on the North-west walls.

Colors on Wall as per Vastu: Vastu for living room also reveals a vital factor about the color of the walls. Try to circumvent employing red or black for the walls. Painting on it should be done with colors like blue, yellow, white or green. Arrange the fanciful chandelier slightly to the West side of the room and it shouldn’t be positioned at the center. The shape of the furniture should be as much as possible square or rectangle and not circular, oval, hexagonal or shaped like an egg.

Shear Force and Bending Moment Of Simply Supported Beam With Point Load

The Civil Engineers should contain clear and concise ideas on shear force and bending moment to make perfect analysis of any structure as well as design of any structural member.

In this regard, Parag Pal, the famous B.E. Civil Engineer, has presented a useful video that focuses on shear force and bending moment of simply supported beam with point load to find out the sfd and bmd of any point load member.

In engineering term, a point load refers to an established load (force) that is situated with a single, specific point on a supporting structure or structural member.

In construction, a point load is set aside only for lighter structures or other cases where the load or force is comparatively light and not cause to undergo unnecessary stresses. To sustain structural reliability, designs and blueprints are properly planned to prevent the application of point loads in other situations.

If Point loads are not predicted, they can result in collapsing of structures.
