How to design a beam in excel with coefficient method

This construction video tutorial sifts through the process for evaluating engineering drawing easily.
This construction video tutorial provides detailed guidelines on how to use excel based spreadsheet to design a beam. Here coefficient method is applied for designing purpose.
The calculation is made on the basis of the following drawings :-
a. Typical floor plan
b. Ground floor plan
c. Column Layout
d. Beam Column Layout
The coefficient method refers to a rapid hand-system that can be used for computing the moments in two-way slabs supported with edge beams. This method was initially contained in the 1963 edition of the ACI code as a method for creating design of two-way slabs which are supported on all four sides through walls, steel beams, or deep beams. The most recent version of the ACI code 318 does not contain the coefficient method but you can apply it for two slab systems with edge beams.
This method employs tables of moment coefficients for different types of slab edge conditions. The coefficients are dependent on elastic analysis but also comprises of considerations for inelastic moment redistribution.

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.

Some useful tips to read civil engineering drawings efficiently

This construction video tutorial sifts through the process for evaluating engineering drawing easily.

In this video, some crucial topics like grid lines in civil engineering, problems found in the drawing, are explained briefly.

A civil drawing contains a series of various types of site drawings. It is a type of technical drawing that provides information on utility, grading and drainage, site improvements, and landscaping plans as well as other site details. The objective of these drawings is to provide a clear conception of all things in a construction site to a civil engineer. In these drawings the site layout plan and floor plans are set up.
Civil drafters arrange the drawings, topographical and relief maps which are applied in leading construction or civil engineering projects like highways, bridges, pipelines, flood control projects, and water and sewage systems.
In the drawing, there are Grid Lines specified with dimensions n. The grid lines facilitate references to be created on the basis of the position/location of different constituents in the project. The Main Contractor will then employ a license surveyor to organize the grid lines on site.
In the video, a sample drawing is considered. There are 8 columns in this drawing with the dimension 29.5” x 19.5”. Here the header lines will demonstrate the center line of the column.

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
