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.

What are the maximum bearing capacity of various types of soil

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.

Go through the following video tutorial, to get more details.
