How to use kani’s method for making analysis of continuous beam

In this construction video tutorial, the renowned civil engineer, Mr. Parag Pal, has briefly explained how kanis method is used to continuous beam that contains fixed ends, to evaluate the beam and obtain the final moments.

The continuous beam comprises of the point load and the UDL load.

This method was developed by Dr. Gasper Kani of Germany in 1947.

The method provides a iterative scheme for employing slope deflection method. It is mostly recognized for frame analysis.

It comprises allotting the unidentified fixed end moments of structural members to adjoining joints, with the purpose of meeting the conditions of continuity of slopes and displacements.

Benefits:

1. Kani’s method circulates the total joint moment at any phase of iteration.

2. The more crucial feature of Kani’s method is that it is self reformative. If any fault occurs at any phase of iteration, amendment is made in consequent steps.

Framed structures are seldom symmetric and dependent on side sway, therefore Kani’s method is considered as greatest and much easier as compared to other methods like moment distribution method and slope displacement method.

To get more information on kani’s method, go through the following video tutorial.

How to create rate analysis of civil works

Each construction project is segregated into various numbers of activities. Each activity is supported with types of civil or construction works.

As for instance, when a building is constructed there are various activities like excavation or earthwork, concrete work, masonry work, wood work such as doors and windows, plumbing, flooring, waterproofing, finishing work like plastering, painting and distempering.

The Activity earthwork is segregated into different types depending on depth and type of soil. As for instance, an excavation of 1.5m deep in soft soil, an excavation of 3m deep in hard soil. Similarly, concrete work is segregated into several types on the basis of its mix proportions and its placement.

As for instance, M25 reinforced concrete is suitable in foundation, M30 reinforced concrete work in columns, slabs etc. Similarly, there are various small civil works in each construction project.

The construction project cost is estimated on the basis of each works related to each construction activity. Thus it is necessary to compute the cost of each small works.

Rate analysis of Civil Works or Building Works is the determination of cost of each construction work per unit quantity.

This cost includes the cost of materials, labors, machinery, contractors profit and other diverse insignificant expenses essential for the specific work that should be executed in unit quantity.

As for instance, cost of 1 cubic meter of M20 RCC work in slab, Cost of 1 cubic meter of excavation in soft soil of 1.5m depth, cost of 1 square meter of plastering of 20mm, cost of 1 square meter of painting work with specified paint in 2 layers or 3 layers as necessary.

Compute the cost of materials in rate analysis as composite of cost of material at origin, its transportation costs, taxes. The rate of labor is set with skill of the labor, like skilled labor, semi-skilled and unskilled labor. The cost of materials and labors differ from place to place. Thus, the cost of each construction work fluctuates from place to place.
