The formula has been calibrated to take into consideration the particular effects of the concrete cover and the additional amplification appearing for the high values of the slenderness ratio. The third step is the development of a nonlinear amplification term for eccentrical loads. The second step is the determination of the buckling coefficient for centrically loaded columns. The first step consists of determining the plastic crushing load of the column at elevated temperature on the basis of numerical simulations. The design formula has been obtained in three steps.
#CONCRETE COLUMN CAPACITY CALCULATOR CODE#
A computer code SAFIR, developed at the University of Liège for the simulation of the structural behavior under fire conditions, has been used for the analysis of the experimental results and for the progressive development of the formulation. A large number of experimental results have been examined they have been performed at the Universities of Ghent and Liège in Belgium, at the Technical University of Braunschweig, and at the Fire Research Station in Ottawa, Canada. However, more scientific approaches such as analytical formulations should be proposed to consulting engineers for a quick and efficient design.
#CONCRETE COLUMN CAPACITY CALCULATOR HOW TO#
I hope now you understood how to calculate the load on column, beam, wall and slab.The determination of the fire resistance of concrete columns is essentially based on tabulated data containing the dimensions of the cross section and values of the concrete cover. The factor of safety is 1.5 as Per IS 456:2000, It is essential when the Load Calculation of the Column is done. Lastly, after calculating the entire load on a column, don’t forget to add the factor of safety, which is most vital for any building’s structure design for its safe and suitable performance during its service life. Calculation Of Dead Loadįor calculating the dead load of the building, we have to determine the volume of each member like footing, column, beam, slab and wall and multiplied by the unit weight of the material from which it is made.īy adding the dead load of all structural components, we can determine the total dead load of the building. The value of live load varies according to the type of building for which we have to follow the code IS 875 -1987 part 2. Usually, we consider the value of the live load for residential buildings as 3 KN/m2. Calculation Of Live loadįor calculating the live load of the building, we have to follow the permissible load values as per IS- 875 1987 part 2. Live load is one of the important loads in design consideration. These loads keep on varying from time to time. Impose or live loads are the dynamic loads due to the use or occupancy of the building including, furniture. These loads may tension or compression loads. Load Calculation of the Buildingīuilding load is the sum of dead load, Imposed or live load, wind load, earthquake load, snow load if the structure is located in a snowfall area.ĭead loads are static loads due to the structure’s self-weight that remains the same throughout the building’s lifespan.
Hence, we can evaluate the slab load will be about 6 to 7 kN (approx) per square meter from the above calculation. If we consider the superimposed live load is about 2 kN per meter, and the Finishing load is about 1 kN per meter. Therefore, the Self-weight of slab per square meter will be Let us consider the slab thickness of 100 mm.
It carries typically uniformly distributed gravity loads acting to its surface and transfer it to the support by shear, flexure, and torsion. The slab may be supported by masonry walls, by RCC Beam, or directly by column. It is the plane element which depth is much smaller than its width and span. What is the slab?Ī slab is an extensively used structural component that forms the floors and roofs of the buildings. In a building, a wall helps to form a fundamental part of the superstructure and helps to divide interior space and gives privacy, soundproofing and fire protection also. The inner wall is also known as the partition wall. While the inner wall divides the enclosed area to provide rooms of the required size. The outer wall helps to provide an enclosure to the building. In a building mainly there are two types of walls that are the outer wall and inner walls. Usually, it is constructed with bricks and stones. It is a continuous vertical structure that divides or encloses the space of an area or building along with provides shelter and security.
