# How to do load calculations

To calculate that number, divide the VA rating of the circuit by VA for each receptacle strap. Fig. 3. The minimum load for each commercial general-use receptacle outlet is VA per strap. In this example, the 15A, V breaker could accommodate 1,VA of load (V x 15A = 1,VA). Mar 23,  · The load / running meter to be equal to m (6 inch) x 1 x x = kg, which is equivalent to kN/meter. (1 kilogram is equal to kilonewtons) Beam Load Calculation. Step 1. mm x mm excluding slab. Step 2. Volume of Concrete = x x 1 = m?; Step 3. Weight of Concrete = x = kg; Step 4.

The lload of the residential samsung c6712 star ii duos whatsapp free download load calculation is to accurately determine the size of the electrical service base upon the electrical equipment that will be installed. The national electrical codes are the basis of making sure the electrical service is sized properly and installed correctly.

The General Electrical Load Requirements are based on the inside square feet area of the home which is then used to calculate the basic lighting load and required appliance circuits. Click on the Question Mark Buttons for more specific information relating to each section and entry.

Appliances and Motor Type Loads are typically larger equipment used in the kitchen, laundry room, garage. Be sure to check the nameplate information for accurate calculations. Heating and Air Conditioning. Properly Identifying Heating and Air Conditioning Equipment is very important because the equipment typically requires a larger electrical load.

VA is the abbreviation for volt-ampere, which is a unit of power that is determined by multiplying the voltage and the amperage current in a circuit. VA is a standard measurement of electrical power that is used for identifying electrical circuit component ho. A watt is a measure of true power which is required to perform work at the rate of 1 joule per second.

The wattage is calculated by multiplying voltage times the power factor hwo the circuit. PF or Power Factor is the ratio of the actual power in watts to the apparent power in volt-amperes which is expressed as a percentage. The load calculator is divided into three main sections which enable you to enter the necessary information about the home project and the proposed electrical equipment that will be installed.

Electrical Apprenticeship 1 ». Recent Testimonials I think your site offers the the clearest and best electrical information for homeowners I have ever seen on the net. You have given me confidence to do my own projects which I never had before. Paul, from Foxboro, Massachusetts I wish I found this site earlier, it is by far the best electrical related resource I have found on the web. George, from How to do load calculations, Pennsylvania I love this site for an office worker that does not know anything about electric wiring.

Collin, from Grand Rapids, Michigan Thank you for answering my question. I was able to get this done. This site is perfect. I am glad I found it. Please keep it going.

The Residential Electrical Load Calculator is Pre-Loaded with electrical information for you to chose from. Click on the Question Mark Buttons for more specific information relating to each section and entry. Step 2. Appliances and Motor Type Loads are typically . Mar 24,  · (A load calculation determines the size of a building’s heating load on one of the coldest nights of the year and the size of a building’s cooling load on one of the hottest afternoons of the year.) It’s important to know the size of these loads to determine the size of . May 21,  · AC capacity = CFA ? sf/ton. CFA is conditioned floor area in square feet. Sometimes the rule is sf/ton, sometimes sf/ton. But it’s always right in that neighborhood. So if you get a load calculation report, find the total cooling load (sensible plus latent) and divide it .

A compression member, i. These are used to transfer a load of superstructure to the foundation safely. Mainly columns , struts, and pedestals are used as compression members in buildings, bridges, supporting systems of tanks, factories, and many more such structures.

A column is defined as a vertical compression member who is mainly subjected to the effective length and axial loads of which exceeds three times its least lateral dimension. The compression member whose effective length is less than three times its least lateral dimension is called Pedestal.

The compression member who is inclined or horizontal and is subjected to axial loads is called Strut. Struts are used in trusses. The function of columns is to transfer the load of the structure vertically downwards to transfer it to a foundation. Apart from the wall performs the following functions also:.

The beam is a structural element that stands against the bending. Mainly beam carries vertical gravitational forces, but also pull the horizontal loads on it. The beam is called a wall plate or sill plate that carries the transmits and load it to the girders, columns , or walls. It is attached with. In the early centuries, timbers were the most preferred material to be used as a beam for this structural support purpose, now to bear the force along with carrying vertical gravitational force, now they are made up of aluminum, steel, or other such materials.

In actual means, beams are these structural materials, which bear the sheer force of the load and the bending moment. To carry on the more tension and load, pre-stressed concrete beams are widely used nowadays in the foundation of bridges and other such humongous structures.

Wall is a structural element that divides the space room into two spaces rooms and also provides safety and shelter. Generally, the wall is differentiated as two types of outer-wall and inner-wall. Outer-walls give an enclosure to the house for shelter, and inner-walls help to partition the enclosure into the required number of rooms.

Inner walls are also called as Partition walls. Walls are built to partition the living area into different parts. They impart privacy and protection against temperature, rain, and theft. A slab is constructed to provide flat surfaces, typically horizontal, in building roofs , floors, bridges, and other types of structures.

The slab could be supported by walls, by reinforced concrete beams normally cast monolithically with the slab, by structural steel beams, either by columns or from the ground. A slab is a plate element having a depth D , very small as compared to its length and width.

A slab is used as floor or roof in buildings, carry distribution load uniformly. Besides this above loading, the columns are also subjected to bending moments that have to be considered in the final design. These tools are reduced laborious and consuming method of manual calculations for structural design, this is highly recommended nowadays in the field. Note: 1 Kilonewton Is Equal to While doing calculations, we assume the self weight of columns is between 10 to 12 kN per floor.

For a 9 inch mm thick Brick wall of 2. This method can be adopted for load calculations of Brick per running meter for any brick type using this technique. For aerated concrete blocks and auto-claved concrete ACC blocks, like Aerocon or Siporex, the weight per cubic meter is between to kg per cubic meter. So, from the above data, we can estimate the slab load to be around 8 to 9 kN per square meter.

It is a vertical compression member subjected to direct axial load and its effective length is three times larger than its least lateral dimension.

By calculating the volume of each member and multiplying by the unit weight of the materials from which it is composed, an accurate dead load can be determined for each component. Hey, I am Krunal Rajput. The Man Behind CivilJungle. I started this site to spread knowledge about Civil Engineering. I am a Degree Holder in Civil Engineering. I was totally difficult to understand from the reinforcement requirements.
