Refers to **loads that do, or can, change over time**, such as people walking around a building (occupancy) or movable objects such as furniture. Live loads are variable as they depend on usage and capacity.

Definition of live load

: the load to which a structure is subjected in addition to its own weight.

U.S. building codes specify a uniform live load of 40 pounds per square foot (psf) for most residential floor designs. This load is intended to account for the large number of loads that can occur in a residence.

Live loads (also known as applied or imposed loads, or variable actions) may vary over time and often result from the occupancy of a structure. Typical live loads may include; people, the action of wind on an elevation, furniture, vehicles, the weight of the books in a library and so on.

The dead loads are permanent loads which result from the weight of the structure itself or from other permanent attachments, for example, drywall, roof sheathing and weight of the truss. Live loads are temporary loads; they are applied to the structure on and off over the life of the structure.

IBC Section 1607 specifies the prescribed minimum live loads based upon occupancy. For an office building, the minimum uniform live load is 50 psf over the entire floor area plus a concentrated load check of 2000 pounds over any 2'-6” x 2'-6” square space.

LIVE LOADS (ROOF). Those loads produced (1) during maintenance by workers, equipment and materials; and (2) during the life of the structure by movable objects such as planters and by people.

Different types of loads in buildings and structures

- Different types of loads. The loads in buildings and structures can be classified as vertical loads, horizontal loads and longitudinal loads. ...

- Live load. ...
- Wind load. ...
- Snow load. ...
- Earthquake load. ...
- Load combination. ...
- Special loads.

These limits are based on live loads and activities experienced in specific rooms of a house. Examples of code-prescribed deflection limits and live load values are: Living room floors L/360 & 40 psf. Bedrooms and habitable attic floors L/360 & 30 psf.

Generally, the customary floor dead load is 10-12 PSF (pounds per square foot) for floors, 12-15 PSF for roof rafters and 20 PSF for roof trusses. However, these may increase when a heavy finish material, such as brick veneer walls or tile floors/roofs, is specified.

Floor load capacity is the total maximum weight a floor is engineered to support over a given area. In the U.S. it is expressed as pounds per square foot. Floors are engineered to carry a maximum static load and a maximum dynamic load that can't be exceeded without the risk of compromise to the structure. Examples.

Live load refers to when a truck driver reaches a pickup location, then laborers arrive and load or unload the cargo. It consumes a considerable amount of time as the driver has to wait while the goods are loaded or unloaded. Depending on the goods, the loading and unloading time may take 40 minutes to 3 or 4 hours.

A live load happens when a truck delivers a container and waits for it to be fully loaded or unloaded, before bringing the same container out.

Live loads are those loads produced by the use and occupancy of a building or structure and do not include construction loads, environmental loads (such as wind loads, snow loads, rain loads, earthquake loads and flood loads) or dead loads (see the definition of “Live Load” in IBC 202).

Reduction in roof live loads is allowed per the 2012 International Building Code (IBC), section 1607.12. 2 for ordinary flat, pitched and curved roofs, and awnings and canopies other than of fabric construction supported by a skeleton structure.

There are two types of loads in construction: live loads and dead loads. Ever-changing live loads like snow and ice are temporary weights on the structure. Dead loads are all the permanent parts of the building that add to the weight of the structure.

This downward imposed load on the home is also known as the snow load. The North Zone design live load equates to 40 pounds per square foot, the Middle Zone equates to 30 pounds per square foot, and the South Zone equates to 20 pounds per square foot.

For a residential deck, the code requires it be designed to support a minimum 40-psf live load. The live load is the external force applied to a deck due to the activities of its use. People, furniture and any other movable, physical objects on the deck are covered under live load.

Slab Load Calculation = 0.150 x 1 x 2400 = 360 kg which is equivalent to 3.53 kN. Now, If we consider the Floor Finishing load to be 1 kN per meter, superimposed live load to be 2 kN per meter, and Wind Load as per Is 875 Near about 2 kN per meter.

Dead loads are static forces that are relatively constant for an extended time; usually the weight of materials plus immovable fixtures such as carpet, roof and etc. Minimum design dead load can be found in ASCE 7 Table C3-1.

Step 1 – Find out the no. Of bars and their dimensions in one meter span of slab in shorter direction. Step 2 – Find out the grade of concrete. Step 3 – Using the IS 456 page 90 formula, calculate the area of steel present in tension and the thickness of slab and thereafter find the moment of resistance of slab.

Dead load = volume of member x unit weight of materials

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.

The weight of the formwork plus the concrete is considered dead load while the live load is made up of the weight of workers, equipment, material storage and other like items which is supported by the formwork.
