In the field of engineering, a point load is a load applied to a single, specific point on a structural member. It is also known as a concentrated load, and an example of it would be a hammer hitting a single nail into a beam. The alternative to a point load is a distributed load.


The specified live loads are generally expressed either as uniformly distributed area loads or point loads applied over small areas. The uniformly distributed loads are applied to portions of the structure that is likely to see a fairly uniform distribution of items over large areas (areas the size of a single room or larger).


The reason for the disparity between factors for dead load and live load, and thus the reason the loads are initially categorized as dead or live is because while it is not unreasonable to expect a large number of people ascending the staircase at once, it is less likely that the structure will experience much change in its permanent load.


Your point load is then equal to wl/2 as noted above assuming w is taken as the average roof load per foot. All my numbers are correct for this case. RE: Distributed Load vs. Point Load UcfSE (Structural) 26 Jan 07 20:07. csd72, I was not addressing you and I do not need to review your "maths". My post was directed to the OP who asked a general ...


The acceptable live load will vary considerably based on the occupancy and expected use of a structure or structural element. For example, the live load for a room in a single family residence will be significantly smaller than the live load for an area of equal size at a movie theatre or sporting event. How live load codes work


Distribution of Concentrated Load. The concentrated loads may be distributed over a small area. For example, consider a floor joist that has a constant tributary width of 4 ft in an area that has office occupancy. The uniform distributed live load and the concentrated load from ASCE 7-05 Table 4-1 are 50 psf and 2000 lbs, respectively.


Write your answer as the total load in Step 3 applied to the point you determined in Step 2. For the rectangle, the point load is 240 kN applied to a point 3 meters from an end in the length dimension and 2 meters from an end in the width dimension. For the beam, the point load is 50 kN applied to a point 2.5 meters from either end.


QUESTION: Is it possible to apply live load as point load in Conspan? ANSWER: Currently it is not possible to apply the Live load as point load . The workaround solution is apply the Live Load as Dead load on the beam and then change the Distribution factors and Load factors to mimic the Dead load as Live load.


What is the difference between superimposed dead load and dead load in ETABS? Update Cancel. ... hence I would touch upon a point not yet mentioned. ... Is a load combination made up of a live load, dead load, wind load, and earthquake load, possible?


There are three types of load. These are; Point load that is also called as concentrated load. Distributed load; Coupled load; Point Load. Point load is that load which acts over a small distance.Because of concentration over small distance this load can may be considered as acting on a point.Point load is denoted by P and symbol of point load is arrow heading downward (↓).
