Jan 14, 2024 · A UDL is a load that is evenly distributed over a given area or length. In engineering, it’s often used to describe the self-weight of a structure, such as a beam or slab. UDL’s often are represented as a force per unit length or area, such as kips per foot (kip/ft) or kilonewton per square meter (kN/m 2). # UDL.
Most real-world loads are distributed, including the weight of building materials and the force of wind, water, or earth pushing on a surface. Pressure, load, weight density and stress are all names commonly used for distributed loads. Distributed load is a force per unit length or force per unit area depicted with a series of force vectors ...
3.3.1 Intensity. Distributed loads are a way to represent a force over a certain distance. Sometimes called intensity, given the variable: Intensity w = F / d [=] N/m, lb/ft. While pressure is force over area (for 3d problems), intensity is force over distance (for 2d problems). It’s like a bunch of mattresses on the back of a truck.
of the edge-to-edge width of bridge and 18,000 mm in the case of single-lane loading, and 18,000 mm in the case of multilane loading, and N L is the numbr of design lanes. 6.3.5 Load Distribution for Substructure Design Bridge substructure includes bent caps, columns, pier walls, pile caps, spread footings, caissons, ° ° S ° ° ° ° ° ° ().
C load factor of 1.25 for all spans. To check possible uplift of the bearing, place the live load in the second span and use the minimum. DC load factor of 0.90 for all spans.Superstructure design uses the maximum permanent-load load factors almost exclusively, with the most common exception being u.
Find the equivalent point force and its point of application for the distributed load shown. Answer. Solution 1. The equivalent load is the ‘area’ under the triangular load intensity curve and it acts straight down at the centroid of the triangle. This triangular loading has a base and a 10 lb height so. Solution 2.

Uniform intensity. A distributed load with a constant intensity over an area is said to have a uniform intensity. Accordingly, a uniform load or a uniformly distributed load conveys the same meaning. With an analogy to the weight load of a box on a surface, the magnitude of total (resultant) force exerted by a uniform load over an area is .
