Jan 14, 2024 · To calculate the UDL line load that you can apply on 1 of the beams, we multiply the area load with half of the distance of the 2 beams. 2 k N m 2 ⋅ 5 m 2 = 5 k N m. Now, to get the point loads which act on the columns, we calculate the reaction forces of the simply supported beams. 👇👇. Reaction forces A v, A h and B v are the loads on ...
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.
Testing of many reinforced concrete beams has shown that the average stress within the compressive zone is 0.85β 1 fc ', and the resultant location is β 1 c /2 from the face of the concrete beam, as shown in Figure 5.23a. The coefficient β 1 ranges from 0.85 for fc ' ≤ 4000 psi, to 0.65 for fc ' ≥ 8000 psi (Figure 5.24).
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.
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.
Compaction affects the strength of concrete in two main ways: Increased density: Compaction helps to increase the density of the concrete by removing air voids and filling in the spaces between the particles of aggregate. This, in turn, helps to increase the strength of the concrete by improving its load-carrying capacity and reducing the risk ...

E c is the concrete elastic modulus, psi f t ' is the tensile strength of the concrete = 7.5 sqrt(f'c), psi d is the slab thickness, inches . The above equation assumes that the load acting on the slab is unique and no other nearby loads are affecting the calculation.
