Concrete beam

A structural member of reinforced concrete placed horizontally to carry loads over openings. Because both bending and shear in such beams induce tensile stresses, steel reinforcing tremendously increases beam strength. Usually, beams are designed under the assumption that tensile stresses have cracked the concrete and the steel reinforcing is carrying all the tension. See Stress and strain

It could be seen from the figure that pre-stressed concrete beam mainly showed bending modes.
An analytical procedure was then proposed using the so-established formula and based upon the strain compatibility condition to predict the low-cycle flexural fatigue behavior of the concrete beam reinforced with the steel rebar or hybrid FRP-steel bar.
Thanks to his safety first attitude, no-one was injured when the 50-foot jib of a mobile crane collapsed when moving a 42-foot, 21/4-ton concrete beam, above.
Domestic and foreign researchers [9-18] adopted various finite element software to simulate CFRP reinforced prestressed concrete beam, BFRP reinforced concrete beam, and GFRP reinforced concrete beam and to simulate the variation trends such as load, deflection, crack, and bond slip, so as to make comparative analysis with the test results and obtain relevant difference conclusions.
Similarly, shear design of a reinforced concrete beam is quite straightforward.
Five cars were crushed by the collapsed 180-ton concrete beam lifter but no casualties were reported so far.
To test the reliability of FCEM results for dynamic analysis of continuous structures in the elastic domain, a simply supported concrete beam was constructed and tested in the laboratories of the Civil Engineering Department (DEC-ISE) of the University of Algarve, Portugal.
ABAQUS offers a variety of elements; the literature [12], using the "Euler-Bernoulli" beam elements and "Timoshenko" beam elements to simulate concrete beam and using keyword Rebar to simulate the nonprestressed steel, but using beam element to simulate the prestressed concrete beam, is an approximate simulation method; there are still shortcomings.
Failure of the plain concrete beam without stirrups (V-0-0) was characteristic of a shear failure by compression strut; i.e., a single diagonal crack was formed in the web that spread to the upper beam.
This undergraduate textbook introduces the structural design of concrete beam sections, slabs, columns, walls, and foundations for single-story houses, medium-rise buildings, and tall multi-story buildings.
Bangkok: At least 11 workers died and 18 others were injured when a large concrete beam collapsed Tuesday at a construction site just outside Bangkok, police said.
BANGKOK (CyHAN)- A concrete beam of a hospital building under construction in central Thailand's Samut Prakan province collapsed on Tuesday, leaving at least 11 killed and 17 others injured, local media reported.
