10 Questions
What is a major advantage of using beams with corrugated web over traditional rolled and welded profiles?
Higher coefficient of utilization of material
Why did the location of folds in the webs of plate girders cause welding of stiffeners in every place of concentrated load occurrence?
To avoid buckling under concentrated loads
How did the automation of production in the 80s and 90s enable the widespread use of plate girders with corrugated web?
Improved the technology of welding
What formula is used to calculate the reduced modulus of shear in Timoshenko beams?
Gred = Gf * A
In the context of plate girders, what does the reduced coefficient of shear (kred) estimate?
The change in elasticity coefficient of shear
For analyzing wavy web influence on displacements, what equation is used to calculate the resistance of the web?
VR = 0.58 * c * hw * tw * fy
What is the main advantage of plate girders with corrugated web compared to plate girders with flat webs and trusses?
Reduced material by about 20%
In the context of beam production with a sinusoidal wave web, what is the chord length of the produced web?
77.5 mm
What is the function of the station of welding (7) in the production process of girders with a corrugated web?
Joining the metal plates together
How does the presence of a corrugated web influence the overall stiffness of plate girders?
Increases flexibility at the expense of stiffness
Learn about the introduction of using corrugated iron as the web of plate girders. Understand how the folds in metal plates perpendicular to flanges act as stiffeners for the web, enhancing critical stresses and enabling the use of webs on slender sides.
