Bookmark or Share- structural engineering - stiffness factor for member in beam ...The far end formula, $\frac{3EI}{L}$, applies if the beam is discontinuous in that point. This means that the point of reference is the end of the beam where the support is a hinge/pin.
- Difference between Stiffness (K) and Modulus of Elasticity (E)?Stiffness (F=Kx) is the extent to which an object resists deformation in response to an applied force. Elastic Modulus (E=Stress/Strain) is a quantity that measures an object or substance's resistance to being deformed elastically when a stress is applied to it.
- What's the difference between ductility and stiffness?Stiffness, at least when talking about the material (without introducing the geometry of the object) is I think synonymous with elastic modulus, i.e. the slope of the elastic portion of the curve. We also use stiffness when talking about objects, for instance stiffness of a spring, or stiffness of a truss.
- How does stiffness/rigidity affect the bending moment of a beamIn simplified terms, this is because in statically determinate structures one can determine how the load is transferred through the structure to the supports without caring about the stiffness itself. In indeterminate structures, however, the stiffness directly impacts how the load is shared by the supports.
- How does width and thickness affect the stiffness of steel plate?Use one of the many, free, online moment of inertia calculators (like this one) to see how increasing the height of the beam will have an exponential effect on increasing the stiffness of the beam. And this site helps provide a pictorial view of the load(s) upon a beam depending upon differing configurations, such as where the supports are and ...
