BC is only a segment of the beam ABCD. The "far end" of BC from B is D.fonseh said:
That's my understanding. But please bear in mind that my entire knowledge of the subject comes from the textbook extracts you have posted.fonseh said:
May I know which part ? Can you highlighted it ?haruspex said:
I have not noticed an actual definition of "far end" but just thinking about how I would expect a beam to behave it is clear that if any part of a beam is unable to rotate at all it will make the beam stiffer at all joints. Hence that is how I interpret the term.fonseh said:
The stiffness factor for a member in a beam is a measure of its resistance to deformation under an applied load. It is typically represented by the symbol EI, where E is the modulus of elasticity and I is the moment of inertia of the member.
The stiffness factor for a member in a beam is calculated by multiplying the modulus of elasticity (E) of the material by the moment of inertia (I) of the member. The formula is EI = E x I. The resulting unit for stiffness factor is force multiplied by length squared (kN.m2 or lb.in2).
The stiffness factor is an important parameter in beam design because it determines how much a beam will bend or deflect under a given load. A higher stiffness factor indicates a stiffer and stronger beam, while a lower stiffness factor may result in excessive deflection or failure of the beam.
The stiffness factor plays a crucial role in determining the overall behavior of a beam structure. It affects the deflection, bending moment, and shear forces experienced by the beam, as well as its ability to support loads and resist external forces. A higher stiffness factor results in a more rigid and stable structure, while a lower stiffness factor may lead to excessive movement and potential failure.
The stiffness factor of a member in a beam can be influenced by several factors, including the material properties, cross-sectional shape and size of the member, and the type and magnitude of the applied load. Additionally, boundary conditions and supports can also affect the stiffness factor of a beam member.
