Types of Supports in Structural Analysis: Reactions, Examples, and Modeling Assumptions

Most structural models require supports or boundary conditions to define structural behavior. In structural analysis, however, a support is represented as an idealized boundary condition that…

I-Beam vs H-Beam: Difference, Strength, and When to Use Each

Most H-beam vs I-beam comparisons stop at shape: H-beams are wider and heavier, while I-beams are narrower and lighter. That…
