For compression members, the Ɪ-section is preferred because it ______.
has a lower weight for the same strength
For compression members (columns/struts), the critical failure mode is buckling. The Euler buckling load Pcr = π²EI/Le² depends on the moment of inertia I. The I-section efficiently distributes material far from the centroidal axis, giving a high moment of inertia (and high radius of gyration r = √(I/A)) relative to the cross-sectional area. This means for the same compressive strength, an I-section uses less material/lower weight than a solid rectangular or circular section.
The structural member carrying compressive load in a truss is called:
The maximum slenderness ratio of a compression member which carry loads resulting from dead loads and superimposed loads
A strut is a structural member subjected to
Effective length of steel column effectively held at both ends in position but not restrained in directions is ‘x’ times its length between two ends, where ‘x’ is equal to
