What is squash load?(a) load at which member will not deform axially(b) load at which member deforms laterally(c) load at which member deforms axially(d) load at which member will not deform axiallyThe question was posed to me in final exam.The question is from Behaviour of Compression Members & Types of Sections topic in chapter Design of Compression Members of Design of Steel Structures

Answer» RIGHT CHOICE is (c) LOAD at which member DEFORMS axially

Easy explanation: Large deformation is possible only when fc REACHED the yield stress. At this stage the member deforms axially. The value of axial force at which this deformation occurs is called squash load.
