Basic objective of second order elastic analysis is :(a) to calculate external force equilibrium in deformed geometry of structure(b) to calculate internal force equilibrium in deformed geometry of structure(c) to calculate external force equilibrium in undeformed geometry of structure(d) to calculate internal force equilibrium in undeformed geometry of structureThis question was posed to me in semester exam.I'm obligated to ask this question of Methods and Assumptions of Analysis in chapter Structural Analysis, Loading and Load Combinations of Design of Steel Structures

Answer»

Right CHOICE is (b) to calculate internal force EQUILIBRIUM in deformed GEOMETRY of structure

To explain: Basic OBJECTIVE of second ORDER elastic analysis is to calculate internal force equilibrium in deformed geometry of structure. In this P-Δ effect is also considered.
