The main objective of the thesis is evaluating and comparing Second-Order Elastic Analysis
Methods defined in two different specifications, AISC 2005 and TS648 (1980). There are
many theoretical approaches that can provide exact solution for the problem. However,
approximate methods are still needed for design purposes. Simple formulations for code
applications were developed, and they are valid as acceptable results can be obtained within
admissible error limits. Within the content of the thesis, firstly background information
related to second-order effects will be presented. The emphasis will be on the definition of
geometric non-linearity, also called as P-& / #948 / and P-& / #916 / effects. In addition, the approximate
methods defined in AISC 2005 (B1 &ndash / B2 Method), and TS648 (1980) will be discussed in
detail. Then, example problems will be solved for the demonstration of theoretical
formulations for members with and without end translation cases. Also, the results obtained
from the structural analysis software, SAP2000, will be compared with the results acquired
from the exact and the approximate methods. Finally, conclusions related to the study will
be stated.
