Abstract |
It is necessary to consider the support settlements as loads in the structure analysis of building structures or bridge structures. Especially, in the case of a close safety investigation considering deformations or a structure analysis considering support settlements, support settlements should be considered as load conditions. Most of commercial computer programs like sap2000, midas-Gen, and so on, provide this function fortunately. However, since these computer programs only present the concept and the way of using the commands according to each programs, we can not understand the basic theories and programming methods. Also, since consideration of support settlement as load is a kind of programming technique, literatures on FEA do not deal with this subject. So, it is necessary to establish the basic theories and the programming techniques to consider support settlement in structure analysis. This study presents the concept and the programming method considering support settlement as load. Basic theories for the consideration of support settlement are studied first, where some of possible methods are investigated and presented. On the basis of these theoretical backgrounds, theoretically the most reasonable method and an available algorithm is derived, and then a computer program(sNs) is developed based on the theory and algorithm studied. Lastly, a sample analysis is performed to verify the possibility of application of sNs. |
