Endurance time (ET) method is a dynamic structural analysis procedure in which intensifying dynamic excitation is used as the loading function. An estimate of structural response and/or performance at the entire seismic intensity range of interest is obtained in each response history analysis. The concept of endurance time analysis is similar ...
A modal analysis calculates the frequency modes or natural frequencies of a given system, but not necessarily its full-time history response to a given input. The natural frequency of a system is dependent only on the stiffness of the structure and the mass which participates with the structure (including self-weight).
Seismic analysis is a subset of structural analysis and is the calculation of the response of a building (or nonbuilding) structure to earthquakes. It is part of the process of structural design , earthquake engineering or structural assessment and retrofit (see structural engineering ) in regions where earthquakes are prevalent.
Computers and Structures, Inc. (CSI) is a structural and earthquake engineering software company founded in 1975 [1] and based in Walnut Creek, California, with additional office location in New York. [2] The structural analysis and design software CSI produce include SAP2000, CSiBridge, ETABS, SAFE, PERFORM-3D, and CSiCOL.

The FDM is ideal for the analysis of cable structures whereas the DSM is the most widely used technique for the analysis of framed structures. The nature of the structures under consideration lead to the development of this analysis technique which is a combination of the two methods. ATLAS handles the wind loading in a realistic manner.
