1. Introduction
Engineers have been seeking more accurate modeling and investigating of structures under earthquake excitations, and modeling software is constantly developing. Thereby, nowadays, nonlinear modeling and analysis of structures are not really difficult. Incremental dynamic analysis is one of the most powerful analyses, which is used for investigating seismic performance of structures. Although this is a widely applicable method and it can present a lot of precise information about structures, it is really time-consuming, and state-of-the-art computers are needed for investigation of massive structures. All researchers have been seeking efficient methods and software by which they can increase the speed of analyses; thereby, they can obtain more precise outputs during less spending of time. IDA has been used by several researchers for different studies. For example, Mander et al. [1] used it for seismic risk assessment of bridges; Pinho et al. [2] used it to evaluate the accuracy of static pushover methods on twelve bridges, and Goulet et al. [3] relied on IDA to estimate seismic losses for a reinforced concrete frame structure. Inasmuch as IDA is a widely used method for assessing structural performance in recent decades, many researchers have been trying to improve the performance of IDA, and they have presented efficient methods, such as IM selection [4] progressive IDA for first-mode dominated structures [5], use of a trilinear idealization model of IDA for RC structures [6], and implementation of IDA in parallel [7]. As mentioned above, although IDA is really a widely applicable method, it is time-consuming; hence, in this study, strong motion duration is used instead of total motion duration. Although the effect of ground motion duration on liquefaction and slope stability is recognized, its influence on structural response and fragility curves is a debatable topic. Some researchers, such as Ruiz-Garcia [8], Iervolino [9], Raghunandan and Liel [10], have studied on the influence of motion duration, and they indicated that the longer duration record proves more damage to the structure than shorter duration record because the longer duration ground motion imposes high energy demands on the structure. In this regard, most of them considered two different ground motions, whereas in this research one set of ground motion with different motion duration is considered. 2.
