One of the objectives of the ongoing ATC-148 project is to strengthen the technical capacity of local stakeholders on seismic risk analysis and design of risk reduction strategies. Accordingly, the project team is conducting training sessions in Uzbekistan and the Kyrgyz Republic in 2019. The following resources are compiled here for training attendees. All listed resources are available for free download.

Yang et al. [1] proposed a lateral load pattern, as an estimation of distribution of the inertia forces of the multi-degree-of-freedom structures. Hosseini and Yaghoobi [2] developed the pushover analysis for asymmetric 3D structures. Their studies focused on asymmetric 8-story steel structure. In this study, the coefficient of 1.7 was recommended for multiplying the lateral forces of earthquake. This suggestion has agreement with the suggestions of many worlds' famous codes in this field. Chopra and Goel [3-4] developed a pushover analysis process based on the structure dynamic theory known as modal pushover analysis (MPA). Comparison of the maximum nonlinear response of a 9-story structure and the offered method shows that this process provides a good estimation of the roof displacement, inter-story drifts and determination of plastic joint location. Moreover, they developed the MPA for asymmetric structures [5]. Kalkan and Kunnath [6] carried out the alternative multi-mode pushover analysis on 8 and 12-story steel structures with SMRF system. They concluded that proposed method provide more appropriate estimations of inter-story drift and the roof displacement in comparison with the load patterns proposed by FEMA. Matsumori et al. [7] compared the distribution of story displacements and ductility demands of members with the obtaind results from IDA and pushover analyses. This study is done on deformation demands of members in the seismic design of reinforced concrete structures. They indicated that if the lateral force distribution were taken to be the sum and the difference of the first two modes, the results provide a reasonable estimate of the distribution of deformation demands of members during an earthquake. De-La-Colina et al. [8] evaluated the pushover analysis by considering the interaction of the flexural moment and the axial force of the columns in low-rise concrete structures. They concluded that this interaction has not significant effect on the capacity curve of the structures. Abhilash et al. [9] compared the capacity curves of a 4-story concrete structure with SMRF considering four lateral load patterns: uniform load adopted from FEMA-273, the equivalent lateral load proposed by FEMA-257, the load pattern suggested by the Indian standard (IS 1893_2002) and the upper band pushover analysis (UBPA) suggested by Janetal in 2004. They concluded that the capacity curves of the structure in four load patterns are almost close to each other. Weixing [10] compared the capacity curves from IDAs and the pushover analysis for two concrete structures. He introduced a load pattern well-known parabola pattern as given by Eq. (1):

The static and nonlinear dynamic analyses of the structures have been carried out by the SAP software [14]. The P-Δ effects have been considered in the seismic analysis of the structures. Also, the moment-curvature nonlinear equation of the columns and beams, proposed by the FEMA-273 [15], are used to assign the nonlinear properties to the structural elements.
