“…Similar results were reported by other researchers for reinforced concrete and steel moment resisting frames in references [11][12][13][14]. To elaborate on the differences between the eight pairs of curves, the amounts of the initial stiffness and the load carrying capacities of frames at the ultimate roof displacement limits are extracted and recorded in Table 6.…”

“…Inel et al [9] and Kalkan and Kunnath [10] conducted studies on respectively 3-, 9-tory and 6-, 13-story steel moment resisting frames using various lateral load patterns in the pushover analyses. Similar studies were reported on reinforced concrete moment resisting frames [11][12][13][14] and dual (wall-frame) systems [13]. To the authors' knowledge, there has been no similar study on SPSW systems.…”

IntroductionIn the past three decades, the steel plate shear wall (SPSW) configuration has been widely used as a lateral load resisting system in the regions of high seismicity. A typical SPSW consists of infill steel plates connected to the beams, known as the horizontal boundary elements (HBE); and to the columns, as the vertical boundary elements (VBE). All HBE-VBE connections are of moment resisting type.Many numerical researches have been and are being carried out to study the behavior of SPSW systems via the four available methods of analysis. Two methods are linear, known as Linear Static Procedure (LSP) and Linear Dynamic Procedure (LDP); and two methods are nonlinear, known as Nonlinear Static Procedure (NSP) and Nonlinear Dynamic Procedure (NDP). The linear procedures are appropriate when the expected level of nonlinearity is low. In the SPSW system, the material nonlinearity is considerable as infill plates yield extensively. Therefore, nonlinear methods are proper tools to study the seismic behavior of such system. The nonlinear dynamic procedure, also known as the nonlinear time history analysis, is deemed to be the most accurate method; but it is complex, expensive and time consuming, especially when there are a large number of elements involved. On the other hand, the nonlinear static procedure, known as the pushover analysis, is a more convenient available method to the structural engineers; and is favored by practicing engineers. The nonlinear pushover analysis accounts for both geometric and material nonlinearities in buildings subjected to seismic loads. It also allows the tracing of the sequence of yielding and failure of members, as well as the progress of overall capacity of structures. On the other hand, prior to a cyclic test or analysis, pushover analyses are performed to predict the maximum strength and deformations of structures in order to develop a suitable loading history, evaluate the needs for instrumentation, establish the range of load and deformation measurements, and reduce the risk of unexpected behavior during experiments [1].In addition to the above mentioned applications, the pushover analysis has two further use in SPSW structures.

“…Although the consideration of variable modal properties normally improves the accuracy of the procedure [13,15], its difficulty is inevitably increased and it is somewhat away from the initial objective of a simplified yet accurate method. Moreover, Papanikolau et al [16] pointed out the misleading results that adaptive pushover strategies could offer, and the numerical difficulties involved in the extraction of vibration modes if large inelastic deformations arise.…”

“…Several adaptive pushover methods have been developed in order to 'update' the load distribution pattern along the structure as long as yielding mechanisms are developed, they can be based on imposed load [14] or displacements patterns [15]. Although the consideration of variable modal properties normally improves the accuracy of the procedure [13,15], its difficulty is inevitably increased and it is somewhat away from the initial objective of a simplified yet accurate method.…”

Cable-stayed bridges represent nowadays key points in transport networks and their seismic behaviour needs to be fully understood, even beyond the elastic range of materials. Both nonlinear dynamic (NL-RHA) and static (pushover) procedures are currently available to face this challenge, each with intrinsic advantages and disadvantages, and their applicability in the study of the nonlinear seismic behaviour of cable-stayed bridges is discussed here. The seismic response of a large number of finite element models with different span lengths, tower shapes and class of foundation soil is obtained with different procedures and compared. Several features of the original modal pushover analysis (MPA) are modified in light of cable-stayed bridge characteristics, furthermore, an extension of MPA and a new coupled pushover analysis (CNSP) are suggested to estimate the complex inelastic response of such outstanding structures subjected to multi-axial strong ground motions.

“…The aim of Pinho and Antoniou (2005) was to verify the suitability of the Displacementbased Adaptive Pushover procedure (DAP), proposed in a previous work by the same authors in order to overcome limitations identified in the more traditional Force-based Adaptive Pushover methods (Antoniou and Pinho 2004). To this end, the DAP procedure was applied to a 4-storey building (tested at the JRC) characterized by relevant stiffness/strength variations at the third storey level, and yielded more accurate results in terms of deformation profiles and capacity curves.…”

The paper presents an overview of the progress in research regarding seismic response of plan and vertically irregular building structures. Three areas of research are surveyed. The first is the study of the effects of plan-irregularity by means of single-storey and multi-storey building models. The second area encompasses passive control as a strategy to mitigate torsional effects, by means of base isolation and other types of devices. Lastly, the third area concerns vertically irregular structures and setback buildings. Although fewer papers have been published in this last area with respect to the former ones, this state-of-theart reports extensively on research efforts and progress into the seismic behaviour of irregular buildings in elevation to show the growing interest among specialists in the field.
