“…In this state, model SW6 satis es the above conditions and is the best model among all. Figures 10,11,12,13,14,15,and 16 show the 3D view of models SW1, SW2, SW3, SW4, SW5, SW6, and WSW. Figure 17 illustrates the percentage variation of the immediate occupancy damage level; Figure 18 illustrates the percentage variation of the life safety damage level; and Figure 19 illustrates the percentage variation of the life collapse prevention level.…”

“…Ultimately, this study demonstrated that seismic fragility analysis for SRC-framed structures is more cost-effective and trustworthy. Barros et al [15] developed different structural design procedures for frequent and infrequent earthquakes, which are limited to less-period, two-story concrete frame structures. In this study, the design procedures were compared, and then designs for special moment-resisting frames and intermediate frames were developed.…”

Although it is impossible to predict the time or location of an earthquake, it is possible to predict the likelihood of a failure after it hits. Six models with different placements of the shear walls are used in this study to predict the probability of failure through fragility curve analysis. For the fragility curve analysis, each model with 40 earthquakes goes through a nonlinear time history analysis. When developing fragility curves, uncertainty is also taken into account. Uncertainties are commonly associated with construction quality, modeling, and materials. After 280 nonlinear time history analyses, the maximum response for each model is determined, and a fragility curve between PGA and probability of exceedance is performed. The SW6 model performs well in the face of seismic action, with damage levels such as immediate occupancy, limit state, and collapse prevention falling within acceptable limits. For a PGA of 0.5, all of these probabilities of exceedance are noted.

“…Furthermore, the SMF system is often found in middle-low-rise buildings in regions where reinforced concrete is most popular than other building systems. The construction of low-rise buildings based on the frequent earthquake reaction spectrum necessitates considering several parameters, including the building's weight, height, and stiffness [12].…”

Technological developments in material strength and earthquake-resistant reinforced concrete design still need to be implemented in areas with economic growth at the national average or below. The areas have a highly typical building design with a low to moderate category and will inevitably apply code requirements in line with the technology acceleration. Thus, it is necessary to provide a transition scheme of structure with normal to high-strength materials regarding their effectivity in construction, especially for middle-low rise buildings. This research examines earthquake design variables, i.e., response modification factor (R) and base shear design of some typical stories. We analyzed the structure with mixed concrete and steel reinforcement grades to 4-,6-,8-, and 10-story done in Midas Gen with pushover analysis. The data from the result analysis was then scrutinized to capture the structural performance. The analysis of the transition scheme of structure from normal to high-strength materials shows an increase in the strength of the structure to withstand shear forces. The structure ductility and drift differences for each approach scheme differ from the differences in the R-value representing structure ductility. Normal concrete and high-strength steel deliver better performance than other combinations. Normal Concrete-High Strength Steel's transition scheme demonstrates an adequate structure performance.

“…Their earthquake code has been updated to consider recent ground accelerations due to earthquakes. In addition to the response spectrum, details of the structural design have been improved further, as given by Okamura in [5], Karakostas,et al in [6], Sezen, et al in [13], Ergün, Kiraç and Bacsaran in [14], Mosleh, et al in [15] and Baros and Santa-Maria in [16].…”
