“…It is because with the same span, the height increased and the stiffness is decreasing, therefore the natural period of first mode is increasing. These results confirm the theory of natural frequency mentioned by Chopra ) and the analysis by Maulana et al (Maulana, Faturrochman, & Saito 2019) that building's natural period is depending on the mass and stiffness. Since the mass is uniform, the increase of the height weakened the building stiffness, thus the natural period increased along the increase of height-to-span ratio.…”

Many type irregularities exist in reinforced concrete frame buildings to accommodate the demand from architectural and aesthetic aspects. One of it is vertical irregularity setback. Its appearance affected the building seismic performance and the damage distribution. Previous researchers proposed equations to correlate between irregularity indices and damage index ratio of setback buildings. However, the aspect ratio between span and height were not included in the formula. This research presents the influence of span-to-height ratio to damage index ratio of the reinforced concrete buildings with setbacks. A set of 2D RC frames having setbacks are evaluated with nonlinear dynamic analyses under three seismic input motions. Several span-to-height aspect ratios were applied by changing the inter-story heights. The Park-Ang damage index was adopted to evaluate the damage index ratio between tower part and base part to represent the damage distribution and the inter-story drifts were observed to represent the building seismic performance. The result showed that under the same earthquake motions, the decrease in span-to-height ratio majorly increased the maximum inter-story drifts. The damage index ratio values between tower part and base part fluctuated, however the similar pattern of damage distributions between tower and base structure were obtained.

“…Saito (2016) melakukan penelitian mengenai respon bangunan bertingkat tinggi dengan periode gempa yang panjang menggunakan aplikasi STERA 3D menggunakan analisis time history. Selain itu beberapa penelitian ditemukan juga dengan menganalisis respon bangunan beton bertulang dengan aplikasi ini (Tanjung et al, 2019;Maulana et al, 2019;Zega et al, 2020). Dari seluruh penelitian tersebut menunjukkan bahwa aplikasi STERA 3D yang berasal dari Jepang ini cukup mampu untuk mengevaluasi penampilan bangunan beton bertulang dalam menahan beban gempa menggunakan metode analisis time history.…”

This study investigated the behavior of high-rise reinforced concrete structures with vertical irregularities caused by seismic loading. The ability of the building to endure all of the load during operation should be considered in design process. The irregularities in the building cause to impair stiffness and performance of the structure, particularly during the earthquake. Therefore, it is necessary to evaluate the effects of vertical irregularities on building, especially high-rise buildings. This study employs an S-Shaped structure with five vertical irregularities. Numerical analysis was used by using STEDA 3D software. The dynamic load used is based on time history data from the previous earthquakes, including the El-Centro, Kobe, and Parkfield. The seismic behavior evaluated in this study consist of shear force, lateral deformation, structural stiffness, the relationship between base shear and top displacement, drift ratio, maximum acceleration response, capacity curve, and top orbit of the building. Based on the numerical analysis results, it can be concluded that each model has a different seismic performance even though it is given the same earthquake load and material properties. The vertical irregularity of the building greatly affects the behavior of the structure due to seismic analysis.

“…The results show the level of performance of the building and its displacement resulted from including the history of time, compared to the displacement limit of [2]. The results showed that the initial performance level was indicated with spectral displacement achieved at 13 cm [21], in pushover analysis that met the height limitation of 0.01 refer to [2]. The ETABS program has provided the facility to conduct structural performance evaluations with appropriate pushover analysis [2].…”

An investigation into the performance of the building structure in receiving the earthquake load must ensure that the building structure is able to receive it within safe limits. A non-linear approach is generally done through pushover analysis. The purpose of this study is to find out how the behavior or performance of building structures when receiving earthquake loads. The analysis is carried out by modeling the structure of the building using the help of the STERA 3D application. Then it is done by entering the Kobe earthquake spectrum data into the software. From the results of the analysis, the value of the deviation between directional levels X 0.0058 m with a base shear of 10,090 KN was obtained. While the Y direction capacity curve has the largest displacement of 0.0084 m with a base shear of 13,270 KN. The result of structural deviation when the performance point is reached for X direction and Y direction loading of 0.0042 m and 0.0063 m, resulting in a yellow color at each point of the column and beam relationship which means that it is still within the range of 1 U 5 (AMP (response force) analysis), this indicates that the condition of the building structure remains safe during an earthquake.
