“…This code has been upgraded since 2002 and the earthquake hazard map is updated in 2017. However, not many studies perform seismic evaluation on building based on this code [21], [22]. In this research, 7-storey academic building earthquake response in Yogyakarta is evaluated using STERA_3D.…”

Periodical seismic safety evaluation for concrete buildings are necessary since they have been used for many years. Many approaches can be used to evaluate them, one of them is pushover analysis. This analysis is performed by applying incremental loads then reading the displacement that happen and comparing it to the response spectra demand to retrieve the performance point. Moreover, time history records can be used to determine the displacement appear in structure. This study aims to perform 3D evaluation of reinforced concrete buildings. The building sample was selected from academic building in Yogyakarta, Indonesia which has 7 storeys. The analysis was performed using STERA 3D software. Three timehistory records namely El Centro, Kobe, and Parkfield earthquakes were used to determine the displacement. The result shows the performance level of the building and the displacement resulted from inputting time history, compared to the displacement limit from ATC-40 and FEMA 356. The result shows that the preliminary performance level indicated with spectral displacement is achieved at 13 cm on pushover analysis which complies the 0.01 height limitation from ATC-40 and FEMA 356. Since it is a preliminary study, it is hoped that further study could consider more aspects such as ductility, prediction of failure positions, and comprehensive pushover analysis based on FEMA 356.

“…These results in P-M diagram have given the idea to see the soil characteristic in the location of the building while investigating the building assessment, especially soon after the earthquake. The quick assessment is a very important task to be conducted after the earthquake [5] and [6]. It can be seen that the edge column is at the most critical position in the P-M diagram,…”

A study on the damage pattern of the two-story building is needed for quick assessment soon after the earthquake. In Indonesia, quick assessment is needed at least for two reasons: to determine the Government subsides Fund and to retrofit the damaged houses. The previous article has been analyzed and simulated the case study of the two-story building due to earthquake load base on Indonesia Earthquake Code by considering the soil conditions. It shows that the influence of soil conditions as well as column properties, especially at a lower level, are an important factor in determining the damage patterns. However, that study was not verified yet with the damage data of the two stories building in the field. This paper discussed the comparison between the simulation results with the field record of two stories building damage in Indonesia. The data are collected base on the recent earthquakes in Indonesia: Padang Earthquake ( 2009) and Palu Earthquake (2018). It shows that they are confirmed the damage patterns are in line with the simulation results. Base on this study, the guidance for quick assessment of a two-story building then is developed.

“…When a building failed to withstand seismic loads, it causes damage in various levels, both minor and severe damages, or even collapse [1][2][3]. Indonesia, a country with various seismic potentials, especially in Aceh Province, has seen several high-intensity earthquakes occur in the last 15 years [4][5][6]. e magnitude of the potential seismic load that may be received by a building is determined by some interrelated factors.…”

Seismic loads should be considered in the cost estimation process as a consequence of changes in structural dimensions. Seismic loads received by buildings vary from one region to another, which are used as a basis for dimensioning structural components. This paper aims to investigate the potential cost changes of the reinforced concrete (RC) beam and column elements as an implication of variations in seismic load received by a building constructed in different seismic areas. This study was applied to a prototype of the two-story building. The structure analysis performed with dynamic analysis by varying seismic design categories based on eight seismic zones in the observed area. The utilization of a building prototype was applied to three indices of seismic importance factor to represent the building occupancy category. The results of the study explaining the increase in the total cost of the two RC elements are 0.68%, 1.70%, and 1.54%, respectively, for the seismic importance factor indices of 1.00, 1.25, and 1.50. The variations of the costs due to the factor of seismic load and building occupancy categories indicate that both factors need to be considered in the cost estimation process of buildings.
