Indonesia is located in a high level of the earthquake risk area. According to USGS data, from December 2004 to October 2009, more than ten large earthquakes occurred and exceeded 5.0 Scale Richter in magnitude. Recently, the major earthquake occurred on September 28, 2018, in Palu City, Central Sulawesi, with 7.4 on the Scale Richter in magnitude and triggered a lot of building damaged. In this study, the seismic capacity of a 3-story reinforced concrete building, which collapsed due to a large earthquake in the city of Palu, was evaluated. The Standard for Seismic Evaluation of Existing Reinforced Concrete Buildings, 2001 from Japan, was used to evaluate the seismic capacity of reinforced concrete. In this analysis only reviews the column structure elements. However, the brick wall elements are considered to determine net column height. The analysis has been done only for the first floor, where there is the maximum shear force on the structure. Seismic capacity is determined by the relationship between the lateral strength and the ductility index. The obtained results of the seismic capacity analysis showed that the total strength index value of the building was 0.307 for the north to south and 0.455. The seismic capacity of this building is compared with the seismic capacity of a reinforced concrete building that survived due to a large earthquake with 7.6 on the Scale Richter in West Sumatra in September 2009. The obtained results show that the strength index value of this building is smaller than that of a building that could survive the 2009 West Sumatra earthquake.

Structural Health

The automated monitoring of a building’s structural health during its exploitation is a way to extend its design life without compromising structural safety.  In turn, it helps increase the rate of building renovation works compared to demolition works, which reduces future construction and demolition waste levels.This research explores the vibration-based global monitoring method application to structurally stiff medium-rise reinforced concrete buildings by analysing predicted building vibration amplitudes and spectrum under regular city traffic excitation. These predictions are based on the results obtained from finite element calculations of building models with variated structural stiffness and inertial mass of the building.Regular traffic-generated ground frequency spectrum differs from the first natural frequencies of medium-rise reinforced concrete buildings, and the vibration energy is low. Nevertheless, it is found that the structural identification of such building dynamic parameters is still possible, particularly natural frequencies. It was found that the ratio between fundamental frequency for the fixed base model of the building and elastic spring foundation model is the decisive parameter for selecting the building part to be monitored. Structural health monitoring vibration-based methods are also a promising technology for medium-rise mass house buildings when tailored according to some damage sensitive feature.
