Software Performance of Risk-Targeted Maximum Considered Earthquake (MCER) Calculation
Website software (WS) for Risk-targeted Maximum Considered Earthquake (MCER) acceleration calculation was announced in 2019. Single user non website software (stand-alone software/SAS) was also released in June 2020. The MCER acceleration is divided into three different values MCEG (peak ground acceleration), MCER-SS (short period) and MCER-S1 (1-s period) spectral acceleration. The purpose of the SAS software development is to help civil engineers living in areas having no internet connection or internet connection problems. Both software packages should yield the same MCER result when the same building location or position or coordinate is entered as an input. This paper describes the evaluation of SAS in calculating the MCER compared to the result calculated using the WS. The evaluation was performed at three different islands in Indonesia; Sumatra, Java and Sulawesi islands and at 154, 115 and 81 coordinate positions on these islands, respectively. More than 10% difference in the data was observed when the MCER acceleration was calculated at the area having (MCEG and MCER-S1) greater than 0.6 g (g is gravitational acceleration). The minimum 10% difference in data was also observed when the MCER-SS was greater than 1.5 g. The largest difference was also observed when the coordinate positions were located close to seismic sources (fault source traces).
