Structural Performance Monitoring System Using Android RViSITS For High Rise Building

Abstract

In 2017, Indonesia’s National Earthquake Study Center (PuSGeN) issued an updated Indonesian sources and potentials of earthquake map which shows the possibility of new earthquake hazards potentials. This triggers the assessment of building’s vulnerability towards that new earthquake hazard potential. The assessment of building vulnerability towards earthquakes is divided into two types; quick check using Rapid Visual Screening (RVS) and thorough check. In its development, RVS method was chosen because it does not require a lot of personnel, reduce time for survey, and requires lower research costs. However, RVS method that uses manual form is considered less effective for buildings with a large numbers. Nevertheless, with the existence of RViSITS android application which has developed by ITS’s RVS Team based on FEMA 154, the assessment of building vulnerability and the result can be done and accessed by all sectors quickly and easily. This article aimed to assess the vulnerability level of three high-rise buildings (8-15 floors) in East Java using RViSITS android application by comparing the result of numerical analysis based on earthquake regulations applicable in Indonesia according to SNI 1726:2012. The result of analysis using RViSITS showed that the level of vulnerability of three high-rise buildings studied is “qualified” or earthquake safe. Based on numerical analysis, it shows that the control result of base shear, mass participations, structure periods and driff control are appropriate as required by SNI 1726:2012. Generally, RViSITS can be used to map the vulnerability of high-rise buildings throughout the region in Indonesia.

“…From the research by Taufik Alfianur Wibowo that is the research using cable to transmit the data and the display using seven segment [13][14][15][16]. This research is improved by Sultan Al Badrul Munir, the data transmission using Bluetooth wirelessly with range up to fifteen meter [17][18] [19]. But the transmitter is branched by four items so it will so close [20][21][22][23] [24].…”
