| Summary: | The vertical housing system is a solution for the urban population growth. Developing high-rise building program at urban area for residential purpose will significantly reduce the problem of land parcel demand. However, high-rise buildings have their own problems, one of which is the structural bending due to the load acting on the building. One major factor that causes bending in buildings is wind load. It becomes a problem when the bending exceeds the structural strength tolerance of the building, which leads to structural failure. Therefore it is necessary to monitor the verticality of building to evaluate the performance and health of the building, during construction stages. Verticality monitoring can be done using GNSS observations, and a triaxial tiltmeter. GNSS observation is used to detect the lateral displacement of the building, while the triaxial tiltmeter is used to detect the deflection angle that is formed when the building is bent. To see whether the monitoring with GNSS observations and triaxial tiltmeter can deliver reliable result. A simulation of structural bending on one of the buildings in Bandung, Indonesia, is carried out, assuming only wind loads work on the building, with a stable soil conditions. Wind load calculation refers to SNI 03-1727-2013. The simulation of bending calculations is carried out based on the beam deflection theory. From the simulation results, it was found that the deflection that occurred at the highest level (76.68 m) reached 2.832 cm, and the largest deflection angle reached 1.792 arcseconds. It can be concluded that these values can be detected by GNSS observations, and the triaxial tiltmeter. Because the accuracy of the two tools is smaller than the simulation result value. Taking this monitoring into account, the performance and health of the buildings can be determined, and then an SLF (Building Fitness Certificate) and building insurance can be issued. |
