| Summary: | The vertical housing system is a solution for the increasing urban population over time. By building high-rise buildings, the land used for housing will be more effective. However, high-rise buildings have several problems of their own, such as deflection due to the load acting on the building, one of which is wind load. Deflection becomes a problem if the deflection exceeds the strength of the building structure, which will cause structural failure. Therefore, monitoring the deflection of the building is needed to detect the deflection, which is useful for evaluating the performance and health of the building. In estimating the deflection response that occurs in buildings due to wind loads, the Triangular-Uniform Distributed Load (TUDL) calculation method can be used. The simulation results can then be used as initial data for consideration in determining monitoring methods and tools that are appropriate to the conditions and response of the building due to wind loads. In this research object at Apartment X, Bandung City, the results of the TUDL simulation calculation gave a maximum deflection of up to 16.97 cm to the East. Based on these results, a monitoring method using GNSS installed on the roof of the building was used, and TLS to monitor the response of the building segments below. The results show the same correlation, where the maximum deflection that occurs reaches 20 cm to the East. This response can be caused by 2 types of wind, where the daily period shows the effects of mountain winds & valley winds. While measurements from 2 different sessions show a response to the west monsoon & east monsoon. Even so, based on SNI 03-1729-2002 concerning procedures for planning steel structures for building structures, the deflection that occurs is still within safe tolerance, where the maximum deflection tolerated is 55.3 cm. |
