| Abstract: |
On 5th May 2014, the Mw 6,1 Mae Lao earthquake occurred at a depth of approximately 6 km in the northern Thai province of Chiang Rai, which caused extensive damage to the community, and spread to Bangkok, an epicentral distance of 670 km, where tall buildings swayed. This paper evaluates the seismic performance of an existing 26-storey reinforced concrete (RC) building with vertical irregularity located in Bangkok, Thailand. The understanding gained from this evaluation can be used to propose effective control measures for similar existing high-rise RC buildings. As the building was constructed in 1990, the structure no longer meets the new Thai regulation. As a result, the building may have sustained significant damage, and an assessment had to be conducted according to the Thai Ministerial Regulation B.E. 2564 (2021). A seismic safety evaluation was applied by using the nonlinear time-history analysis (NLTHA) which was performed by the software ETABS 18.1.1. |
