Abstract

On 26 December 2004. Malaysia was affected by the Indian Ocean earthquake. Despite
its proximity to the epicenter of the earthquake, Malaysia escaped the kind of damage
that struck countries thousands of miles further away. Since the epicenter was on the
western coast of Sumatra, the island largely shielded the country from the worst of the
tsunami. Structures and buildings in Malaysia are design in accordance to British
Standard (BS) which neglect seismic loading. This research aims to estimate the fatigue
life of reinforced concrete beam-column joint under moderate earthquake loading. A case
study is chosen base on existing structure which is a school. Lightly reinforced concrete
beam-column joint is selected and 5 samples were constructed. Samples are put under
seismic loading and investigations on load and deflection were conducted. Theoretical
study was conducted using STAAD Pro by modeling the whole structure undergoing
seismic load in the form of time-history data, obtained from Siukuai Island, Indonesia.
The result of displacement response is later used to calculate the stress of structure during
earthquake. It was observed that the maximum displacement of the structure under the
earthquake load is 5.45 mm, while the fatigue damage of the structure due to the
equivalent cyclic loading is 28%. Hence, a structure in Malaysia undergone an
earthquake with VI MMI will have 72% of fatigue Iife remaining.
