SEISMIC LOAD ANALYSIS FOR AN AIRPORT CANOPY STRUCTURE

Although the Malaysian peninsula is not located along the active seismic zone compared to Sumatra, the tremors due to Sumatran earthquakes have been felt several times. The earthquakes had caused tremor in several cities in the Malaysian Peninsula along the coastal line with Sumatra such as Penang, Port Klang, Selangor and old Klang. Especially the earthquake near Sumatra which happened on 2nd November 2002 had caused panic among residents living in high rise building in Penang prompting thousands of people to run out from their buildings. The paper summarizes the analysis of seismic loadings on the building structures. The seismic analysis is performed in order to assess the force and deformation demands and capacities of the structure. In the analysis, the effect of the provision of gravity, wind loadings on the structure is considered. In this research work, methods such equivalent static analysis and nonlinear dynamic analysis procedure will be used to evaluate the seismic response of the building structure. The structure is modelled and analysed in STAAD Pro software. The test results of each method used in the analysis of structure performance will be discussed and conclusions drawn by comparing the results of the deformation geometry of the graphs and stresses in the members with the prescribed limiting values.
