Most of the residential buildings in Malaysia are not designed to withstand the seismic forces, while the high-rise buildings. However, since the Sumatra 2004 earthquake, there had been increasing concerns about the structure vulnerability in our country to earthquakes. Several recent studies had also revealed that Malaysia had the possibility to be influenced by both local and far field earthquakes. This study is conducted to analyze the vulnerability of a high rise building to local and far field earthquakes using Scia Engineer. Modal Response Spectrum method of Scia Engineer is used. The model is a 12 story hotel building from Ipoh, Perak. The designing code is the Eurocode with Malaysia Annex. Different Peak Ground Accelerations (PGA) that represents the local and far field earthquakes is acted on the model to obtain the seismic performance. The deformation of the building by the seismic combinations is compared to the ASCE-7 design to evaluate the vulnerability. Research of seismic performance of the flat slab system is also conducted along with beam frame system. The result shows that the building is in a safe condition in terms of deformation and the seismic performance of the flat slab system is advantageous.

Ground Motion Records

The construction of reinforced concrete (RC) buildings with flat-slab systems has become widely used in some high seismicity European countries. This type of structure is particularly common both for office and residential buildings, taking advantage of the reduced floor height to meet economical and architectural demands. Even though some national codes may include rules for the design of these structures, the provisions of Eurocode 8 don’t cover flat-slab frames used as part of the lateral load resisting system. Main results of seismic analyses performed on a six-story RC flat-slab structure are reported in this study. The structural response was predicted using both nonlinear static and dynamic analyses with artificial ground motion records with increasing intensity levels. Different seismic retrofit techniques were applied to enhance the seismic performance of the structure including: 1) insertion of shear wall; 2) confinement of column plastic hinge regions using FRP wrapping; 3) addition of RC column jackets. The predicted seismic performance of the retrofitted models was compared to that of the unretrofitted counterpart. Numerical investigations provide information about the seismic performance of a common type of RC structure not covered by the provisions of Eurocode 8 as well as the potential to mitigate the damage for varying earthquake intensity levels through different retrofit techniques.

Tall buildings structure has been a considerable increase in both residential and commercial as well as modern Trend structures. There are two systems comprise the most attractive and commonly used now a days are flat slab and shear wall system. Flat slab is most widely used system in reinforced concrete construction in offices, industrial buildings etc. It supports floor slab without beams. When it comes to seismic performance or lateral force flat slab tall buildings without shear wall is relatively less when compared to with shearwall.in this study I have done two models of flats slab tall buildings one with shear wall and another one without shear wall by using ETABS software. The comparison of analysis results will take place in order to see how both a buildings are performing under lateral and seismic loads and finding a seismic parameters like time period, base shear, lateral displacement, and storey displacement are checked out.
