In the recent years, the issues of seismic safety of dams have become a major concern in the planning and designing of new dams proposed to be built and for safety evaluation of existing dams in seismic regions. Prediction of the performance of the dams during earthquakes is one of the most challenging and complex problems found in the field of structural dynamics. In this book we are going to cover a wide range of topics in the field of seismic performance of various types of dams due to far-field earthquakes. The case studies have been chosen from Malaysia region. Peninsula Malaysia lies in the Eurasian Plate and also within the Indian-Australian Plate. Geologically, small faults also exist in East Malaysia. Records have shown that we do sometimes experiences some off-set tremors originating from the Indonesian zone. Thus there is a need for some seismic checking to be incorporated in the design process so that the structures would be resistant to earthquake.
