Popis: Bridges in Malaysia are usually designed under static loading. Some major cities in Malaysia had experienced earthquake excitation or ground motion upon devastating tsunami and earthquake event held in Acheh back in 2004. Performing simple harmonic motion analysis for the single degree of freedom (SDOF) bridge structure under free vibration without damping using STAAD.Pro is a new adaptive study. The model of the bridge had modified specifications (from existing bridge in Jeli, Kelantan) suitable for dynamic analysis assignment. Commenced with the validation of the static loading for the modified prototype bridge pier structure using mathematical calculation, the comparison shown between analytical and theoretical was almost 0 %. Thus in dynamic analysis, two parameters are verified and validated using theories and calculation, which are maximum lateral displacement and Rayleigh frequency under six various percentages of drift. Numerical results indicate excellent accuracy when the percentage difference between analytical and numerical for maximum lateral displacement and Rayleigh frequency was only 4.705 and 2.18 %, respectively. It has a good accuracy and is acceptable to be used and compared in laboratory experiment of the same specimen for continuity of the study. Both static and dynamic analyses were successfully verified and validated. In supplementary, the free vibration without damping system analysis produces more information and relevant data that merely could be used in researching the performance of the bridge structure under dynamic responses.
