I am Alyannah Terite, a 5th BS Civil Engineering student at the University of the Philippines Diliman. I am currently conducting a thesis undergraduate study on the Analysis of Soil-Structure Interaction: Dynamic Response of LRT-2 Foundation due to Earthquake Loading. The general objective of the study is to analyze the effects of soil-structure interaction (SSI) due to earthquake loading and its application on the dynamic response of LRT-2 foundation. The bridge spans that I will analyze are between: 1. Santolan and Katipunan 2. Betty Go-Belmonte and Araneta Center
The specific objectives are: 1. To utilize RS3 for the modeling and simulation of the behavior of LRT-2 foundation during an expected strong ground motion generated in the West Valley Fault (e.g. The Big One) 2. To develop a methodology for incorporating soil-structure interaction in the foundation structural analysis. 3. To provide key parameter inputs for a possible structural retrofit of LRT-2 foundation members due to the effects of soil-structure interaction for expected strong ground motion The study will be focused on the analysis of the seismic vulnerability of the bridge span between Santolan and Katipunan which lies on soft soil and on top of the West Valley Fault. However, to determine the effects of SSI on different conditions and its comparison to this critical section, I will also analyze the bridge span between Betty Go-Belmonte and Araneta Center-Cubao since this lies on stiff soil or bedrock. My focus is on structures on soft soils since SSI is detrimental on these structures because it further aggravates the seismic response of the structure. The study will be beneficial to the current design specifications since the incorporation of the soil-structure interaction in the design procedure will result in a realistic estimate of the dynamic response of the structure. It will also provide a modern computational framework for specific foundation structural analysis. Lastly, the possible damage or collapse of LRT-2 when subjected to strong ground motion will be avoided due to the structural retrofitting of the necessary members. Rest assured that all these documents will remain confidential and will only be used for this research study. I hope that I’ll be able to receive these documents by the first week of January since I will start the modelling and simulation on the second week of January, 2020 so that I can finish the whole research study by May of the same year. Should you have any questions or updates, you may contact me at 0997 609 5272 or email me at [email protected]. I look forward to hearing from you and I thank you in advance for your time.
