Dissertation note: College of Engineering.-- Bachelor of Science in Civil Engineering: Technological University Of The Philippines, Manila. 2024 Summary: Earthquakes pose significant threats to human lives and infrastructure, prompting the construction of modern buildings to incorporate seismic resistance through performance-based design. Seismic isolation, a proven technology, minimizes structural damage by decoupling the superstructure from the substructure. This study analyzed the seismic response of the Delpan Evacuation Center under two scenarios: a fixed base design and a lead rubber bearing (LRB) seismic isolation system, using nonlinear time history analysis. The simulations were performed in ETABS v.21.1.0, adhering to ASCE 7-22 and ASCE 41-17 standards. Dynamic response parameters, including base and storey shear, storey displacement and drift, storey acceleration, and overturning moment, were compared. The LRB isolators were designed based on the maximum axial load carried by the columns. Among the trials, Trial 2 exhibited the best seismic resilience. The isolation plane showed increased displacements (184.125 mm to 204.428 mm) due to enhanced structural flexibility. Significant reductions were observed in interstorey drift (0.006 to 0.012, within safe limits), base and storey shear (up to 57.24% in both X and Y directions), storey acceleration (16.43% to 50.54%), and overturning moment (26.26% to 60.64%). These findings demonstrate the efficacy of the designed seismic isolation system in improving the seismic performance of the evacuation center under earthquake conditions. The foundation plan and analysis were transmitted to the local government of Manila, providing valuable insights for the Department of Engineering and Public Works on the benefits of seismic isolation systems for critical infrastructure. This capstone project contributes to advancing seismic isolation technology and fostering further research and development in the Philippines.

Earthquakes pose significant threats to human lives and infrastructure, prompting
the construction of modern buildings to incorporate seismic resistance through
performance-based design. Seismic isolation, a proven technology, minimizes structural
damage by decoupling the superstructure from the substructure. This study analyzed the
seismic response of the Delpan Evacuation Center under two scenarios: a fixed base design
and a lead rubber bearing (LRB) seismic isolation system, using nonlinear time history
analysis. The simulations were performed in ETABS v.21.1.0, adhering to ASCE 7-22 and
ASCE 41-17 standards. Dynamic response parameters, including base and storey shear,
storey displacement and drift, storey acceleration, and overturning moment, were
compared. The LRB isolators were designed based on the maximum axial load carried by
the columns. Among the trials, Trial 2 exhibited the best seismic resilience. The isolation
plane showed increased displacements (184.125 mm to 204.428 mm) due to enhanced
structural flexibility. Significant reductions were observed in interstorey drift (0.006 to
0.012, within safe limits), base and storey shear (up to 57.24% in both X and Y directions),
storey acceleration (16.43% to 50.54%), and overturning moment (26.26% to 60.64%).
These findings demonstrate the efficacy of the designed seismic isolation system in
improving the seismic performance of the evacuation center under earthquake conditions.
The foundation plan and analysis were transmitted to the local government of Manila,
providing valuable insights for the Department of Engineering and Public Works on the
benefits of seismic isolation systems for critical infrastructure. This capstone project
contributes to advancing seismic isolation technology and fostering further research and
development in the Philippines.
