Earthquake

This document contains calculations to determine the base shear of a proposed 5-story dormitory building in Pampanga, Philippines. Soil properties, building dimensions, and total building loads are provided. The natural period of vibration is calculated to be less than 0.7 seconds. The maximum, minimum, and design base shear values are then determined. Finally, the base shear distributed to each level is summarized.
