Earthquake Engineering: Date: 11.25.2022 Professor: Engr. Carol Grace Alcid-Gavino

The document summarizes two sample problems covered in an earthquake engineering lecture. The first problem involves checking the seismic serviceability of a special concrete moment frame by calculating story drift ratios from given story displacements and comparing to drift limits. The second problem involves constructing a design response spectrum for a location in Manila given data on soil type, risk coefficient, importance factor, and structure period. The lecture also announced upcoming quizzes and exams to assess students on the covered material.
