This document contains an exam for a course on earthquake resistant design of structures. It lists four questions, with subquestions asking about: 1) the difference between static and dynamic loads, capacity based design, and calculating seismic force distribution; 2) usual range of damping in metal frames, types of seismic analysis, and response spectrum analysis; 3) types of seismic tests on models and calculating rebar area for lateral ties; 4) the structural property linked to serviceability, defining interstory drift and overall drift index, and sketching reinforced concrete beam and column sections.

c) Sketch typical beam and column sections and mark the lap zones, zones of
special confining reinforcement.
