Lecture
This lecture covers the Capacity Spectrum Method, a graphical procedure to compare the displacement capacity of a structure to the displacement demand for seismic intensity. It includes the representation of seismic demand and capacity, safety factors, and the transformation of MDOF systems into SDOF systems. Advantages and disadvantages of the method are discussed, along with examples of retrofit strategies and pushover analysis. The lecture also addresses the evaluation of seismic behavior of a bridge pier using the Capacity Spectrum Method.
