- An overview of the methodology and results of a proposed design procedure based upon seismic risk analysis is provided. Seismic hazard conditions of Nicaragua are presented in the form of an iso-contour map, and acceleration zone graphs for the principal cities. The map and the graphs provide the peak ground acceleration (PGA) values of earthquakes for a given return period or having a given probability of being exceeded during a given economic life in years. Topics covered in this report are: seismic hazard zoning; design objectives; definition of structure importance or use classes; definition of the type of structural system; definition and formation of the design spectra; the structural design procedure based on the response spectrum method; an equivalent static force method; and design examples. To demonstrate the use of the design methodology developed in this project, two design examples are given. Example I is a two-story two-bay ductile moment resisting frame. Example II is an existing building in Los Angeles which was originally designed according to the 1964 Los Angeles City Building Code. This building survived the 1971 San Fernando earthquake with minor damage. The building is a fourteen story reinforced concrete shear wall building.
