Seismic strengthening design ground motion parameters for existing buildings with different importance

Zhao Guifeng

Open publisher page 1 citations

Abstract

Sampling principle of seismic strengthening design reference periods for existing buildings with different importance is presented.The conception of three design levels is given.The seismic strengthening design ground motion parameters for existing buildings with different importance are researched in detail by use of hazard curve formulas of seismic ground motion parameters based on seismic hazard characteristic zone.In order to help the designers use this mefhod easily,the simplified method is put forward.At last,the method and calculation step is explained by a calculation example.
