Abstract
Guadalajara city is the capital of the Mexican federal state of Jalisco. It is located close to the Pacific coast and is subjected to a large seismic risk. We present a seismic response study for some sites along the city. We calculated response spectra of shear-waves by using seismic records of actual earthquakes registered on rock and near the source as Green functions and propagated them trough a flat and horizontal layered media using a linear equivalent method to compare them with the response spectra calculated according to the Federal Commission of Electricity (CFE) seismic design buildings Manual (MOC-2008, 2008) which is widely used as reference on construction projects in Mexico. Our results show that MOC-2008 manual underestimates the spectral amplitudes and frequency band for the response spectra.

It is well known that seismic damage distribution is strongly influenced by physical and dynamic properties of the soil
We calculated response spectra of shear-waves by using seismic records of actual earthquakes registered on rock and near the source as Green functions and propagated them trough a flat and horizontal layered media using a linear equivalent method to compare them with the response spectra calculated according to the Federal Commission of Electricity (CFE) seismic design buildings Manual (MOC-2008, 2008) which is widely used as reference on construction projects in Mexico
In order to estimate the seismic response we chose earthquakes occurred along the subduction zone and seismic records from the closest stations installed over hard rock in order to prevent site effect to be used as Green Functions
Summary
It is well known that seismic damage distribution is strongly influenced by physical and dynamic properties of the soil. Seismic response evaluation is one of the most important problems to solve in seismic engineering. The Analysis of the seismic response of the soil is used to predict the response of the seismic movement in the surface, which in turn is essential to obtain the design spectra to evaluate the risk. Design spectra is a tool that allows us to evaluate the forces to which the structures will be submitted in dependency on its own dynamic characteristics. More modern and greater civil structures have appeared at the whole city (Figure 1). Large buildings appear each year in Guadalajara city.
