The Characteristic Research of Long-Period Response Spectrum Recorded in Guerrero Seismic Network
Zang Mingming · Journal of Qingyuan Polytechnic · 2009
It is to use microseism records from Guerrero seismic network located in Pacific coast of Mexico,and group them in terms of magnitude and epicentral distance,then to calculate their average absolute acceleration response spectrum with a cycle to 10s,analyze the effect of magnitude and epicentral distance to the long period portion of response spectrum,and use average response spectrum to analyze one long-span bridge structure.The results showed that more long-period portion are included in seismic records with larger magnitudes,and more intense seismic response for structure.And the epicentral distance has particular effect on the appearance of long-period part.
