The response spectra for the Faiyum earthquake were selected as the best
earthquake for the most effective zone near Abu Serga church to construct the design
response spectrum for the church. The original acceleration time history was recorded
10 km away from Abu Serga church over the bedrock of Cairo city at Mokattam area
(about 10 Km from Abu Serga church). This is considered to be the first response
spectrum done for all earthquakes that ever affected Egypt. Fortunately, this earthquake
is regarded as one of the most important earthquakes that affected Egypt in the last 100
years. The maximum acceleration response spectrum maintained for Abu Serga church
for the church's fundamental resonance frequency, which is 5.5 HZ, is about 100
cm/sec2 for 5% damping. As for the other resonance peaks for the 2nd wooden floor
and the roof, nearly the same spectral acceleration occurs (0.1 g).
