In order to estimate the dynamic characteristics of two temples constructed by modern method, we carried out microtremor measurements. The main results obtained from microtremor measurements and analytical investigations are as follows.
Natural frequency of these temples distributes from 4.3 to 5.0 Hz.Torsional angle between first and second floor is about 10-8 rad.
Damping constants for translate mode distribute from 2.5 to 4 % and those for torsional mode distribute from 1.5 to 3 %. Results obtained by an analytical model considering two axis eccentricities satisfactorily coincidences with results obtained by microtremor measurements.
