| | Abstract | | The earthquake-resisting capacity of a partially-settled house has been investigated through method of vibration response analysis of microtremors measured on the ground and the building. The natural frequency f, resonant factor Q and maximum response value R have been evaluated of the two-story house. The earthquake-resistant capacity index C has been estimated by means of a empirical formula defined as C = 100TxTxrootQR, T=1/f . The dynamic characteristics f,Q and R of values shoud correlate with the earthquake-resisting capacity and the index C can be used , if C is larger than 40 , houses are dangerous and it is less than 20, those are strong enough. The reform remedy conducted of inclination ,1/1000, improved aseimic examination of the index C values . that is from 60 to 40 in the E-W direction and from 70 to 40 in the N-S direction . |
