Abstract
This paper describes the lecal parameter (story stiffness and damping coe 伍 cient)estimation method directly using absolute acce ］ eration records ． This method consists of 2 steps ， The first step estimates atl moda ［ parameters by abso 】 ute acceleration pu 【 se response fUnction method ． In the second step ， stQry stiffness and damping coefficients are evaluated by 亡 be theory re 【 a 亡 iQnship beし ween modal and local parameters ． With this method ， not enly the ］ ocal parameters but also those probabMstic errors can be easi ］ y eva ［ uated 、 In addition ， it is possible to evaluate the frequencydependent properties ofthe loea ］ parameters． The applicability ofthe method isclarified by both numerical simuiation data and experimental data ． 互 t is fbund that the mcthod exactiy estimated t1 、e stQry parameters， lnciuding those frequeney dependencies．This publication has 11 references indexed in Scilit:
