RESEARCH ON DRIFT ANGLES ON WOODEN FRAMES WITH PARTITION BOARD BASED ON VALUE RECOGNITION

As one of the evaluation indexes of structural seismic performance level, displacement angle has been widely applied in specifications at home and abroad. In order to study the relationship between maximum displacement angle and the seismic performance level about wooden frame with partition board, three groups of 1:2 scale models were fabricated according to "Engineering Practice Rule" by the Ministry of Work in the Qing dynasty,and quasi-static tests were carried out. The failure characteristics and mechanical properties of wooden frame with partition board under horizontal reciprocating load were obtained. According to the data obtained by ABAQUS finite element simulation, based on the analysis of the composition of the partition board and its value occurrence form, the seismic performance level of the non-structural member was combined. Considering the influence of cultural relic value and component damage degree on the seismic performance of the partition board, the displacement angle reference limit of the wooden frame with partition at different seismic performance levels was given.
