摘要
我国对于型钢混凝土框架结构的震后损伤等级没有明确的划分,为了进行型钢混凝土框架结构在地震作用下损伤评估的量化研究,采用层间位移角作为评价指标,该指标具有实用性和简洁性,易于被工程师所接受。基于已有文献的31组试验,并考虑结构构件和非结构构件的破损程度,提出具有一定概率保证的型钢混凝土框架结构地震破坏等级对应的层间位移角限值。
In china,there is no clear division of post earthquake damage grade of steel reinforced concrete frame structure. In order to study the seismic-damage quantitative assessment of steel reinforced concrete( SRC) frame structure,the story drift angle,which is practical and simple,is used as the evaluation index,and it is easy to be accepted by engineers. Based on 31 sets of experiments in the existing literature and consideration of the damage degree of structural members and non structural members,the story drift angle limit values of SRC frame structures with certain probability are proposed corresponding to the seismic damage level.
