英文摘要	Incremental dynamic analysis (IDA) is a useful method in performance-based earthquake engineering. IDA curves combine the intensity measure (IM) of ground motions with structural responses (as measured by engineering demand parameter) from nonlinear dynamic analysis. However, the curves display large record-to-record variability. And various IMs can lead to different results. Therefore, it is important to find a desirable IM to reduce the discreteness of the IDA results. So far, the studies on IM for IDA have been carried out by many scholars from scalar-valued to vector-valued, but few were based on 2-dimensional ground motion input. To make the analysis more reasonable and practical as well as investigate the desirable IM under 2-dimensional ground motion input, incremental dynamic analyses when ground motions are inputted in 2 directions should be investigated. In this paper, 2 combinational types of area-based IM incorporating the influence of ground motion record components in secondary directions were proposed. To investigate the applicability, efficiency and desirable combinational form of the area-based IM under 2-dimensional ground motion input, incremental dynamic analysis were carried out using 2 reinforced concrete frames. Then the efficiency of the IMs was measured by the residual sum of squares and R-2. It is concluded that the area-based IM with a combination by the square root of the sum of the squares (SRSS) method is the most efficient for IDA under 2-dimensional ground motion input. The methods and conclusions will provide significant reference for studying IMs under 2-dimensional ground motion input. Further research will focus on the applicability of the area-based IM for tall buildings whose higher modes need to be considered.
