摘要：	This paper presents a multistep linear elastic analysis (MLEA) method to estimate the nonlinear out-of-plane load-deflection behavior of precast concrete insulated sandwich panels (ISPs), idealized as multiple segments of linear behavior. The proposed method was verified using the results of out-of-plane flexural tests conducted on six precast concrete ISPs, two of which were enclosed by end beams. The MLEA method predicted the experimental load-deflection behavior of the tested precast concrete ISPs with 12% deviation. The results of the MLEA method were also compared with the experimental results of eight precast concrete ISP specimens tested by other researchers; these precast concrete ISP specimens varied in geometry and type of interlayer mechanical connectors. The MLEA method estimated the elastic out-of-plane deflection, cracking, and ultimate strength of the eight precast concrete ISP specimens within 31%, 14%, and 24% margin of error, respectively. This suggests that the MLEA method can be used to estimate the out-of-plane behavior of precast concrete ISPs with any geometric properties and type of interlayer mechanical connectors.
