The roof crush resistance test of a 4WD vehicle is especially getting more attention. The object of this paper is to understand the effect of BIW(Body In White), door, windshield glass and etc on roof crush resistance. Quasi-static analysis using the PAM-CRASH are carried out for the roof crush resistance studies. Finally the analysis results are compared with the test results.<br/>
