Researchers in Taiwan and Unite States proposed to test full scale 3-story 3-bay RCS in-plane frame at NCREE, Taiwan in 2002. In advance, some sub-structures, including exterior cross panel with slab, T-joint panel of roof and RC column, need to be tested before the design of in-plane frame. Therefore, nonlinear analysis for sub-structure tests was first modeled by Drain-2DX program. Based on these simulations, push-over analysis of in-plane frame was performed and compared with pseudo dynamic test, in order to validate the strength and stiffness of the models. Finally, pseudo dynamic simulations were performed and compared with tests. Based on the comparison of experiments and theoretical analysis, it was shown that the strength and stiffness of sub-structures can be predicted reasonable by Drain-2DX, despite different parameters in panel zone for specimens. However, due to some limits in Drain-2DX, it was found that there are some difference in hysteretic loop. For the modeling of full scale frame, push-over analysis shown that stiffness of whole frame was similar to the pseudo dynamic test. However, in dynamic simulations, it was found that theoretical frame have higher stiffness and better energy dissipation abilities, this is because the slip of cover plate and bolts in beam splice and concrete deterioration were observed during tests.
