Three types of building models were tested by repeated and reversal horizontal loading to investigate the collapse mechanism of the models. Type 1: fixed on rigid base. Type 2: supported by piles in a very weak soil model which consisted of Kaolin clay with cement. Type 3: supported by piles in a weak soil model which consisted of Kaolin clay with cement. For Type 1, all beam and column edges yielded up to the plastic strength of 3.5 tf as the testing result. For Type 2, the pile heads and edges of footing beams yielded at the plastic strength of 1.7 tf. For Type3, pile heads, edges of footing beams and edges of members yielded at the plastic strength of 3.1 tf. Nonlinear frame analysis for the models with and without soil springs were carried out to compare with the test results. Experimental results were simulated very well by this analysis for Type 1. For Type 2 and 3, results of analysis showed good agreement with experimental results for the load-deflection relationship but there is a little difference for the collapse mechanism of super structure.
