This study presented different expected failure modes for reinforced concrete frames with CLT (cross laminated timber) based on combination of finite element model and experiment test of small component compression test.The main achievement are as follows: 1.Several failure modes for RC frames with CLT infill were investigated and evaluation method was proposed. 2. New additional experiment was conducted and a combination of experiment results and analysis were used for the analysis. 3. Clarification of the influence of CLT compression strut width and CLT-to-RC shear connections and the probable failure mechanisms. 4- An analysis model using a simplified macro-model were proposed for simulation of the developed hybrid system.
