In order to develop coal energy to deal with oil crisis, in2001 the country carries out the "Coal Replacing Oil Program", which is the key object in energy domain. In the Eleventh Five-Year Development Plan of Coal Industry, the Coal Replacing Oil engineering should be prompted orderly to lay the foundation for industrialization development in later 10 years. The operating requirements of Coal Replacing Oil engineering decide that the structure is high, and the equipment is huge. The dynamical interaction is omitted in traditional seismic designs, and the equipment is treated as equivalent load and putted on the structures, which is obviously can't reflect the real dynamical response of structures and equipment. In view of the importance of the plant and design defect, it is the dynamical interaction of the structure and equipment in coal gasification building that is studied though experimental aspect in the paper.A 1:25 simplified shaking table model including the structure and equipment is designed according to similarity theory and equivalent principle of structural static and dynamical property. The seismic wave loading and testing program is also designed. The dynamic characteristic and response of simplified modal is calculated and similar to the prototype by using finite element software ANSYS. By means of inputting waves of different characteristic site periods and changing the direction of seismic waves, the shaking modal section is calculated, and the dynamical interaction of the shaking model is analyzed in two comparison cases of considering and neglecting the dynamical action of equipment.The simplified model is similar to the prototype and the simplified method is proved feasible though the analysis and comparison of the model with prototype by ANSYS, which is helpful to later simplified model tests designs. Through time-history analysis in different earthquake waves, the seismic response is calculated and dynamical interaction is analyzed. The dynamical effect of the structure is reduced; however the effect of equipment is magnified after considering the dynamical interaction. Some results are helpful to later experiment and similar engineering researches.
