Theoretical natural frequencies and mode shapes for the tracheo-bronchia of the human respiratory system are determined using the finite element method. Radial modes, which are anticipated to be used for contraction relaxation, are identified. It is anticipated that these values will give the initiation for future development of non-traditional techniques of relieving respiratory system constrictions.

In order to analyze aseismic behavior of the high reinforced concrete (R.C.) shear wall with frame column in the large thermal power plant, the model structure has been taken test with method of low frequency cyclic repeated load that has 1/15 scaling factor to practical structure. At same time the model has been analyzed by the finite element method which takes the Hognestad concrete constitutive model and ideal elastic-plasticity steel reinforcement constitutive equation. It has been found that the hysteretic curve is relatively full and energy dissipation capacity is better through the experiment. The bearing capacity, deformation and fracture results to the Shear wall of finite element analysis are closely with the test results. In general, the R.C. shear wall with frame column in the large thermal power plant has good aseismic performance. The finite element method can be taken to analyzed the similarity structure.
