(1) Figure 1 shows a two-story one-by building. The structural story stiffness are kı-k₂-1x106 N/m, the floor masses are m₁= m2-1000 kg, the story height is 3 m both stories. This building located in a zone of site category of II, and the damping ratio of the two modes are all 0.05, the fortification intensity is 7 (basis acceleration value equals to 0.15g), belongs to the 2nd group. Answer the following questions. (a) Use the modal decomposition-based method to carry out the structural design. Please calculate the designed base shear and the inter-story drift ratio of the 1st story. The circular frequencies and mode shape vectors of the structure are given as following, (The corresponding tables from the Seismic Design Code is given in the Appendix) (b) Use the modal effective mass to explain why the design base shear of structure is dominated the 1st modal response.
