碩士 === 國立成功大學 === 土木工程學系碩士在職專班 === 105 === In this study, the ETABS structural design and analysis software construction model was used to analyze the ultimate shear strength of three different Steel Moment Resistant Frame (SMRF) systems. In the meantime, the relative lateral displacement angle of the interlayer shall not exceed 0.005. The ETABS program is used to find the optimal amount of steel configuration, and it is then used to find the plastic bending moment of each section, indirectly obtained the column shear. The shear strength of each layer is taken as the shear strength of the layer, and then the seismic strength of each layer is calculated by comparing the seismic strength of the building. If the upper and lower limits of the shear strength of the lower layer meet the requirements, exist the procedure. In this thesis, we will understand the calculation principle and method of the application of Civil 404-100 Concrete Engineering Design Code (Volume II), and change the structure of the three common building structures on the market. After the displacement angle, the plastic bending moment of each column is obtained, the horizontal shear strength of each column is thus obtained indirectly. Then, the influence of seismic force on the weak structure of the building structure is obtained and discussed. For the structure of the weak layer, the reinforcement and improvement can be performed.
