Structural Optimization Design of a Tall Residential Building with Rectangle Layout in High Seismic Intensity

The principle of structure optimal design for high building with shear wall structure is introduced in detail. Six structure schemes of a residential building with rectangle plane in high seismic intensity are proposed. Then six structural models are set up and calculated by SATWE software. And parameters of the result, such as story lateral stiffness and ratio of stiffness of the story to the upper story, inter-story displacement ratio, story seismic shear and so on are analyzed respectively. By controlling the displacement and lateral stiffness to a rational value and the material amount to a minimum level, the six structure schemes are compared and an optimal one is selected.
