From the basic theory of structural optimization design and shape control factors, the characteristics and control requirements for control factors of high-rise frame shear wall structure optimization have been introduced in this paper. The research and analysis showed that: the structure system and building height, length-width ratio of building plane, and the vertical height-width ratio play an important role on structural optimization.

The couple shear wall structures are well known for their anti-lateral stability, they have a promising future in macro complex high-level structures. Coupling beam dampers are the key components of coupled shear wall structures. In this manuscript, metallic in plane yield coupling beam damper with four types of poration and different pore areas are analyzed by Finite Element Method. It is found that the hourglass-shaped poring coupling beam damper has superior hysteretic behavior and higher carrying capacity comparing to other types of poring damper. In addition, the optimized poration parameters are further obtained by using Kriging surrogate model, which maximize the carrying capacity and enhance hysteretic behavior of the hourglass-shaped coupling beam damper.

The Cost

Failure-mode based optimization is very effective at improving the performance of structure, therefore, a new optimal approach based on failure mode with the ability to limit the cost is proposed. Three different failure modes of the coupled wall are discussed, and then the objective function is setted up according to the expected failure mode and minimum cost. Finally, an example is cited to verify the method. It is concluded that the method can supply an effective way to reduce the cost of coupled shear wall, and the expected failure mode can be obtained.

Optimization design is the significant development in the structure design which could adopt the better from several plans in the same task. This paper build the finite element model of sixteen-floors shear wall structures, which control the deformation as the restraint condition, to make the thickness of shear wall as the design variable and to take the light structure as the objective function in order to execute the optimization. After the optimization, the bottom and internal stress become higher, whereas the centralized stress will occur in the corner and the middle of the rooftop and the opening of the shear wall. The horizontal earthquake of the various floors presents the curve like S with the increasing of the floors. And the floor which occur earthquake effect and the biggest displacement angle is in the middle of the structure and the whip tip effect will emerge in the top of the structure.

Predictive Method

With the rapid development of high-rise shear-wall structure residence buildings in domestic large and medium-sized cities, it brings the problem that traditional structural design wastes materials, which is now taken seriously. Structural optimization design can save materials more than 10% in general. This paper carries structural optimization design on eight shear-wall structure residence buildings, and proposes a predictive method for concrete dosage of high-rise shear-wall structure residence buildings after analysis. The predictive method makes it easier to obtain the concrete dosage, because it frees from the cumbersome process of engineering budget. The predictive value is economical and reasonable, and it can be used to guide structural design.
