Design Result

Using the conventional structural design methods, the design result is usually not the most economical and the most reasonable. While, using the single target structural optimization design method, duo to the only one target function to be optimized, the design result often can not meet with the multiple requirements of structural designing, furthermore its optimizing efficiency is low. So its application is limited. This paper proposes multi-target earthquake-resistant optimization design method for reinforced concrete frame structure under earthquake loading. In the optimization design approach, the ductility and cost which are two factors contradictory each other in structure designing are simultaneously taken as the target functions, and the function relation formula between them has been established, giving simultaneous consideration to the structural economy, safety and practicability. Using this design approach, the optimum cross-sectional dimensions, with the largest ductility and the lowest cost, of the reinforced concrete frame structure which is optimized under earthquake loading, can be obtained by computer. The practical examples of structure design, which have been optimized by using this approach, show that the cost of construction has been cut down by about 10% comparing with the conventional designing. The optimization process presented in this paper conforms entirely to the China national standards: “Code for Design of Reinforced Concrete Structures” (GB50010-2002) and “Code for Earthquake-resistant Design of Buildings” (GB50011). The theory and methods presented in this paper, having not only their theory meanings but their practical values, will be helpful for the structural design engineers and the researchers.

Isolation Device

The multi-storey reinforced concrete frame structure used lead rubber pad as the base isolation device. The paper had modal analysis of base-isolated multi-storey reinforced concrete frame structure using the ANSYS software. Comparing the frequency and vibration mode before and after isolation under El-Centro wave, It concluded the leader rubber pad have seismic isolation effect for multi-storey reinforced concrete frame structure .

Reinforced Concrete Frame Structure

Taking a 5-story reinforced concrete frame structure on the transformed 3-layer steel frames for an example, use finite element software ANSYS to reformation as a whole building model under static wind load changes for comparative analysis of internal force and displacement of the corresponding node. Analysis results show that in the transformation of steel on reinforced concrete frame structure, should fully take into account the structural stiffness change on construction of the overall effect of wind resistance, so that the transformation of the steel concrete frame structure more reasonable.
