Research And Explore On Overall Conceptual Design Witch Especially For Special Shape Concrete Structure Of Tall Building

Proceeding from the rationality of design, general requirements for high-rise building structure should have a flat vertical size rules simple, basic symmetry of structures layout, lateral rigidity plane up and down vertical uniform and continuous. But in the actual engineering in the, design programme often be many subjective and objective conditions restricting, such as:site conditions limit (block with the red line and the space range limit), building outside type and the plastic arts requirements (landmark building such as CCTV building), programme congenital defects (in programme design stage structure engineer no in time participate in to programme developed in the), building function layout need (at the bottom of mall big space the upper residential, and device process related professional requirements) such as, many factors are lead to alien super limited senior appear. This type of special-shaped high-rise building there is a significant earthquake, and design difficult, spending long hours.In the process of design practice, we found that the usual design thinking and design methods have been unable to meet such high level. And the overall conceptual design gradually reflecting their superiority, using the concept of the overall concept can be handled well and finished the design of such structures. That is why, in recent years, raised the overall conceptual design method and its application more attention and rapid development.This article will combine actual works previously completed a complex building:Z shaped shaped structure of frame-shear wall structure) Design case, a summary of the overall conceptual design for special-shaped out-of-codes high-rise ways and main content of this article:1, an overview of the overall conceptual design method and calculation method of classification of complex tall and usually design,2, senior engineering for complex types with characteristics, classification structure design unit, determine the overall structure of the building system 3, an analysis of provisions related to overrun, come up with solutions to overrun provision, proposed a preliminary deal with the overall design of the layout plan, and trial calculation of the overall construction, building design the framework of the Programme4, through optimization of structure construction, make the structure more economic and reasonable system.5, design of large elastic-plastic performance under the epicenter of the earthquake...
