Based On The Conceptual Design Of The Box - Cut Structural Economic Analysis

In the recent ten years frame and sheer-walls by its widespread serviceability and good earthquake resistance performance, is applied in world each place, especially obtained the massive applications in our country's high-rise construction. The existing literature to high-level aspects and so on structure principle of design, computational method and structure measure all has the detailed elaboration, the people are studying the frame and sheer-walls continuously the stress characteristic. The frame and sheer-walls anti-side rigidity to have the very tremendous influence to the structure earthquake resistance performance, the structure should design some to soften some just, because designed personnel's view not one, design result also entirely different, therefore, the corresponding structure economic indicator difference very was also big. On the other hand, each kind of design software which develops along with the computer science rapid development is widely used, the structure plan preliminary design level is affecting the design quality directly. At the same time, because the structure computation major part completes by the computer, easy to create the structure designer to the structure concept desalination. In view of the fact that above consideration, this article thought has the essential introduction to embark from the structure macroscopic whole, to focus on the structure whole response conceptual design mentality, carries on frame and sheer-walls concept optimization design research take the efficient analysis as the goal.The high-rise construction structure concept optimization design should include three levels: One, construction structure regularity; Two is the reasonable construction structure system choice; Three is the anti-lateral force structure and the component ductility design.The present paper union frame and sheer-walls example, deliberated the structure system conceptual design and the whole optimization method. Through establishes the frame and sheer-walls joint operation the differential equation and the solution, obtains the frame and sheer-walls to move the curve under the delta load function side, the bending moment, the shearing force distribution curve, after the analysis contrast, obtains the and sheer-walls best rigidity characteristic value sector.The present paper utilizes "Multi-layered And High-rise construction Structure Space Finite element Design Analysis Software SATWE" takes the computation analysis the auxiliary means. May know from the computed result analysis: Along with various part of component size and the structure rigidity characteristic value change, the horizontal earthquake function is also changing, thus causes the frame and sheer-walls the endogenic force change, causes the structure various components to match the muscle quantity, the concrete resilience and so on with the construction cost close correlation factor change, the cause structure total construction cost changes. Through to the total construction cost curve, the construction cost equivalent curve, each item of material construction cost curve, the construction cost constraint curve analysis, obtains between the structure characteristic and the project construction cost reciprocity, the analysis most low production cost existence possibility. Will pass through the portal frame and sheer-walls best rigidity characteristic value sector from the structure efficient angle union constraint condition which the stress analysis will obtain further to subdivide.The present paper has made the beneficial exploration in the structural design optimization and the project construction cost control union aspect, intends to offers a few ordinary introductory remarks so that others may offer their valuable ideas, to urge structural engineer to transform the idea, takes the project construction cost in the design stage the active control.
