High-rise Buildings Systematic Structure Of The Conceptual Design Study

With the development of the economy,the high-rise buildings' outline,structure pattern and so on have great changes.To the young designers,it's not easy to get a reasonable scheme especially they have not much experience.Whatsmore;currently many structure designers pay more attention to the buildings' safety and the structure self and they neglect the economic benefits.Therefore,the problem to be sloved in dire need of is how to make the design more safety,more economically and more effectively.The method of conceptual design of building structure,as a new method of thinking,it tries to slove the above problem.However, now it's still be studied and discussed.In this thesis,it used the method of conceptual design and combined the systematization thinking at the stage of primary structure design of high-rise buildings.It took the building as a whole to have a synthetical study.That was,at the stage of primary structure design,it not only considered the structure but also the architecture,equipments,energy sources,the cost of land,the building's geographical position and so on.And it also considered the current and subsequent factors.It established a decision-making model of systematization conceptual design of structure.The results realize primary integration of many different designers and design phases.To solve the decision-making model,It took a new algorithm-random weighting of multiobjective genetic algorithm.According to its basic ideology,a program with MATLAB 6.5 was written.With this method,it gets many Pareto set-many primary schemes,the designers can chose the best fit sheme with different requests.Because of one of the main results solving the model is that the main structure pattern of high-rise office buildings is reinforced concrete frame-shear wall or frame-tube structure,therefore,it studied the conceptual design of frame-shear wall structure especially,and provided the method and approach to optimize the conceptual design.It applied the method which primarily ascertains the amounts of shear walls to idiographic example.The results proves the method is convenient and effective.Whatsmore;it provided the ways to estimate the reasonable computing results of computers.The engineering designers can make good use of all of these.
