The Structural Design Of High-rise Building And Structural Form Selection Research Of One Project

Optimum design of structure is mainly applied in airial structure nowadays, while rarely in engineering structure. After 1980s, with the GDP of our country increasing, it takes on a well structure building situation, especially the number of tall building leaps. But the conventional design of structure can't make use of material rationally, and can't increase the economic index of structure. Otherwise, our country is still in initial stages of socialism construction and economic strength is still in arrears.So optimum design of tall buiding is in the most urgent situation. But there are some imperfect aspects, which become the hindrance for engineers to accept this technigue.This paper points out that expert system is very available for optimum conceptual design,and introduces the model of decision of optimal fortification intensity,which brought forth by Wang Guangyuan academician,into the whole life optimization of structure,and convert the long-term optimum model into a shor-term one.Then author advances the continual optimum design to discrete optimum design,which meets engineering structures much better.After lucubration of discrete optimum design in common use, penman get some banausic conclusion.Based on the method of discrete optimum design,pertinent criterion and engineering experience,author builds up the models of optimum design of various kinds of tall buiding styles,and introduces a new structure anglysis mothld—Matrix Recursion Method, by which workload of analysis is much less than Finite Elements Method etc, into optimum design, increases the efficienty of optimum design very much.Although this dissertation gets conclusion with applied value based on the analysis of theories, as a study with much practicability, if the optimum design can be accepted by structures engineers, it must be expressed as a computer program with a friendly UI and efficient operational speed. Because of the shortage in studing and cognition, at the last of this paper, author makes a bold prospect about future study in these aspects.
