| Automobile industry has been one of the pillar industry. As a kind of the commercial building, the exhibition hall of automobile is a architecture vehicle of the sell network of the automobile and become to emerge more and more in the city construct recent years. For its own constitution of function, the exhibition halls of automobile are very different from the traditional steel constructs in scale of construction and appearance. Structure lectotype of the exhibition hall of automobile is key in whole design process, and is a critical factor during the structure exerting its structure capabilities. The exhibition halls of automobile have big spans so steel structure is adopted usually for it. However, at the present time the studies on the exhibition halls of automobile are short of in-depth researches and synthetical contrasts.Beginning with the development of the exhibition halls of automobile, this paper produces several sorts of typical structure forms and separately summarizes their structural function, structural behavior, economy and the feasibility of construction; Based on the exhibition hall of the car of Tianlong car-trade centre of Zhengzhou, this paper used three precept: Precept 1: steel ladder-type roof truss + steel pillars, analyzed by soft STS; Precept 2: gabled frames, analyzed by soft 3D3S; Precept 3: space latticed frame + steel pillars. Under all combinations of loads, the three precepts are analyzed and compared in the force and deformation, weight of steel, direct investment, available use area, time limit for the project and benefits. We can conclude that gabled frame is more suitable for the exhibition hall of the car.According to all summaries, calculation and contrast, this paper approached to how to select structure lectotype, and achieved some useful conclusions which may instruct the development and consummation of the exhibition hall of automobile. |
