[Abstract]:The high plane hangar is a special type of aircraft hangar which adapts the conventional aircraft hangar to the situation of the airport topography in the high filling area. By placing the hangar at the second or higher level of the building, it is of positive significance to reduce the earthwork filling, reduce the engineering cost, increase the effective use area of the building, provide the land use efficiency and reduce the environmental damage. In this paper, the arrangement of anti-lateral force system of high plane hangar and its response under earthquake are studied, and the difference between the arrangement of anti-lateral force system and that of conventional hangar is analyzed and compared. The main points and contents of the design of the anti-lateral force system of the high plane hangar are put forward. The main contents of this paper are as follows: 1. The characteristics of high plane hangar are studied and analyzed, and the principle of anti-lateral force system arrangement of high plane hangar is discussed. This paper puts forward the layout method and design features of the anti-lateral force components of the high plane hangar, and compares the setting requirements of the anti-lateral force system with that of the conventional hangar, and puts forward the research model of the high-position aircraft hangar in this paper. The elastic analysis of the anti-lateral force system of high plane hangar under the action of frequent earthquake is mainly studied, and the structural response under the action of frequent earthquake is studied, and the mode decomposition response spectrum analysis and mode decomposition time history analysis are carried out. Combined with the static analysis results under the representative gravity load, the structural responses of the base shear force distribution and the maximum displacement of each layer of the high plane hangar under the action of frequent earthquakes are analyzed, and the characteristics of the vibration modes are analyzed. The elastoplastic static and dynamic time history analysis of high plane hangar under rare earthquake is carried out. The analysis shows that the concrete structural members of the hangar and the lower layer of the hangar have entered the elastic-plastic stage under the rare earthquake, and the elastic-plastic time history of the structure under the rare earthquake is analyzed. The structural responses such as the base shear force and the maximum displacement of the column top of the high plane hangar under rare earthquakes are obtained, and the appearance, distribution and development of the weak part of the structure and the plastic hinge are analyzed. The optimum design of the structure has a great influence on the cost. In this paper, the maximum bending moment of the primary and secondary beams under the actual aircraft wheel compression and the unit uniform load is simulated by the finite element software, and the different beam-plate arrangement is obtained. At the same time, the average load reduction coefficient of the main and secondary beams is obtained, and the applicability of these results is analyzed, and some suggestions for use are given.
