Abstract
¡¡¡¡The project is the Hotel of Shen Yang JiaHe which located in the DongLing district of Shenyang city. The seismic of fortification intensity of this building is grade 7. The design reference period is fifty years. The reference snow pressure is 0.4kN/m2 and the reference wind pressure is 0.50kN/m2
¡¡¡¡The areas covered by this engineering are 1800 square meters which own five stores. The total building areas are 6800 square meters. The height of the first stores is 4.2m and the others are 3.9m.Total height is 21.9 meters. The elevation of indoor ground is higher than the outside for 0.45m.The height of parapet is 0.9m.The thickness of the outside wall is 300mm and the inner wall is 160mm.The lightweight inner wall is 86mm.The shape of the building plan is rectangle. The total length is 63.3m and total width is 21.95m.The outward form of building is formal. The outside wall is decorated with marble. The middle front door is glass door and the others are solid wood doors. All the windows are plastic-steel windows.
¡¡¡¡The structural form of this engineering is steel frame with bracing. All columns are HW profiled bar .The cross sections of the first layer side-column are 3503001219,both second and third's are 3003001015 ,the forth and fifth's are 3002501012. The cross section of the first layer middle-column are 3943981118 ,the second and third's 3503501219,the forth and fifth's are 3503001219.All beams are HM profiled bar .The cross sections of the 6m spans are 340250914 and the 9m spans' are 4403001118.For the soil condition of the building site is good, so the foundation of column is independent foundation under column with the concrete of C25 for every column. The bracings that made of double angle irons are mounted in the portrait frames and the bracing angle irons are connected with frames by welding line.
¡¡¡¡The design strictly complied with the currently used code of our country. The calculation includes the calculation of the load, the composition of internal forces. the design and checking computations of the foundation ,the strength and the overall stability of the columns and beams , the calculation of stairs. In the
¡¡¡¡Keyword: Steel frame with bracing, Independent foundation, Bracing Reinforced concrete, Overall stability
