It consists of five stories, high. The first story is high, and the others stories are high. Architectural part: According to its geography situation and all requisite functions and others conditions, we carry out architecture about the plane layout, vertical plane and vertical sections, etc. At this time, we try our best to make the building beautiful, economical and useful. In the design of overall planning , ask and afforest as far as place is concerned the influence of facility, other function requirement and as well as around building, adopt design “ L” type. Structural part: The structure form is a frame structure, all of the columns, beams, and slabs are castinsite. Foundations are independent foundations under columns, and we finish the drawing of the structural design for the next construction at last. The calculate book primarily includes eight parts: The construction are choosed by the type, the level frame construction that dint function bottom putes, the frame that ecocentic load function the bottom dint is inside the calculation, horizontal frame dint bination, cut the size the design, knothole the design, foundation the design, stairs the design and as well as drawings are pleted in the end. Key word: Frame structure。畢業(yè)設(shè)計(jì) 1 目錄 摘要 .....................................................................................................................................
