Framework - shear wall structure, also known as FRAME-SHEAR WALL structure, widely used in public office and high-rise building, also used in large high-rise hotel design, and mine is in this type.The type of this structure is flexible in space, and the building is easy to meet the demands ,and also a certain amount of shear walls, making it a strong earthquake capacity, while the shear wall set up, reducing the Level load structure under the sway, to avoid filling masonry wall in the quake severely damaged and collapsed. Therefore, in the earthquake zone to adopt the framework of the structure, to give priority optional FRAME-SHEAR WALL structure. Chuan Wenchuan four of the last major earthquake, serious damage, the structure will be better able to explain the importance of doing perfect.
I design the content is mainly structural design, civil engineering graduate design is a compulsory course, my office building design is design, design a framework of cast-in-place reinforced concrete - shear wall structure, building a 10 storeys to the ground 10 layer, a layer of the ground floor, building height of 39.9 m, a total construction area of 10174.32 square meters, which covers an area of the basement to 1017.47 square meters. According to the design requirements, the intensity of seven degree of security, seismic rating for the two, to consider the design of seismic design. Including the design of the structure of the stairs, the foundation. According to the mandate set of floor plans and layout of each floor. The programme for the two-way load-bearing structure of the main framework - shear wall structure. Load component in the calculation and estimates section, select a Pin framework - a shear wall, the calculation includes the framework of beams, columns, shear walls, even the size of the beam section and select the stiffness of the calculation; constant load , The live load, under earthquake Beam, column-, shear walls, and even beam the moment, shear the calculation; framework, shear walls, beam combination of internal forces; framework reinforced beams calculated reinforced staircases The basis of calculation and design. The framework of reinforced steel bars used mainly Ⅲ level, the main use of stirrups Ⅰ-class steel, reinforced concrete beams using the stairs plate staircase; larger load because of the upper structure, the existence of weak foundation soil layer, based on a reinforced concrete raft foundation. The basic design of the entire programme with the design and structural requirements, have a certain reasonable.
Through the office building floor plans, profiles, construction and structure of the plan is drawing the design, familiar with the design of the entire process, and can skillfully use AuToCAD, Tianzheng mapping software, and familiar with the application of the PKPM, mastered the structural design calculations The basic method, the completion of the graduate creative design task. At the same time, the study by the University of the basic concepts and expertise gained a deeper understanding, so as to enhance the analysis and the ability to solve practical problems.
