框架--剪力墙结构,也称为框剪结构,广泛应用于办公和公用高层建筑,也大量应用于高层旅馆设计,我的毕业设计是框架--剪力墙结构的高层办公楼设计。这种结构由框架梁柱形成自由灵活的空间,容易满足建筑功能的要求;同时又有一定数量的剪力墙,使得它具有很强的抗震能力,同时,剪力墙的设置,减少了在水平荷载作用下结构的侧移,避免砌体填充墙在地震中严重破坏和倒塌。所以,在地震区要采用框架结构时,宜优先选用框剪结构。四川汶川的大地震,损失严重,更能说明将结构做的完美的重要性。
我的设计内容主要是结构设计,毕业设计是土木工程专业的必修课程,我的设计是办公楼设计,设计采用钢筋混凝土现浇框架--剪力墙结构,建筑层数为十一层,地上十层,地下一层,建筑总高度39.9 m,总建筑面积10174.32㎡,其中地下室占地面积为1017.47㎡。根据设计要求,设防烈度为7度,抗震等级为二级,设计中要考虑抗震设计。设计包括结构部分、楼梯、基础等。根据任务书定出各层平面图及平面布置。本方案主体结构为双向承重框架—剪力墙结构。在进行荷载计算和构件截面估算后,选取了一榀框架—剪力墙进行计算,计算内容包括框架梁、框架柱、剪力墙、连梁的截面尺寸的选取及线刚度的计算;恒载、活载、地震作用下梁端、柱端、剪力墙、连梁的弯矩、剪力的计算;框架、剪力墙、连梁的内力组合;框架梁柱配筋计算;楼梯配筋计算及基础设计。框架受力钢筋主要采用Ⅲ级钢筋,箍筋主要采用Ⅰ级钢筋,楼梯采用钢筋混凝土梁板式楼梯;由于上部结构荷载较大,地基土存在软弱层,基础采用钢筋混凝土筏板基础。整个方案设计基本符合设计和结构要求,具有一定的合理性。
通过对办公楼楼层平面图、剖面图、构造图的绘制和结构的设计,熟悉了设计的全过程,并能熟练应用AuToCAD、天正绘图软件等,并熟悉了一下PKPM的应用,掌握了结构设计计算的基本方法,创造性的完成了毕业设计任务。同时,对大学所学的专业知识和基本概念有了更深的理解,从而提高了分析和解决实际问题的能力。

Abstract:
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.
