五层办公楼全现浇混凝土框架结构计算书.doc

摘 要 本工程名称为某，结构为全现浇混凝土框架结构，层。工程所在地区为，抗震设防等级为度。抗震结构在地震作用下，为了有良好的耗能能力以及在强震下结构不倒塌，其构件应有足够的延性。要设计延性框架结构，需满足“强柱弱梁，强剪弱弯，强节点弱构件”的要求，并进行相应的内力调整，然后由调整后的内力值进行配筋计算。 本次设计主要包括结构选型及结构布置、确定计算简图及计算单元、荷载计算、侧移控制、内力组合、构件设计、楼梯设计、基础设计等内容 。本工程采用钢筋混凝土结构框架结构体系（横向承重），选择了有代表性的一榀框架进行计算。对于竖向荷载作用采用弯矩二次分配法，水平荷载作用采用法。设计计算整个过程中综合考虑了技术经济指标和施工工业化的要求  ABSTRACT This project is designed for office building use with a style of cast-in frame work. The building has five floors.the structure locates JiNan with an anti-earthquake degree of 6. The design process follows the order: firstly, the architectural design; secondly, the structural design; lastly, the foundation design. The architectural design, according to the master plan of the building, the site conditions, peripheral urban environment, and characteristic of the base, the building plain design goes first. The elevation design is carried out secondly. Considering the building classification and fire prevention demands. The architectural design should meet the needs of the function requirement, the use requirement and development and flexible transformation in the future. In order to prevent the building from collapsing, we must insure the inducity of the members.The structure needs to meet the demand of “strong columns with weak beams, strong anti-shear to weak anti-bending, strong joints with weak members”,.The calculation goes under the adjusted inner stress values . . Structural design maintains close ties with the architectural design, which is based on current relevant codes. It includes the structure style, the preliminary estimation for the structural members, confirmation of the sketch and unit for calculation, sideway control, load calculation, component design, slab-stairs design, floor overlay design and foundation design. This project adopts reinforced concrete frame (transverse bearing), which has chosen a representative frame to calculate. Vertical load function adopts moment distribution method, level load function adopts D val
