摘 要

钢筋混凝土框架结构设计是土木工程专业毕业设计的主要内容，钢筋混凝土框架结构设计主要包括建筑设计阶段和结构设计阶段。建筑设计，是根据任务书给定的功能和基础资料，确定建筑物的基本平面布局和平面的布置，再结合建筑使用风格确定建筑的外立面以及造型。

结构设计，是按照建筑施工图中的平面功能布置以及外立面，结合地质情况，对整个建筑进行深层分析和概念设计、结构选型与结构布置、结构荷载统计与计算、结构内力计算与组合、结构构件设计和验算等，设计出满足建筑结构安全、适用、经济性和耐久性要求的建筑结构的过程。结合建筑功能，本工程选择框架结构体系，平面采用梁板式结构，选取规则位置的一榀框架进行内力分析。按照结构布置，估算梁板柱尺寸，并计算梁和板的刚度；然后对竖向荷载进行计算，根据楼面做法以及墙体做法，计算出恒荷载和活荷载的标准值；在对水平荷载记性计算，计算风荷载和地震荷载作用下的标准值。利用一品框架的相对线刚度，对竖向荷载使用弯矩二次分配法计算一榀框架的内力，对水平荷载采用D值法计算一品框架的构件内力。按照现行荷载规范以及可靠度设计规范，将计算的各种工况下的内力标准值进行组合，并按规范进行塑性内力重分布调整，求解出构件计算的内力设计值，再对柱进行压弯构件箍筋和纵向受力钢筋计算，对梁进行受弯构件的箍筋和纵向受力钢筋计算。在构件设计部分，本设计对楼梯的平台板、梯段板和平台梁进行计算设计；对楼板进行了配筋设计；对基础进行承载力验算、冲切验算以及配筋设计。

在设计过程中，采用AutoCad和PKPM软件进行辅助设计，设计依据采用任务书指定的规范以及现行国家的其他相关规范，最终实现了框架结构的设计计算。

Summary

The main content of graduation design of civil engineering major is the design of reinforced concrete frame structure . The design of reinforced concrete frame structure mainly includes the stage of architectural design and the stage of structural design. Architectural design is the function and foundation data given in the task book to determine the basic layout and layout of the building according , and then to determine the exterior facade and shape of the building in combination with the architectural use style.

Structural design, according to the layout of the plane function and the outer facade in the construction drawing, combined with the geological conditions, carries on the deep analysis and the conceptual design to the whole building, the structure selection and the structure arrangement, the structure load statistics and the calculation, the structure internal force calculation and the combination, the structure member design and the checking calculation, designs the construction structure which satisfies the building structure safety, the application, the economy and the durability request process. Combined with the building function, this project selects the frame structure system, the plane adopts the beam-slab type structure, selects the regular position one frame to carry on the internal force analysis. According to the structure arrangement, the size of beam, slab and column is estimated, and the stiffness of beam and slab is calculated; then the vertical load is calculated, and the standard value of constant load and live load is calculated according to the practice of floor and wall, and the standard value under the action of wind load and earthquake load is calculated by calculating the recording of horizontal load. Based on the relative linear stiffness of a frame, the internal force of a frame is calculated by using the secondary distribution method of bending moment for vertical load, and the internal force of a frame is calculated by D value method for horizontal load. According to the current load code and reliability design code, the internal force standard values under various working conditions are combined, and the plastic internal force redistribution adjustment is carried out according to the code to solve the internal force design values calculated by the members, and then the columns are calculated by the stirrups and longitudinal stress bars of the compression and bending members, and the stirrups and longitudinal stress bars of the beams are calculated. In the component design part, this design carries on the calculation design to the stair platform board, the ladder section board and the platform beam; has carried on the reinforcement design to the floor; has carried on the bearing capacity check, the punching check calculation and the reinforcement design to the foundation.

AutoCad and PKPM software are used in the design process, and the design is based on the specifications specified in the taskbook and other relevant national codes.
