本科毕业设计 某科研办公楼框架结构设计 摘要 本设计层，总建筑面积约平方米。层高3.米。主体采用框架结构体系，填充墙采用混凝土砌块墙，基础采用独立基础。 Abstract The body of this design is a 5-story cultivating building, and the total floor area is about 5,467 square meters. The main height of the floor is 3.8 meters. The body uses the portal frame construction system, the packing wall uses the hollow clay block, and the foundation uses the pile foundation. The purpose of the designs is to make me farniliar with procedure and method of high-floor architectural designs, to master the whole process-from outline design, sophisticated design, to structural one. Strictly according to the sequence of practical design, architectural and structural designs are carried out wholy and detailedly. Contents of the design are as following: outline design for architecture bar disposal for every floor planks, floor beams and ceiling planks, internal force analysis by means of Layer Division for rows of a horizanfal frame and a longitudinal one affected by vertical load, internal force analysis and deformity’s checking computations by means of D-value for rows of a horizontal frame and a hngitudinal one affected by horizontal load, internal force composing: cross-sectional designs and joints designs for frame beams and columns and columns ,calculations and reinforcing bar disposal for stairs and basis. Lots of parameters are gathered by the form of tables. The consultation and use method of standards have been familiarized and preliminarily mastered. All the above-presented exposition could be used for reference in my future career. Keywords: Structural design; Analysis of internal forces; Checking deformation; Combination of internal forces 目 录 摘要 I Abstract II 第1章 绪论 1 1.1 课题背景 1 1.2 工程概况 1 1.3 设计资料 1 1.4 主要结构材料 2 1.5 设计内容 2 1.6 设计方法 2 第2章 结构布置及计算简图的确定 3 2.1 结构布置 3 2.2 确定梁柱截面尺寸 3 2.3 计算简图的确定 4 第3章 构件设计 5 3.1 楼板荷载 5 3.1.1 恒荷载计算 5 3.1.2 活荷载计算 5 3.2 楼板设计 6 3.2.1 设计资料 6 3.2.2 荷载设计值 7 3.2.3 计算跨度 7 3.2.4 弯矩计算 7 3.2.5 截面设计 9 3.3 次梁设计 11 3.3.1荷载（L-2） 11 3.3.2
