多层办公综楼设计.doc

摘 要 设计的内容为建筑设计部分和结构设计部分。毕业设计是土木工程专业的必修课程，我的设计是多层办公综合楼，设计采用钢筋混凝土现浇框架结构，建筑层数为五层，建筑总高度24.4m。根据设计要求，设防烈度为7度，抗震等级为三级，设计中要考虑抗震设计。设计包括结构部分、基础等。根据任务书定出平面布置。本方案主体结构为双向承重框架，横向框架等跨。在进行荷载计算和构件截面估算后，选取了一榀框架进行计算，计算内容包括框架梁柱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、柱端弯矩、剪力的计算；框架内力组合；框架梁柱配筋计算；楼梯配筋计算及基础配筋计算。框架受力钢筋主要采用Ⅱ级钢筋，箍筋主要采用Ⅰ级钢筋.基础采用钢筋混凝土柱下独立基础。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。 通过对多层办公综合楼楼层平面图、剖面图、构造图的绘制和结构的设计，熟悉了设计的全过程，掌握了结构设计计算的基本方法，圆满地完成了毕业设计任务。对这些年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。 关键词：框架结构 板的设计 荷载计算 内力计算 内力组合 配筋设计 基础设计 Abstract The content of the design for architectural design and structural design. Graduation design is the civil engineering specialized compulsory course, is I the design of the city scenic area planned near the reservoir management committee office complex building, the design adopts the cast-in-place reinforced concrete frame structure, architectural layers for five layer, building a total height of 24.4 m. According to the design requirements, fortification intensity is 7 degrees, earthquake resistant level for level 3, want to consider in the design of earthquake resistant design. Design including the structural part, foundation, etc. According to the specification set layout. This scheme is the main structure is a two-way bearing frame, horizontal framework, etc. After load calculation and the estimated component cross section, select a common framework for the calculation, selection of calculation include frame beam section size and the calculation of the line rigidity; Under the action of dead load, live load, seismic beam end and column end bending moment, shearing force calculation; Frame internal force combination; Beam-column reinforcement calculation; The stairs foundation reinforcement calculation and reinforcement calculation. Frame reinforced mainly adopts Ⅱ reinforcing steel bar, stirrup mainly adopts reinforced Ⅰ level. Base adopts reinforced concrete independent foundation under column. The whole scheme design basic conform to the requirements of
