某学校多层框架结构工程设计 摘 要：本设计为某学校多层框架结构工程，主体结构为七层框架结构。总建筑面积约为6700平米。建筑总高度为25.8m。 本设计包括建筑设计和结构设计两部分，建筑部分包括平、立、剖面的设计，以及部分构造做法的确定等。结构部分有结构体系体系的布置、基本构件截面尺寸的确定。结构的刚度计算、内力的不利组合。除此之外，利用结构设计软件PKPM 进行一榀框架的截面设计、一榀框架的内力配筋的计算、现浇楼板设计、现浇楼梯设计，基础的设计，并对主要控制截面的内力与手算进行比较分析。 关 键 词：框架结构；结构设计；内力组合；抗震；防火 Underground garage and the air defense project construction quality control of water Abstract：This project is the army office building of Tuoketuo County in Inner Mongolia. The project main body is 7-storyframe structure system. The total architectural area of the building is about 6700m2,with a higth of30.3m. The whole design consists of two parts which is the architecture design and the structure design. Architecture design includes horizontal design、vertical design、profile design as well as parts of determination of structure and construction and so on. The structure design contains the arrangement of the structure system , the section size determination of the basic members, the computation of the structure rigidity, the computation of internal force and reinforcement of a frame, the disadvantageous combination of the internal force, the cast-in-situ floor design,the staircase design, the independent foundation design and so on.In addition, useing the structure program of PKPM for the section design of a frame, and then,comparing the primary control sections internal force with the hand calculation . The fortifier intensity is octave, the grade of fireproof is second class. According to the fire protection and the earthquake resistance request, this structural arrangement is a shape, the main body floor set two staircases. Key word: frame construction; earthquake resistance; fire protection; structural design; endogenic force compound 目 录 1 工程概况与设计资料 1 1.1工程概况 1 1.2设计资料 1 2 结构体系的选择与结构布置 1 2.1结构体系 1 2.2结构布置 2 2.2.1抗震设计的基本原则 2 2.2.2结构平面布置原则 3 2.2.3结构竖向布置原则 3 2.3 框架结构的承重方案 3 2.4抗震等级 3 2.5 结构总体布置 3 3 构件截面尺寸初选 4 3.1框架梁尺寸初选 4 3.2柱截面尺寸确定 5 3.3板截面尺寸的选定 6 4 材料选取 6 5 重力荷载计算 7 5.1
