中学学生宿舍楼施工组织设计

中学学生宿舍楼施工组织设计摘要：本设计为中学学生宿舍楼施工组织设计，本设计场地尺寸为50m×20m。用地地形平缓，无不利地质情况，无软弱下卧层，地质情况良好。浙江金华市区地抗震设防烈度为6度，设计基本地震加速度为0.05g,采用钢筋混凝土框架结构，设计使用年限为50年。根据设计要求和功能需求初步进行了设计，主要查阅了《宿舍建筑设计规范》与《建筑结构荷载规范》等相关规范。结构设计部分主要对结构方案中⑥轴框架进行计算，并严格按照结构规范进行设计。设计内容主要包括以下几点：首先，进行结构选型，梁、柱、墙等构件尺寸的确定：然后计算层间荷载代表值：竖向荷载作用下框架内力计算采用弯矩二次分配法进行内力计算：利用D值法进行水平荷载的内力计算，将求得的内力进行内力组合，判断最不利组合进行构件计算，进而求得截面配筋。最后根据地质情况进行混凝土现浇基础的设计：此外还有楼梯、楼板、雨篷的配筋设计。关键词：学生宿舍：框架结构：钢筋混凝土：结构设计：内力组合Construction organization design ofdormitory building for middle schoolstudentsAbstract:Abstract:This design is the construction organization design of middle schoolstudents'dormitory.The design site size is 50mX 20m.The terrain of the land is gentle,withno unfavorable geological conditions and no soft substratum,and the geological conditionsare good.The seismic fortification intensity of Jinhua City,Zhejiang Province is 6 degrees,the design basic seismic acceleration is 0.05g,and the reinforced concrete frame structure isadopted,and the design service life is 50 years.According to the design requirements and functional requirements,the preliminarydesign was carried out,and the relevant specifications such as "Code for Design of DormitoryBuildings"and "Code for Load of Building Structures"were mainly consulted.The structuraldesign part mainly calculates the 6-axis frame in the structural scheme and designs it instrict accordance with the structural specifications.The design content mainly includes thefollowing points:firstly,the structural selection and the size determination of beams,columns,walls and other components are carried out;Then calculate the representative value ofinterlayer load;The internal force of the frame under vertical load is calculated by thesecondary distribution method of bending moment;The internal force of horizontal load iscalculated by D-value method,and the internal force obtained is combined,and the mostunfavorable combination is judged to calculate the components,and then the sectionreinforcement is obtained.Finally,the cast-in-place concrete foundation is designed accordingto the geological conditions;In addition,there are reinforcement design of stairs,floors andawningsKeywords:student dormitory;Frame structure;Reinforced concrete;Structural design;Internal force combination目录第1章工程设计基本资料及说明1.1工程概况…1.2建筑设计第2章结构选型及布置.3第3章荷载计算.73.1恒载计算.73.2荷载传递.093.3活戰计算.444442第4章竖向荷载作用下内力计算.15第5章横向水平荷载作用下框架的内力计算.32第6章内力组合。.386.1截面配筋设计.436.2框架梁截面设计44第7章现浇板截面设计…50第8章雨篷设计.54致谢.58参考文献.…59第1章工程设计基本资料及说明1.1工程概况项目名称中学学生宿舍楼施工组织设计校区内含有综合教学楼、食堂、风雨操场等，本设计为浙江金华技项目地点工学校学生宿舍楼，场地尺寸为50m*20m。总建筑面积不低于2500m最高气温39℃最低气温-5℃结构形式钢筋砼框架结构结构安全等级二级砼结构环境类别一类设计使用年限50年全年主导风向为东北风，夏季为西南风：根据《建筑结构荷载规范》气候条件(GB50009-2012)附表，南昌地区50年一遇基本风压为0.45kN/m2,拟建场地地面粗糙度为c类，50年一遇雪压为0.5kN/m2。根据《建筑抗震设计规范》(GB50011-2010,2016局部修订)南昌场地地震效应市区的抗震设防烈度为6度，设计基本地震加速度为0.05g,设计地震分组为第一组：拟建场地属Ⅱ类建筑场地：结构抗震设防类别为丙类；地基基础设计等级为丙级。地质水文情况用地地形平缓，无不利地质情况，无软弱下卧层。不考虑地下水作用。地层主要物理力学性能指标、物理状态和容许承载力值见表1。表1.建筑地层一览表（标准值）序号岩土分类土层厚度(m)平均厚度(m)地基承载力(kpa)杂填土0-0.80.82粉质黏土0.8-5.64.62403砾砂层5.6-7.51.93151.2建筑设计总平
