本设计方案主题结构为横向承重框架,计算时选用一榀框架为计算单元,根据各构件刚度计算出不同荷载作用下的结构内力,各内力组合后按照抗震要求分别进行调整,然后分别进行楼板,楼梯,框架梁、柱的配筋。框架结构设计的计算工作量很大,在计算过程中以手算为主,辅以一些计算软件的校正。由于水平有限,难免有不妥和疏忽之处,请各位老师批评指正。 设计计算书一、工程概况1.1、工程概况本工程为框架研发楼。建筑面积约为5000m2,结构形式为现浇钢筋混凝土框架结构,总层数为五层,无地下室。建筑耐火等级为二级,设计合理使用年限为50年。建筑结构安全等级为二级,三级框架,抗震设防烈度为7度,设计基本地震加速度值为0.10g;场地土II类,地基承载力fk=216kpa。1.2、建筑设计说明本毕业设计课题为研发楼的建筑与结构设计。建筑总面积为5000平方米左右,混凝土框架结构,主体五层。楼层内包括办公室,厕所,开水房,值班室以及休息室。1.2.1建筑设计原则设计全过程将充分考虑安全、经济、适用三要素,满足消防要求,采光通风良好,同时考虑到绿色低碳建筑在此次设计中的应用,建筑设计注意与周围环境的协调,功能区组合合理。考虑建筑自身特点,着力体现出现代化高校教学楼和谐自然、实用又美观大方的形象特点。方案应符合规范,满足功能要求,妥善处理建筑与结构关系。注明房间面积、功能和总建筑面积。1.2.2建筑设计教学楼的人员流动相对较大,基于消防的考虑,本工程采用一字型布局。整栋建筑采用内廊式的通道形式,内廊通道设计宽度为2.6m。底层有一个主入口,两个分入口,设有两个楼梯,能满足消防和交通要求。为了满足功能的需要,建筑布局以大开间为主,开间为8.2m,进深为8.2m。建筑层高均为2.9m。1.2.3建筑缩略图建筑缩略图如图1.2.3所示105 图1.2.3底层平面图105 二、结构布置结构设计根据建筑施工图确定结构方案。主梁沿横向布置,次梁沿纵向布置,划分板块,根据规范,由跨度确定梁板的截面尺寸;柱的截面尺寸由轴压比限值初步确定,也可假定一配筋率根据轴心受压柱来计算柱的截面尺寸。2.1结构设计与分析概述2.1.1上部结构的设计1)楼盖的设计:本设计选择标准层楼盖进行设计。按照荷载分析、内力计算及配筋的一般过程,设计楼板。2)框架的设计:选取4轴线所在框架进行设计。按照荷载分析、内力分析(包括恒载、活载和水平地震三种作用下的内力分析)、侧移分析和验算(由于多层框架结构的整体弯曲变形很小,故仅验算其整体剪切变形)、内力组合、截面设计的一般过程进行。其中:竖向荷载作用下的内力分析采用弯矩二次分配法;水平荷载作用下采用D值法。最后,进行电算校核,分析误差3)楼梯的设计:采用现浇板式楼梯。包括梯段板的设计、平台板的设计以及平台梁的设计。2.1.2设计内容本设计计算书包括标标准层楼板的设计计算;一榀框架的设计计算、楼梯的设计计算。计算方法及原理应满足结构设计规范标准。2.1.3设计准备工程所在地抗震设防烈度为7度,设计基本地震加速度为0.10g,设计地震分组为第一组,场地类别为Ⅱ类。屋面做法:防水等级为Ⅲ级,一道防水设防,使用年限10年。采用高聚物改性沥青卷材防水屋面。雪荷载标准值:0.30kN/m2(n=50年)2.2结构平面布置如图7.1,各梁柱截面尺寸确定如下:105

七、截面设计7.1框架梁的截面设计以第一层框架BC跨为例计算。弯矩以梁下部受拉为正;上部受拉为负。梁支座处,不考虑下部受拉钢筋在支座负弯矩作用下的受压作用,按单筋截面分别计算梁的上下部配筋。梁内纵筋采用HRB335,,混凝土采用C30,;;框架梁箍筋采用HPB300,1、正截面受弯承载力计算由弯矩组合表可得,第一层BC跨梁不利组合为:BC梁:右端:跨中:左端:(1)右端①在正弯矩作用下:保护层厚度,取,则。按T形截面设计,取100mm(现浇混凝土楼板板厚),翼缘宽度取,属第一类T形梁。105 选配425,实有As=1964mm2②在负弯矩作用下:保护层厚度,取,则。选配425,实有As=1964mm2验算三级框架抗震要求:,均满足要求。(2)跨中对跨中截面,梁下部受拉,考虑现浇楼板得翼缘作用,应按T形截面设计,取100mm(现浇混凝土楼板板厚),翼缘宽度取,属第一类T形梁。105 选配425,实有As=1963mm2,满足要求。(3最小、最大配筋率要求:a)最小配筋率根据规范三级框架,框架梁纵向受拉钢筋的最小配筋百分率:跨中:0.2和0.45ft/fy中的较大值;支座:0.25和0.55ft/fy中的较大值跨中:;支座:检验均满足要求。b)最大配筋率要求:根据规范,三级框架不应大于2.5%。经检验,均满足要求。7.2、梁斜截面承载力计算(1)斜截面计算过程见表7.1(2)斜截面受剪承载力验算:考虑在反复荷载作用下,混凝土斜截面强度有所降低,根据抗震规范,应乘以0.8的折减系数,所以斜截面受剪承载力以下式验算:105

结论通过毕业设计,我不仅温习了以前在课堂上学习的专业知识,同时我也得到了老师和同学的帮助,学习和体会到了建筑结构设计的基本技能和思想。特别值得一提的是,我深深的认识到作为一个结构工程师,应该具备一种严谨的设计态度,本着建筑以人为本的思想,力求做到实用、经济、美观;在设计一幢建筑物的过程中,应该严格按照建筑规范的要求,同时也要考虑各个工种的协调和合作,特别是结构和建筑的交流,结构设计和施工的协调。这就要求一个结构工程师应该具备灵活的一面,不仅要抓住建筑结构设计的主要矛盾,同时也要全面地考虑一些细节和局部的设计。在毕业设计的过程中,我深深地认识到各种建筑规范和规定是建筑设计的灵魂,一定要好好把握。在以后的学习和工作中,我会不断加强对建筑规范的学习和体会。有了这个根本,我们就不会犯工程上的低级错误,时我们在处理工程问题时就会有更大的灵活性,也会有自己的创新。在本次毕业设计中,我深深的感觉到了基础知识的重要性。在以前学习结构力学、钢筋混凝土结构、建筑结构抗震等专业课时,老是觉得所学的东西跟实际相差的太远,甚至觉得没什么用。这种急功近利的思想使自己对一些专业课的学习有所放松,在毕业设计的过程中,我感觉到那些基础知识是相当重要的。在以后的学习生活中切不可急于求成而忽略了基础的夯实,对一门系统的科学,应该扎实的学习它的每一部分知识,充分利用各种实践环节,切实做到理论联系实践,学以致用。如今,对于将要迈出学校大门的我,满怀希望和对未来的美好憧憬,决心不负众望,去开创属于自己的一片天地!105
