摘要随着经济的发展，商住楼以其优越的地理位置、且商且住灵活变通的物业功能、居家投资两相宜的营销理念在楼市中异军突起。商住楼不但具有写字楼所具有的一切优势，包括从产品上、服务上这些方面，也具有写字楼所没有的优势。用途上，商住楼可商可住，而纯写字楼只能商用；另外价格上，商住楼更有优势，它以比住宅稍高比写字楼更低的价格优势获得中小企业的青睐。本次毕业设计是商住楼，主要进行的是结构设计部分。结构设计简而言之就是用结构语言来表达工程师所要表达的东西。结构语言就是结构师从建筑及其它专业图纸中所提炼简化出来的结构元素，包括基础、墙、柱、梁、板、楼梯、大样细部图等等。然后用这些结构元素来构成建筑物或构筑物的结构体系，包括竖向和水平的承重及抗力体系，再把各种情况产生的荷载以最简洁的方式传递至基础。结构设计的阶段大体可以分为三个阶段： 一结构方案阶段：根据建筑的重要性，建筑所在地的抗震设防烈度，工程地质勘查报告，建筑场地的类别及建筑的高度和层数来确定建筑的结构形式，本工程采用的是框架结构；二结构计算阶段：包括荷载计算、内力计算和构件计算；三施工图设计阶段：根据上述计算结果，来最终确定构件布置和构件配筋以及根据规范的要求来确定结构构件的构造措施。关键词：商住楼；结构设计；荷载计算；节点验算ABSTRACTWiththedevelopmentofeconomy,commerce-residencebuildingemergesintherealestatemarketforitsadvantageouslocation,flexibledualfunctionsandthemarketingideaofbeingappropriateforbothhousingandinvestment.Ithasallthemeritsoftheofficebuildingintheaspectsofproductandservice,aswellasseveraladvantagesthattheofficebuidinglacks.First,itcanbeusedaseitherresidenceoroffice

按顶点位移法计算框架的自振周期顶点位移法是求结构基本频率的一种近似方法。将结构按质量分布情况简化为无限质点的悬臂直杆，导出以直杆顶点位移表示的基频公式。这样，只要求出结构的顶点水平位移，就可以按下式求得结构的基本周期：式中：——基本周期调整系数。考虑填充墙对框架自振周期影响的折减系数，框架结构取0.6—0.7，该框架取0.7。——框架结构的顶点假想位移。在未求出框架的周期前，无法求出框架的地震力及位移，是将框架的重力荷载视为水平作用力，求得的假想框架顶点位移。然后由求出，再用求出框架结构的底部剪力。进而求出框架各层剪力和结构真正的位移。框架侧移刚度按求D值的方法计算。柱的侧移刚度按式：。式中可查公式求得。其中，，具体的计算过程和计算结果见表表1底层D值的计算构件名称（KN/m）A轴0.38011813B轴0.45314082D轴0.35310974表22～7层D值的计算

风荷载内力计算6.1.风荷载的计算本地区的基本风压，场地为Ⅱ类场地，地面粗糙度为C类。风压标准值计算公式为：式中：—Z高度出的风振系数，—风荷载体型系数—风压高度变化系数，—基本风压确定各系数的值因结构高度H=22.15m<30m，所以=1.0。查〈〈荷载规范〉〉得值，迎风面=0.8，背风面=-0.5，所以取=1.3。风压高度变化系数可根据各楼层标高处的高度Hi，查表得到标准高度的值，再用线性差值法求得各层高度的值，查得的结果见下表。风压高度变化系数层数Hi（mm）23.251.001.00722.151.001.00619.150.841.00516.150.841.00413.150.741.00310.150.741.0027.150.741.0014.150.741.0015m以下楼层：15m以上20m以下楼层：20m以上楼层：6.1.3将分布风荷载转化为节点集中荷载 按静力等效原理将分布的风荷载转化为节点集中荷载。如下图所示。计算第7层，即屋面处的集中荷载要考虑女儿墙的影响。风荷载如下图所示：风荷载作用下计算简图风荷载作用下框架的内力分析对于风载作用下的各柱的剪力分配，应放在整个楼层中，按照抗侧移刚度在同层中进行分配。框架柱端剪力、弯矩分别按式和式计算，其中、层间剪力、梁柱线刚度比分别取自前面的表格。各柱反弯点高度比y按式确定，其中为标准反弯点高度比，查表确定； 为柱上、下端框架梁相对线刚度变化时反弯点高度比的修正值；为柱的上层层高变化时反弯点高度比的修正值；为柱的下层层高变化时，反弯点高度比的修正值。本设计中，底层柱需要考虑修正值，其余柱均无需修正。具体计算过程见下
