*******本科生毕业设计(论文)第1章建筑设计1.1高层住宅特点[1]高层住宅作为住宅的一种类型,除了具备各类住宅的许多共性外还具有其个性、与多层住宅相比,其根本特点是高,并由此产生了一系列的影响。首先,由于建筑高度增加,在高层建筑中的竖向交通一般由楼梯来完成,电梯起到辅助作用,这样会增加建筑物的造价,从建筑防火的角度看,高层建筑的防火要高于中低层建筑,也会增加高层建筑的工程造价和运行成本。其次,由于建筑高度的增加,在相同的建设场地上,建造高层住宅可以获得更多的建筑面积,这样可以部分解决城市用地紧张和地价高涨的问题。此外,设计精美的高层建筑可以为城市增加景观。第三,从结构受力的角度看,随着高度的增加,侧向荷载(风荷载和水平地震作用)在高层住宅的分析和设计中起着重要的作用,因此,高层住宅的结构分析和设计要比一般的中低层建筑复杂的多。第四,从城市建设和管理的角度看,建筑物向高空延伸,可以缩小城市的平面规模,缩短城市道路和各种公共管线的长度,从而节省城建与管理的投资。由于高层建筑增加人们的聚集密度,缩短了相互间的距离,水平与竖向交通相结合,使人们在地面上的活动走向空间化,节约时间,增加了效率。但是人口过于密集有时会造成交通拥挤、出行困难等问题。第五,建筑高、重量大,近地面大气层对它周围环境都产生了影响,从而在许多设施、建筑构造及局部处理上都要与之相适应,另外,由于高层建筑的重量大,居住人数多,而出现高密度居住,对居民的心理状态、社会环境、城市结构的动态平衡、居住区的空间组织等都带来了新的问题。第六,由于高层住宅的兴建,居住区和城市由水平向发展转向竖向发展,使经济评价方法和范围发生了变化。第七,新的结构形式随之而来的新的施工方式,同时也影响到设计方法和建筑管理。综上所述,建造高层住宅利大于弊,而合理的规划和设计可以达到美化城市环境效果。可以预见,在相当长的一段时间内,高层建筑仍然是城市建设中的主要建筑形式。因此认识这些特点并掌握高层建筑结构的分析理论和基本设计方法,可以为今后的工作打下良好的基础。本建筑属于高层板式住宅,板式住宅,是多层、高层住宅中最常用的一种住宅建筑形式。板式8
*******本科生毕业设计(论文)住宅的平面是条形设计,一幢条形住宅可有多个楼梯,不论是一梯2户,还是一梯3户,每个楼梯的控制面积称为一个“居住单元”。条形的梯间式多层住宅又称为“连续单元式住宅”。板式住宅的特点主要有:(1)每层以楼梯为中心,每层安排户数较少,各户自成一体。(2)户内生活设施完善,既减少了住户之间的相互干扰,又能适应多种气候条件。(3)仍保留一些公共使用面积,如楼梯、走道保证了邻里交往,有助于改善人际关系。(4)建筑面积较小,造价经济合理。单元式住宅彻底改变了旧式住宅相互干扰拥挤不堪的落后状况,为千百万普通家庭提供了独用、舒适又适于标准化、工业化生产的住宅类型。目前,它已成为当今住宅市场上最便于买卖、出租、交换和交易量最高的住宅商品。(5)板式住宅与塔式住宅相比,采光和通风性能好,使居住空间更加舒适,满足现在和未来的发展趋势。1.1总体布局该住宅楼共为十三层,顶部设有电梯机房,一层至十三层均为住户房间。一层分六户,并且对称布置,平面的中心是第二单元的楼电梯间的前室这样布置对抗侧力有利。每套居室室内的平而布置基本上按“大客厅,小卧室”的要求确定的,并且厨房靠近客厅,卫生间靠近卧室,各种居住行为各得其所。1.2平面及竖向交通[2]交通部分的主要功能是通行、出入和防火疏散。交通部分可分为户内交通和户外交通两部分。户内交通一般包括走道、过厅、户内楼梯等。户外交通包括门厅、公共走道、公共楼梯及电梯等。(1)走道套内入口过道净宽不宜小于1.2m;通往卧室、起居室的过道净宽不应小于1m;通往厨房、卫生间、储藏室的过道净宽不应小于0.90m,过道在拐角处的尺寸应便于搬运家具。(2)楼梯及电梯楼梯的尺度要综合考虑人行、防火疏散、家具搬运、自行车及病人担架通过等要求,楼梯间设计应符合现行国家标准《建筑设计防火规范》[3]和《高层民用建筑设计防火规范》的有关规定。楼梯的位置,踏步的尺寸和数量,从考虑高层住宅的特点和一些建筑要求的方面做了设计和计算,楼梯采用直接采光和人工照明相结合,楼梯兼作防烟楼梯。本住宅楼每个单元设有一台电梯,共三台,每台额定载重量为630kg,除可以运送人外,还允许运送残疾人乘坐轮椅及童车。候梯厅深度为1.8m,满足规范要求。8
*******本科生毕业设计(论文)1.4建筑物的朝向选择合理的住宅朝向是住宅区建筑物布置首先考虑的问题,影响建筑物朝向的因素很多,如地理纬度、地段环境、局部气候特征及建筑用地条件等。北方住宅的朝向以朝南为主,板式住宅如本设计的建筑属于朝南,满足规范要求。这种选择主要考虑以下几点:(1)炎热的夏季尽量减少太阳光直射居室外墙或直射室内。(2)夏季有良好的通风,冬季避免冷风吹袭。(3)冬季能有适量的阳光射入室内。(4)尽量适合建筑组合的需要。(5)拟建建筑的交通与已有道路尽量融合一体。(6)充分利用地形。1.5户型设计在分析了我国目前城市人口结构和家庭组成及发展趋势,再结合该地区的实际居住条件决定采用两种户型配套使用,由于目前城市正由主干型转换为核心型。两种户型可以满足不同层次和不同人口的家庭的需要。1.5.1卧室因为是休息的地方所以要求动、静分开的同时,同时也要求同其它房间分隔开来;各人生活各得其所,具有良好的私密性。对房间的要求是隔声效果好,卧室之间不应穿越,同时必须直接采光,自然通风。1.5.2客厅根据中国特色,厅具有客厅、会客室、餐厅的多种功能。本设计中采用了大客厅分别与厨房、卫生间、卧室相邻,成为连接各房间的交通枢纽。起居室内的门窗洞口布置应综合考虑使用功能要求,减少直接开向起居室的门数量.起居室内布置家具的墙面直线长度应大于3m。1.5.3厨房厨房的主要功能是炊事,有的厨房还同时兼有进餐或洗涤的功能,厨房是家务劳动中心。其设计基本要求是:(1)厨房应设置洗涤池、案台、炉灶及排油烟机等设施或预留位置,按炊事操流程排列,操作净长不应小于2.10m。(2)单排布置设备的厨房净宽不应小于1.58
*******本科生毕业设计(论文);双排布置设备的厨房其两排设备的净距不应小于0.90m。(3)厨房应该有直接的采光、自然通风,并宜布置在套内近入口处。基于以上要求,本设计中采用的厨房,满足尺寸要求。1.5.4卫生间卫生间的主要功能包括便溺,漱洗,沐浴,其居住标准、生活水平、自然条件、生活习惯不同,设施标准具有较大的差别。其设计要求为;(1)在满足设备及人体活动空间要求的前提下,力求布置紧凑,设备的尺寸和安装要符合人体工程学要求,以便尽可能减少人的体力消耗。(2)厕所、卫生间是用水较多的场所,其建筑材料的选用及主要注意防水及排水并便于清洁,地面和墙裙应选用防水、又不致于过滑的材料,地面要设置一定坡度。(3)厕所、卫生间产生的蒸汽及其臭味要组织好通风予以排除。最好采用外窗直接通风,否则采用通风道或设小功率排气扇等措施。排风道的排气口应设在接近顶棚的位置。暗厕所,卫生间采用人工照明,有条件的可通过高窗从邻近房间直接间接采光。本设计方案中采用的是公共使用的厕所和浴室。公共使用的厕所的设置与卧室和客厅都较靠近。这样就大大方便了住户。地面均采用防水地面砖,地面低于室内地面30mm。设计1%的坡度以防水流入室内。采光用人工照明,且有通风用的小窗口。1.5.5楼梯本设计中,楼梯宽度为2.520,满足要求。首层楼梯踏步宽260mm,踏步高166.67mm,一跑11阶,二跑7阶;标准层楼梯踏步宽260mm,踏步高168.75mm每跑均8阶。均满足要求。1.5.6大门入口的朝向高层住宅的人口最好放在冬季主导风的背面,因为在迎风面上,越接近建筑物根部中心位置,其风压值越大,如果在这个位置设入口。就成了泄风口,再加上入口必然与垂直交通相连,电梯井与楼梯井就成了披风简,因此会加剧风的烈度,所以人口要尽量避免开向迎风面,有时受总体限制不得不将入口置于迎风面上时,入口就需做适当处理,本设计的高层住宅选择北向入口,因为该地区冬季主导风向为西南风,所以选择合理。1.5.7设施与设备公共设备有电话线、配电设备、宽带网线等。室内有抽油烟机、浴缸、配有热水器喷头、可视门铃等。8
*******本科生毕业设计(论文)1.5.8阳台及栏杆阳台是楼层住户与大自然相联系的部分。它按其使用性质可分为生活阳和服务阳台,阳台设计中问题有尺寸、朝向、通风、视线、排水安全及附属设施几个方面。由于高层住宅的窗台距地面较高,再加之周围风速较大,易使产生心理上危险感,因此本建筑采用室内阳台,通风、采光良好的同时给人以安全、舒适的感觉。1.5.9防火设计[4]各套户型的进户门均采用防盗门,如某一住户发生火灾可及时关闭防火门,防止火势蔓延,使住户有足够的时间脱离危险区,保证了住户的生命安全,进入楼梯入口的门为乙级防火门,耐火极限为1.2小时,该楼梯是发生火灾时居民疏散的主要通道采用封闭式楼梯间,可以有效地减少火灾造成的人生伤亡,为了有利于消防员及时运送消防器材和救护伤员,设计时在电梯前室入口,同样设置了乙级防火门。根据规范规定设置防烟楼梯,楼梯间入口处设有前室,前室内设有送风、排烟竖井,供疏散人员一经到达前室,就达到了第一个安全地点,如果烟一旦侵入前室,基本上可以从前室排除。1.5.10使用房间的分类从使用房间的功能要求分类。住宅中的房间有客厅、餐厅、卧室、卫生间和厨房。A户型(三室二厅)建筑面积110.08m2主卧室的面积17.85m2卧室1的面积12.14m2卧室2的面积11.34m2客厅的面积26.30m2厨房和餐厅的面积16.39m2卫生间的面积5.41m2、4.26m2B户型(二室二厅)建筑面积85.97m2主卧室的面积14.33m2卧室1的面积13.03m2餐厅的面积26.30m2厨房和餐厅的面积16.39m2卫生间的面积4.57m28
*******本科生毕业设计(论文)1.5.11门窗在房间平面中的布置两个户型的入户门宽为1000mm、卧室门均为宽900mm,其中入户门为防盗门,卧室门为成品木门;卫生间门宽700mm、厨房门宽为700mm,采用900mm的门可使一个携带东西的人方便的通过也能搬进书柜等尺寸较大的家具;700mm的门稍大于一个人通过宽度,这些较小的门扇,开启时可以少占室内的使用面积这对平面紧凑的核心式住宅显得更加重要。窗的高度1.5m。主卧室内设有室内阳台,采用门宽为700mm。因设计中使用了最新的地热式供暖方式,所以暖气被取消了,窗的面积可以相应的增大了。窗的位置考虑采光和通风的要求设置,使各房间的采光均满足规范所规定的窗地比的要求。8
*******本科生毕业设计(论文)第1章结构设计1.1概述[5]2.1.1工程概况该13层高层住宅楼,采用现浇钢筋混凝土剪力墙结构、墙下条形桩基,标准层建筑平面布置如图所示,主体结构高度为35.4m,首层层高3.0m,标准层层高2.7m,突出屋面电梯机房层高3.3m,结构主体总高度38.70m。该工程抗震设防烈度为7度,场地类别为Ⅱ类,设计地震分组为第一组,基本风压0.55kN/m2,地面粗糙度为B类,基本雪压为0.45kN/m2;该房屋为丙类建筑。2.1.2主体结构布置该剪力墙结构平面布置对称,凸出、凹进尺寸符合规范要求;结构侧向刚度沿竖向变化均匀,无刚度突变;结构高宽比为H/B〈5;每个独立墙肢段的高宽比均大于2,且墙肢长度均小于8m。剪力墙门洞口上下对齐,形成了明确的墙肢和连梁。2.1.3材料的选用及剪力墙截面尺寸的确定剪力墙结构的混凝土强度等级选用C30,钢筋采用HPB235和HRB300级。剪力墙厚度按抗震等级设计时不应小于楼层高度的1/20且不应小于160mm,本工程剪力墙采用双排配筋,剪力墙截面的厚度均为180mm。2.1.4剪力墙截面的类型判别及刚度计算根据抗震设计的一般原则,对称结构的两个主轴方向均应进行抗震计算。限于篇幅,只对一个方向进行计算,且假定结构无扭转。另外,根据《高层规程》,在计算剪力墙结构的内力和位移时,可以不考虑纵横墙的共同工作,为了简化计算,不考虑纵横墙的共同工作。2.1.4.1剪力墙的类型判别由图可得Y方向上各片剪力墙的平面尺寸,该工程外墙的门窗洞口高度均为1500mm,则一层门窗洞口处连梁高度均为1500mm,其他层门窗洞口处连梁高度均为1200,内墙门窗洞口的高度均为2100mm,则一层内墙门窗洞口处的连梁高度为900mm,其他层内墙门窗洞口处的连梁高度为600mm。8

*******本科生毕业设计(论文)选配812()根据构造要求箍筋选配筋图见施工图.结论本毕业设计课题是高层住宅楼的设计,高层建筑可以反映出一个城市经济繁荣和进步的程度。随着社会的发展与进步,城市人口的增加,城市对高层建筑的规模和高度不断增加。建造高层建筑可以缓解城市用地紧张问题。根据所给的设计任务书的要求,在指导老师的热心指导下,经过十几周的努力主要进行了以下几个方面的设计工作:1.建筑设计:综合考虑总体布局、水平与竖向交通、建筑朝向、户型选择、通风、采光、防火与疏散以及功能分区等方面的要求。2.结构设计:综合考虑建筑物的整体性和抗震设防的需要,采用剪力墙结构体系,刚度大、稳定性好可以满足住户的要求。3.荷载计算:对于高层建筑物来说,侧向力起控制作用,因此在本设计中主要考虑水平地震作用以及风荷载的影响,并综合竖向荷载的影响对其进行了内力组合,近而选出最不利的内力组合方式,为墙体配筋计算提供了一个前提。4.截面设计:完成了墙体截面的配筋计算以及斜截面的抗剪计算。5.基础设计:综合考虑设计任务书所提供的地质条件和剪力墙结构体系的特点,采用了整体性较好的墙下条形桩基础,并对其进行了结构设计计算。6.施工图纸:根据统一规定绘制了建筑图(平面、立面、剖面)和结构图(首层结构布置图、板的配筋图、基础平面布置图以及墙体配筋图)。71
