玻璃幕墙临时悬挑架验算书.docx

1、玻璃幕墙临时悬挑架验算书宁波市轨道交通1号线工程天童庄车辆段与综合基地工程玻璃幕墙临时悬挑架验算书编制： 复核： 审批： 中铁四局装饰公司宁波天童庄项目部二一三年十一月四日玻璃幕墙临时悬挑架验算书一、计算依据钢结构设计规范GB50017- 2003，建筑施工碗扣式钢管脚手架安全技术规范JGJ166-2008。二、计算说明悬挑架搭设形式详见施工方案，简图如下：立面图平面图考虑实际钢管壁厚偏差，计算参数中钢管采用483.0，抗拉、抗压和抗弯强度设计值f= 215N/mm2，抗剪强度设计值f= 125N/mm2，截面面积A=424.1mm2，截面抵抗矩W=8.985cm3，截面惯性矩I=10.783

2、cm4，弹性模量E=2.06105N/mm2。钢管截面参数见下图：三、荷载取值竹笆脚手板：0.10kN/m2，安全网0.01 kN/m2，施工活载2.0 kN/m2。计算可得单根悬挑钢管：q竹笆=0.15 kN/m，q活载=3.0 kN/m，安全网荷载f=0.2166 kN。四、荷载建立选取一个楼层进行受力分析，建立力学模型，建立荷载如下:1.结构自重2.竹笆均布荷载3.施工荷载1、2、3（同一楼层悬挑作业层三层，同时作业按一层考虑，不同作业层荷载从上自下编号为施工荷载1、2、3）4.附载（主要是安全网荷载）五、工况建立施工荷载按照同时作业一层考虑，分析工况共9类，如下：1、LCB1承载能力相

3、加自重(1.350)+竹笆(1.350)+附载(1.350)+施工荷载2(0.980)2、LCB2承载能力相加自重(1.350)+竹笆(1.350)+附载(1.350)+施工荷载1(0.980)3、LCB3承载能力相加自重(1.350)+竹笆(1.350)+附载(1.350)+施工荷载3(0.980)4、LCB4承载能力相加自重(1.200)+竹笆(1.200)+附载(1.200)+施工荷载1(1.400)5、LCB5承载能力相加自重(1.200)+竹笆(1.200)+附载(1.200)+施工荷载2(1.400)6、LCB6承载能力相加自重(1.200)+竹笆(1.200)+附载(1.200)

4、+施工荷载3(1.400)7、LCB7承载能力相加自重(1.000)+竹笆(1.000)+附载(1.000)+施工荷载1(1.400)8、LCB8承载能力相加自重(1.000)+竹笆(1.000)+附载(1.000)+施工荷载2(1.400)9、LCB9承载能力相加自重(1.000)+竹笆(1.000)+附载(1.000)+施工荷载3(1.400)六、整体性验算采用计算软件建模。材料、截面、节点、单元、节点荷载设置较为简单，在此不赘述。边界条件采用一般支承，如下图：计算结果如下：计算受力结果均为程序输出，以荷载组合LCB6为例，位移图如下：内力图如下：应力图如下：其他荷载位移和受力模型不一一列

5、出，最不利荷载组合截面验算结果如下：由上图可知，受力最大构件为105号构建，验算结果满足要求，各个单元构建的验算结果如下表，均满足要求。检算合格。单元验算表CHKMEMBSECT选择截面名称截面名称LCBLenLyKyBmyNMbMyMzCHKCOMSHR选择材料FyLCBLbLzKzBmzNrMrbMryMrzOK510钢管钢管60.90.911114.098104.507104.5070OK0.1080.009Q2352.40E+0860.90.91191184.70965.988965.988OK610钢管钢管60.90.911521.579122.661122.6610OK0.1270
