1、钢筋混凝土T梁计算一.设计资料1.跨径:标准跨径lb=20.00m,计算跨径为L=19.50m。2.桥面净空:0.5+净8+0.5m3.设计荷载:公路—Ⅱ级4.材料:T梁为C30混凝土; 铰缝为C30细骨料混凝土; 桥面铺装采用10cmC30混凝土及5cm沥青混凝土;栏杆及护栏底座C30混凝土。5.设计依据、参考书及使用程序(1)《公路桥涵设计通用规范》JTGD60-2004;(2)《公路钢筋混凝土及预应力混凝土桥涵设计规范》JTGD62-2004;(3)《公路工程技术标准》(4)《桥梁工程》(5)桥梁博士网络版二.构造型式及尺寸见11-12页图纸三.内力计算采用新规范计算,主要计算弯矩及剪力
2、的影响。程序内力计算结果见11-12页。采用桥梁博士计算,计算各相关系数取值如下:1.车道荷载横向分布系数计算荷载横向分布系数跨中和L/4处按铰接板法计算,支点按杠杆原理法计算,支点至L/4点之间按直线内插求得。(1)跨中及L/4处的荷载横向分布系数用桥梁博士的“截面设计”模块计算截面特性,结果见6-7页用桥梁博士的“横向分布”模块计算荷载横向分布系数,结果见9-10页(2)支点处的荷载横向分布系数用桥梁博士的“横向分布”模块计算荷载横向分布系数,采用混合影响线加载,结果见10页(3)支点到L/4处的荷载横向分布系数荷载横向分布系数 荷载位置跨中及L/4支点跨径(m) 20边梁0.3780.4
