Midascivil荷载组合详解.docx

1、Midascivil荷载组合详解主要根据公路桥涵设计通用规范(JTGD60-2004)编制。在结果荷载组合对话框中选择“自动生成”功能。a.在荷载移动荷载分析数据中定义移动荷载时，下面组合中的符号L用ML代替。b.反应谱荷载工况的简称为ESPc.在荷载移动荷载分析数据中，将人群荷载按移动荷载定义，并在移动荷载工况中将其与其它汽车荷载子荷载工况进行组合时(在移动荷载工况中选择“组合”)，在定义人群荷载子荷载工况时，系数应取0.8(根据通用规范4.1.6条第1项)。为了考虑人群荷载单独作用的情况(系数1.0的情况)，需要另外单独定义一个人群荷载移动工况。d.下面组合中考虑了可变荷载作用的不同时组合

2、(JTGD60-2004e.不考虑汽车荷载的恒荷载+其他可变荷载的组合及组合值系数需用户另外添加(规范无规定)。f.永久荷载中既有对结构承载能力不利，又有对结构的承载能力有利的永久荷载时，需要用户另外添加组合或修改“永久荷载对结构的承载能力有利组合”中的系数。g.在荷载组合自动生成对话框中选择“考虑弯桥制动力”时，当汽车制动力与离心力同时出现在荷载组合中时，制动力荷载的组合系数自动乘以0.7的系数。h.程序会自动生成各状态组合的包络组合。i.钢结构的组合依然沿用旧规范。j.当有移动荷载作用时，在设计中实际采用的组合会更多(对每个荷载组合都会对弯矩最大时、剪力最大时、轴力最大时的情况进行验算)。

3、k.在荷载静力荷载工况中定义荷载名称，但没有具体定义荷载值时，荷载组合的自动生成功能将不包含该荷载工况名称。l.预应力混凝土设计荷载组合在荷载组合的“混凝土”中定义。a)永久荷载对结构的承载能力不利(120个)恒荷载组合(1个):1.2*D+1.2*PS+1.2*EV+1.4*EH+1.0*(SH+CR)+1.0*B+0.5*STL永久荷载+1个可变作用(8个):1.2*D+1.2*PS+1.2*EV+1.4*EH+1.0*(SH+CR)+1.0*B+0.5*STL+1.4*(L+IL+CF)1.2*D+1.2*PS+1.2*EV+1.4*EH+1.0*(SH+CR)+1.0*B+0.5*ST
