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(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(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)。
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。

除基础变位作用以外的作用(永久作用、可变作用、地震作用)的分项系数均取。
其他偶然作用不参与组合。
反应谱地震作用既生成+号组合,又生成-号组合。
2)船舶或漂流物的撞击作用组合组合类型同基本组合,仅将船舶或漂流物的撞击作用的分项系数取。
因为规范没有明确该项组合的各作用分项系数,用户可修改该项组合的系数或将撞击作用定义为用户定义荷载类型,手工参与组合。
3)汽车撞击作用组合组合类型同基本组合,仅将船舶或漂流物的撞击作用的分项系数取。
